Disabling SSL verification

All Watson services use Secure Sockets Layer (SSL) (or Transport Layer Security (TLS)) for secure connections between the client and server. The connection is verified against the local certificate store to ensure authentication, integrity, and confidentiality.

If you use a self-signed certificate, you need to disable SSL verification to make a successful connection.

Enabling SSL verification is highly recommended. Disabling SSL jeopardizes the security of the connection and data. Disable SSL only if necessary, and take steps to enable SSL as soon as possible.

To disable SSL verification for a curl request, use the --insecure (-k) option with the request.

To disable SSL verification, create an HttpConfigOptions object and set the disableSslVerification property to true. Then, pass the object to the service instance by using the configureClient method.

To disable SSL verification, set the disableSslVerification parameter to true when you create the service instance.

To disable SSL verification, specify True on the set_disable_ssl_verification method for the service instance.

To disable SSL verification, set the disable_ssl_verification parameter to true in the configure_http_client() method for the service instance.

To disable SSL verification, call the DisableSSLVerification method on the service instance.

To disable SSL verification, call the disableSSLVerification() method on the service instance. You cannot disable SSL verification on Linux.

To disable SSL verification, set the DisableSslVerification method to true on the service instance.

To disable SSL verification, set the DisableSslVerification method to true on the service instance.

Example to disable SSL verification. Replace {apikey} and {url} with your service credentials.

curl -k -X {request_method} -u "apikey:{apikey}" "{url}/{method}"

Example to disable SSL verification

IamAuthenticator authenticator = new IamAuthenticator("{apikey}");
LanguageTranslator languageTranslator = new LanguageTranslator("{version}", authenticator);
languageTranslator.setServiceUrl("{url}");

HttpConfigOptions configOptions = new HttpConfigOptions.Builder()
  .disableSslVerification(true)
  .build();
languageTranslator.configureClient(configOptions);

Example to disable SSL verification

const LanguageTranslatorV3 = require('ibm-watson/language-translator/v3');
const { IamAuthenticator } = require('ibm-watson/auth');

const languageTranslator = new LanguageTranslatorV3({
  version: '{version}',
  authenticator: new IamAuthenticator({
    apikey: '{apikey}',
  }),
  serviceUrl: '{url}',
  disableSslVerification: true,

languageTranslator.DisableSslVerification = true;

Authentication

You authenticate to the API by using IBM Cloud Identity and Access Management (IAM).

You can pass either a bearer token in an authorization header or an API key. Tokens support authenticated requests without embedding service credentials in every call. API keys use basic authentication. For more information, see Authenticating to Watson services.

  • For testing and development, you can pass an API key directly.
  • For production use, unless you use the Watson SDKs, use an IAM token.

If you pass in an API key, use apikey for the username and the value of the API key as the password. For example, if the API key is f5sAznhrKQyvBFFaZbtF60m5tzLbqWhyALQawBg5TjRI in the service credentials, include the credentials in your call like this:

curl -u "apikey:f5sAznhrKQyvBFFaZbtF60m5tzLbqWhyALQawBg5TjRI"

For IBM Cloud instances, the SDK provides initialization methods for each form of authentication.

  • Use the API key to have the SDK manage the lifecycle of the access token. The SDK requests an access token, ensures that the access token is valid, and refreshes it if necessary.
  • Use the access token to manage the lifecycle yourself. You must periodically refresh the token.

Access between services

Your application might use more than one Watson service. You can grant access between services and you can grant access to more than one service for your applications.

For IBM Cloud services, the method to grant access between Watson services varies depending on the type of API key. For more information, see IAM access.

  • To grant access between IBM Cloud services, create an authorization between the services. For more information, see Granting access between services.
  • To grant access to your services by applications without using user credentials, create a service ID, add an API key, and assign access policies. For more information, see Creating and working with service IDs.

When you give a user ID access to multiple services, use an endpoint URL that includes the service instance ID (for example, https://api.us-south.language-translator.watson.cloud.ibm.com/instances/6bbda3b3-d572-45e1-8c54-22d6ed9e52c2). You can find the instance ID in two places:

  • By clicking the service instance row in the Resource list. The instance ID is the GUID in the details pane.

  • By clicking the name of the service instance in the list and looking at the credentials URL.

    If you don't see the instance ID in the URL, the credentials predate service IDs. Add new credentials from the Service credentials page and use those credentials.

Versioning

API requests require a version parameter that takes a date in the format version=YYYY-MM-DD. When the API is updated with any breaking changes, the service introduces a new version date for the API.

Send the version parameter with every API request. The service uses the API version for the date you specify, or the most recent version before that date. Don't default to the current date. Instead, specify a date that matches a version that is compatible with your app, and don't change it until your app is ready for a later version.

Specify the version to use on API requests with the version parameter when you create the service instance. The service uses the API version for the date you specify, or the most recent version before that date. Don't default to the current date. Instead, specify a date that matches a version that is compatible with your app, and don't change it until your app is ready for a later version.

This documentation describes the current version of Language Translator, 2018-05-01. In some cases, differences in earlier versions are noted in the descriptions of parameters and response models.

Error handling

Language Translator uses standard HTTP response codes to indicate whether a method completed successfully. HTTP response codes in the 2xx range indicate success. A response in the 4xx range is some sort of failure, and a response in the 5xx range usually indicates an internal system error that cannot be resolved by the user. Response codes are listed with the method.

ErrorResponse

Data handling

Additional headers

Some Watson services accept special parameters in headers that are passed with the request.

You can pass request header parameters in all requests or in a single request to the service.

To pass a request header, use the --header (-H) option with a curl request.

To pass header parameters with every request, use the setDefaultHeaders method of the service object. See Data collection for an example use of this method.

To pass header parameters in a single request, use the addHeader method as a modifier on the request before you execute it.

To pass header parameters with every request, specify the headers parameter when you create the service object. See Data collection for an example use of this method.

To pass header parameters in a single request, use the headers method as a modifier on the request before you execute it.

Response details

The Language Translator service might return information to the application in response headers.

To access all response headers that the service returns, include the --include (-i) option with a curl request. To see detailed response data for the request, including request headers, response headers, and extra debugging information, include the --verbose (-v) option with the request.

Example request to access response headers

curl -X {request_method} {authentication_method} --include "{url}/v3/{method}"

To access information in the response headers, use one of the request methods that returns details with the response: executeWithDetails(), enqueueWithDetails(), or rxWithDetails(). These methods return a Response<T> object, where T is the expected response model. Use the getResult() method to access the response object for the method, and use the getHeaders() method to access information in response headers.

Example request to access response headers

Response<ReturnType> response = languageTranslator.methodName(parameters)
  .executeWithDetails();
// Access response from methodName
ReturnType returnValue = response.getResult();
// Access information in response headers
Headers responseHeaders = response.getHeaders();

All response data is available in the Response<T> object that is returned by each method. To access information in the response object, use the following properties.

Property Description
result Returns the response for the service-specific method.
headers Returns the response header information.
status Returns the HTTP status code.

Example request to access response headers

languageTranslator.methodName(parameters)
  .then(response => {
    console.log(response.headers);
  })
  .catch(err => {
    console.log('error:', err);
  });

The return value from all service methods is a DetailedResponse object. To access information in the result object or response headers, use the following methods.

DetailedResponse

Method Description
get_result() Returns the response for the service-specific method.
get_headers() Returns the response header information.
get_status_code() Returns the HTTP status code.

Example request to access response headers

language_translator.set_detailed_response(True)
response = language_translator.methodName(parameters)
# Access response from methodName
print(json.dumps(response.get_result(), indent=2))
# Access information in response headers
print(response.get_headers())
# Access HTTP response status
print(response.get_status_code())

The return value from all service methods is a DetailedResponse object. To access information in the response object, use the following properties.

DetailedResponse

Property Description
result Returns the response for the service-specific method.
headers Returns the response header information.
status Returns the HTTP status code.

DetailedResponse

Method Description
GetResult() Returns the response for the service-specific method.
GetHeaders() Returns the response header information.
GetStatusCode() Returns the HTTP status code.

Example request to access response headers

import (
  "github.com/IBM/go-sdk-core/core"
  "github.com/watson-developer-cloud/go-sdk/languagetranslatorv3"
)
result, response, responseErr := languageTranslator.MethodName(
  &methodOptions{})
// Access result
core.PrettyPrint(response.GetResult(), "Result ")

// Access response headers
core.PrettyPrint(response.GetHeaders(), "Headers ")

// Access status code
core.PrettyPrint(response.GetStatusCode(), "Status Code ")

All response data is available in the WatsonResponse<T> object that is returned in each method's completionHandler.

Example request to access response headers

languageTranslator.methodName(parameters) {
  response, error in

  guard let result = response?.result else {
    print(error?.localizedDescription ?? "unknown error")
    return
  }
  print(result) // The data returned by the service
  print(response?.statusCode)
  print(response?.headers)
}

The response contains fields for response headers, response JSON, and the status code.

DetailedResponse

Property Description
Result Returns the result for the service-specific method.
Response Returns the raw JSON response for the service-specific method.
Headers Returns the response header information.
StatusCode Returns the HTTP status code.

Example request to access response headers

var results = languageTranslator.MethodName(parameters);

var result = results.Result;            //  The result object

}

private void Callback(DetailedResponse<ResponseType> response, IBMError error)
{
    var result = response.Result;                 //  The result object
    var responseHeaders = response.Headers;       //  The response headers
    var responseJson = reresponsesults.Response;  //  The raw response JSON
    var statusCode = response.StatusCode;         //  The response status code
}

Data collection

By default, Language Translator service instances that are not part of Premium plans collect data about API requests and their results. This data is collected only to improve the services for future users. The collected data is not shared or made public. Data is not collected for services that are part of Premium plans.

To prevent IBM usage of your data for an API request, set the X-Watson-Learning-Opt-Out header parameter to true.

You must set the header on each request that you do not want IBM to access for general service improvements.

You can set the header by using the setDefaultHeaders method of the service object.

You can set the header by using the headers parameter when you create the service object.

You can set the header by using the set_default_headers method of the service object.

You can set the header by using the add_default_headers method of the service object.

You can set the header by using the SetDefaultHeaders method of the service object.

You can set the header by adding it to the defaultHeaders property of the service object.

You can set the header by using the WithHeader() method of the service object.

Example request

curl -u "apikey:{apikey}" -H "X-Watson-Learning-Opt-Out: true" "{url}/{method}"

Example request

Map<String, String> headers = new HashMap<String, String>();
headers.put("X-Watson-Learning-Opt-Out", "true");

languageTranslator.setDefaultHeaders(headers);

Example request

const LanguageTranslatorV3 = require('ibm-watson/language-translator/v3');
const { IamAuthenticator } = require('ibm-watson/auth');

const languageTranslator = new LanguageTranslatorV3({
  version: '{version}',
  authenticator: new IamAuthenticator({
    apikey: '{apikey}',
  }),
  serviceUrl: '{url}',
  headers: {
    'X-Watson-Learning-Opt-Out': 'true'
  }
});

Example request

language_translator.set_default_headers({'x-watson-learning-opt-out': "true"})

Example request

language_translator.add_default_headers(headers: {"x-watson-learning-opt-out" => "true"})

Example request

import "net/http"

headers := http.Header{}
headers.Add("x-watson-learning-opt-out", "true")
languageTranslator.SetDefaultHeaders(headers)

Example request

languageTranslator.defaultHeaders["X-Watson-Learning-Opt-Out"] = "true"

Example request

IamAuthenticator authenticator = new IamAuthenticator(
    apikey: "{apikey}"
    );

LanguageTranslatorService languageTranslator = new LanguageTranslatorService("{version}", authenticator);
languageTranslator.SetServiceUrl("{url}");

languageTranslator.WithHeader("X-Watson-Learning-Opt-Out", "true");

Example request

var authenticator = new IamAuthenticator(
    apikey: "{apikey}"
);

while (!authenticator.CanAuthenticate())
    yield return null;

var languageTranslator = new LanguageTranslatorService("{version}", authenticator);
languageTranslator.SetServiceUrl("{url}");

languageTranslator.WithHeader("X-Watson-Learning-Opt-Out", "true");

Synchronous and asynchronous requests

The Java SDK supports both synchronous (blocking) and asynchronous (non-blocking) execution of service methods. All service methods implement the ServiceCall interface.

  • To call a method synchronously, use the execute method of the ServiceCall interface. You can call the execute method directly from an instance of the service.
  • To call a method asynchronously, use the enqueue method of the ServiceCall interface to receive a callback when the response arrives. The ServiceCallback interface of the method's argument provides onResponse and onFailure methods that you override to handle the callback.

The Ruby SDK supports both synchronous (blocking) and asynchronous (non-blocking) execution of service methods. All service methods implement the Concurrent::Async module. When you use the synchronous or asynchronous methods, an IVar object is returned. You access the DetailedResponse object by calling ivar_object.value.

For more information about the Ivar object, see the IVar class docs.

  • To call a method synchronously, either call the method directly or use the .await chainable method of the Concurrent::Async module.

    Calling a method directly (without .await) returns a DetailedResponse object.

  • To call a method asynchronously, use the .async chainable method of the Concurrent::Async module.

You can call the .await and .async methods directly from an instance of the service.

Example synchronous request

ReturnType returnValue = languageTranslator.method(parameters).execute();

Example asynchronous request

languageTranslator.method(parameters).enqueue(new ServiceCallback<ReturnType>() {
  @Override public void onResponse(ReturnType response) {
    . . .
  }
  @Override public void onFailure(Exception e) {
    . . .
  }
});

Example synchronous request

response = language_translator.method_name(parameters)

or

response = language_translator.await.method_name(parameters)

Example asynchronous request

response = language_translator.async.method_name(parameters)

Methods

List supported languages

Lists all supported languages for translation. The method returns an array of supported languages with information about each language. Languages are listed in alphabetical order by language code (for example, af, ar). In addition to basic information about each language, the response indicates whether the language is supported_as_source for translation and supported_as_target for translation. It also lists whether the language is identifiable.

                          Create model

                          Uploads training files to customize a translation model. You can customize a model with a forced glossary or with a parallel corpus:

                          • Use a forced glossary to force certain terms and phrases to be translated in a specific way. You can upload only a single forced glossary file for a model. The size of a forced glossary file for a custom model is limited to 10 MB.
                          • Use a parallel corpus when you want your custom model to learn from general translation patterns in parallel sentences in your samples. What your model learns from a parallel corpus can improve translation results for input text that the model has not been trained on. You can upload multiple parallel corpora files with a request. To successfully train with parallel corpora, the corpora files must contain a cumulative total of at least 5000 parallel sentences. The cumulative size of all uploaded corpus files for a custom model is limited to 250 MB.

                          Depending on the type of customization and the size of the uploaded files, training time can range from minutes for a glossary to several hours for a large parallel corpus. To create a model that is customized with a parallel corpus and a forced glossary, customize the model with a parallel corpus first and then customize the resulting model with a forced glossary.

                          You can create a maximum of 10 custom models per language pair. For more information about customizing a translation model, including the formatting and character restrictions for data files, see Customizing your model.

                          Supported file formats

                          You can provide your training data for customization in the following document formats:

                          • TMX (.tmx) - Translation Memory eXchange (TMX) is an XML specification for the exchange of translation memories.
                          • XLIFF (.xliff) - XML Localization Interchange File Format (XLIFF) is an XML specification for the exchange of translation memories.
                          • CSV (.csv) - Comma-separated values (CSV) file with two columns for aligned sentences and phrases. The first row must have two language codes. The first column is for the source language code, and the second column is for the target language code.
                          • TSV (.tsv or .tab) - Tab-separated values (TSV) file with two columns for aligned sentences and phrases. The first row must have two language codes. The first column is for the source language code, and the second column is for the target language code.
                          • JSON (.json) - Custom JSON format for specifying aligned sentences and phrases.
                          • Microsoft Excel (.xls or .xlsx) - Excel file with the first two columns for aligned sentences and phrases. The first row contains the language code.

                          You must encode all text data in UTF-8 format. For more information, see Supported document formats for training data.

                          Specifying file formats

                          You can indicate the format of a file by including the file extension with the file name. Use the file extensions shown in Supported file formats.

                          Alternatively, you can omit the file extension and specify one of the following content-type specifications for the file:

                          • TMX - application/x-tmx+xml
                          • XLIFF - application/xliff+xml
                          • CSV - text/csv
                          • TSV - text/tab-separated-values
                          • JSON - application/json
                          • Microsoft Excel - application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

                          For example, with curl, use the following content-type specification to indicate the format of a CSV file named glossary:

                          --form "forced_glossary=@glossary;type=text/csv"

                          Uploads training files to customize a translation model. You can customize a model with a forced glossary or with a parallel corpus:

                          Alternatively, you can omit the file extension and specify one of the following content-type specifications for the file:

                          • TMX - application/x-tmx+xml
                          • XLIFF - application/xliff+xml
                          • CSV - text/csv
                          • TSV - text/tab-separated-values
                          • JSON - application/json
                          • Microsoft Excel - application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

                          For example, with curl, use the following content-type specification to indicate the format of a CSV file named glossary:

                          --form "forced_glossary=@glossary;type=text/csv".

                          Uploads training files to customize a translation model. You can customize a model with a forced glossary or with a parallel corpus:

                          • Use a forced glossary to force certain terms and phrases to be translated in a specific way. You can upload only a single forced glossary file for a model. The size of a forced glossary file for a custom model is limited to 10 MB.
                          • Use a parallel corpus when you want your custom model to learn from general translation patterns in parallel sentences in your samples. What your model learns from a parallel corpus can improve translation results for input text that the model has not been trained on. You can upload multiple parallel corpora files with a request. To successfully train with parallel corpora, the corpora files must contain a cumulative total of at least 5000 parallel sentences. The cumulative size of all uploaded corpus files for a custom model is limited to 250 MB.

                          Depending on the type of customization and the size of the uploaded files, training time can range from minutes for a glossary to several hours for a large parallel corpus. To create a model that is customized with a parallel corpus and a forced glossary, customize the model with a parallel corpus first and then customize the resulting model with a forced glossary.

                          You can create a maximum of 10 custom models per language pair. For more information about customizing a translation model, including the formatting and character restrictions for data files, see Customizing your model.

                          Supported file formats

                          You can provide your training data for customization in the following document formats:

                          • TMX (.tmx) - Translation Memory eXchange (TMX) is an XML specification for the exchange of translation memories.
                          • XLIFF (.xliff) - XML Localization Interchange File Format (XLIFF) is an XML specification for the exchange of translation memories.
                          • CSV (.csv) - Comma-separated values (CSV) file with two columns for aligned sentences and phrases. The first row must have two language codes. The first column is for the source language code, and the second column is for the target language code.
                          • TSV (.tsv or .tab) - Tab-separated values (TSV) file with two columns for aligned sentences and phrases. The first row must have two language codes. The first column is for the source language code, and the second column is for the target language code.
                          • JSON (.json) - Custom JSON format for specifying aligned sentences and phrases.
                          • Microsoft Excel (.xls or .xlsx) - Excel file with the first two columns for aligned sentences and phrases. The first row contains the language code.

                          You must encode all text data in UTF-8 format. For more information, see Supported document formats for training data.

                          Specifying file formats

                          You can indicate the format of a file by including the file extension with the file name. Use the file extensions shown in Supported file formats.

                          Alternatively, you can omit the file extension and specify one of the following content-type specifications for the file:

                          • TMX - application/x-tmx+xml
                          • XLIFF - application/xliff+xml
                          • CSV - text/csv
                          • TSV - text/tab-separated-values
                          • JSON - application/json
                          • Microsoft Excel - application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

                          For example, with curl, use the following content-type specification to indicate the format of a CSV file named glossary:

                          --form "forced_glossary=@glossary;type=text/csv".

                          Uploads training files to customize a translation model. You can customize a model with a forced glossary or with a parallel corpus:

                          • Use a forced glossary to force certain terms and phrases to be translated in a specific way. You can upload only a single forced glossary file for a model. The size of a forced glossary file for a custom model is limited to 10 MB.
                          • Use a parallel corpus when you want your custom model to learn from general translation patterns in parallel sentences in your samples. What your model learns from a parallel corpus can improve translation results for input text that the model has not been trained on. You can upload multiple parallel corpora files with a request. To successfully train with parallel corpora, the corpora files must contain a cumulative total of at least 5000 parallel sentences. The cumulative size of all uploaded corpus files for a custom model is limited to 250 MB.

                          Depending on the type of customization and the size of the uploaded files, training time can range from minutes for a glossary to several hours for a large parallel corpus. To create a model that is customized with a parallel corpus and a forced glossary, customize the model with a parallel corpus first and then customize the resulting model with a forced glossary.

                          You can create a maximum of 10 custom models per language pair. For more information about customizing a translation model, including the formatting and character restrictions for data files, see Customizing your model.

                          Supported file formats

                          You can provide your training data for customization in the following document formats:

                          • TMX (.tmx) - Translation Memory eXchange (TMX) is an XML specification for the exchange of translation memories.
                          • XLIFF (.xliff) - XML Localization Interchange File Format (XLIFF) is an XML specification for the exchange of translation memories.
                          • CSV (.csv) - Comma-separated values (CSV) file with two columns for aligned sentences and phrases. The first row must have two language codes. The first column is for the source language code, and the second column is for the target language code.
                          • TSV (.tsv or .tab) - Tab-separated values (TSV) file with two columns for aligned sentences and phrases. The first row must have two language codes. The first column is for the source language code, and the second column is for the target language code.
