Watson Assistant v2 | IBM Cloud API Docs

Introduction

Last updated: 2023-05-25

The IBM Watson™ Assistant service combines machine learning, natural language understanding, and an integrated dialog editor to create conversation flows between your apps and your users.

The Assistant v2 API provides runtime methods your client application can use to send user input to an assistant and receive a response.

The IBM Watson Unity SDK has the following requirements.

The SDK requires Unity version 2018.2 or later to support Transport Layer Security (TLS) 1.2.
- Set the project settings for both the Scripting Runtime Version and the Api Compatibility Level to .NET 4.x Equivalent.
- For more information, see TLS 1.0 support.
The SDK doesn't support the WebGL projects. Change your build settings to any platform except WebGL.

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.

Example to disable SSL verification with a service managed on IBM Cloud. Replace {apikey} and {url} with your service credentials.

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

Authentication

IBM Cloud services use IBM Cloud Identity and Access Management (IAM) to authenticate. With IBM Cloud Pak for Data, you pass a bearer token.

IBM Cloud

For IBM Cloud instances, 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.

The service access role that is associated with the API key determines which endpoints and methods you can access. For more information, see Resource-level role impact on available actions.

Cloud Pak for Data

For Cloud Pak for Data, you pass a bearer token in an Authorization header to authenticate to the API. The token is associated with a username.

For testing and development, you can use the bearer token that's displayed in the Cloud Pak for Data web client. To find this token, view the details for the service instance by clicking the name of the service in your list of instances. The details also include the service endpoint URL. Don't use this token in production because it does not expire.
For production use, create a user in the Cloud Pak for Data web client to use for authentication. Generate a token from that user's credentials with the POST /v1/authorize method.

For more information, see the Get authorization token method of the Cloud Pak for Data API reference.

For Cloud Pak for Data instances, pass either username and password credentials or a bearer token that you generate to authenticate to the API. Username and password credentials use basic authentication. However, the SDK manages the lifecycle of the token. Tokens are temporary security credentials. If you pass a token, you maintain the token lifecycle.

For production use, create a user in the Cloud Pak for Data web client to use for authentication, and decide which authentication mechanism to use.

To have the SDK manage the lifecycle of the token, use the username and password for that new user in your calls.
To manage the lifecycle of the token yourself, generate a token from that user's credentials. Call the POST /v1/authorize method to generate the token, and then pass the token in an Authorization header in your calls. You can see an example of the method on the Curl tab.

For more information, see the Get authorization token method of the Cloud Pak for Data API reference.

Don't use the bearer token that's displayed in the web client for the instance except during testing and development because that token does not expire.

To find your value for {url}, view the details for the service instance by clicking the name of the service in your list of instances in the Cloud Pak for Data web client.

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.assistant.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.

Because the Cloud Pak for Data bearer token is associated with a username, you can use the token for all CPD Watson services that are associated with the username.

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 Watson Assistant, 2021-11-27. In some cases, differences in earlier versions are noted in the descriptions of parameters and response models.

Error handling

Watson Assistant 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.

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 Watson Assistant 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}/v2/{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 = assistant.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

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

    var responseJson = reresponsesults.Response;  //  The raw response JSON
    var statusCode = response.StatusCode;         //  The response status code
}

Data labels (IBM Cloud)

You can remove data associated with a specific customer if you label the data with a customer ID when you send a request to the service.

Use the X-Watson-Metadata header to associate a customer ID with the data. By adding a customer ID to a request, you indicate that it contains data that belongs to that customer.

Specify a random or generic string for the customer ID. Do not include personal data, such as an email address. Pass the string customer_id={id} as the argument of the header.

Labeling data is used only by methods that accept customer data.
Use the Delete labeled data method to remove data that is associated with a customer ID.

Use this process of labeling and deleting data only when you want to remove the data that is associated with a single customer, not when you want to remove data for multiple customers. For more information about Watson Assistant and labeling data, see Information security.

For more information about how to pass headers, see Additional headers.

Data collection (IBM Cloud)

By default, Watson Assistant service instances managed on IBM Cloud that are not part of Enterprise 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 Enterprise plans.

To prevent IBM usage of your data for an API request, set the X-Watson-Learning-Opt-Out header parameter to true. You can also disable request logging at the account level. For more information, see Controlling request logging for Watson services.

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 with a service managed on IBM Cloud

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

Example request with a service managed on IBM Cloud

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

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

assistant.SetServiceUrl("{url}");

assistant.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 = assistant.method(parameters).execute();

Example asynchronous request

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

Example synchronous request

response = assistant.method_name(parameters)

or

response = assistant.await.method_name(parameters)

Example asynchronous request

response = assistant.async.method_name(parameters)

Pagination

Some API requests might return many results. To avoid performance issues, these results are returned one page at a time, with a limited number of results on each page. The starting point for each page of results is identified by a token called a cursor.

The default page size is 100 objects. To use a different page size, use the page_limit query parameterpage_limit parameterpageLimit parameterPageLimit parameter.

To change the attribute by which results are sorted, use the sort query parametersort parameterSort parameter. If you include multiple sortSort parameters on the same request, the results are sorted first by the first sorting attribute, then the second, and so on.

The supported sorting attributes vary by endpoint. For more information, see the API Reference information for each method.

For any request that uses pagination, the response includes a pagination object that specifies pagination information. This object includes two URLs that you can use to make subsequent requests:

refresh_url: The URL for requesting the same page of results again.
next_url: The URL for requesting the next page of results. The next_url property is omitted if no more results exist.

Each URL specifies the appropriate cursor parameter and retains the same page_limit and sort parameters that were used for the initial request.

For any request that uses pagination, the response includes a paginationPagination object that specifies pagination information. This object includes two cursor tokens, refreshCursorrefresh_cursorRefreshCursor and nextCursornext_cursorNextCursor, that you can specify on subsequent requests.

To request a specific page of results, specify the appropriate value by using the cursorCursor parameter. When you request subsequent pages, do not change the values of the sort and pageLimitsort and page_limitSort and PageLimit parameters (if any).

Rate limiting

Rate limits for API requests are enforced on a per-service-instance basis. If the number of requests for a particular method and endpoint reaches the request limit within the specified time window, no further requests are accepted until the timer expires. After the timer expires, a new time window begins with the next accepted request.

The response to each HTTP request includes headers you can use to determine whether you are close to the rate limit:

X-RateLimit-Reset: the time the current timer expires (in UNIX epoch time)
X-RateLimit-Remaining: the number of requests that remain in the current time window
X-RateLimit-Limit: the total number of requests allowed within the time window

An HTTP status code of 429 indicates that the rate limit has been exceeded.

The number of allowed requests, and the length of the time window, vary by method and endpoint. The reference information for each endpoint specifies the rate limit that applies.
