Comparison of IBM Cloudant and Apache CouchDB API endpoints

The IBM® Cloudant® for IBM Cloud® and Apache CouchDB 3.x API endpoints, and the methods for accessing them, are described here.

The table shows you which endpoints are present in the CouchDB or IBM Cloudant service.

Some CouchDB endpoints don't have IBM Cloudant equivalents because it wouldn't be meaningful. Similarly, some IBM Cloudant endpoints don't have CouchDB equivalents.

While IBM Cloudant is API-compliant with CouchDB, IBM Cloudant doesn't support URL rewrites from the JavaScript function.
