The Clarabridge Engage API only allows clients to make a limited number of calls in a given hour. This policy affects the APIs in different ways.
The default rate limit for calls to the REST API varies depending on the authorization method being used and whether the method itself requires authentication.
In general, these rate limits are applied to methods that request information, update and/or delete information. To be sure about the exact rate limits, read the information from the API Response's HTTP Headers (see below).
We reserve the right to adjust these rate limits subject to fair use limits.
WARNING The rate limits of tokens from the API Console are lower (20 authenticated calls per hour instead of 350 calls per hour) than the default for other API Clients. Please register your own API Client for production use.
For rate limited API calls, extra information is included in the http headers of the response.
If your application is being rate-limited by the API it will receive HTTP 400 response codes and the content of the response will be an error with value "rate_limit_reached". It is best practice for applications to monitor their current rate limit status and dynamically throttle requests if necessary. (See above.)
API Rate Limit Whitelisting is not provided. Resourceful use of more efficient requests will allow you to build your integration successfully without requiring whitelisting.
Store API responses in your application or on your site if you expect a lot of use. For example, don't try to call the API on every page load of your website landing page. Instead, call the API infrequently and load the response into a local cache. When users hit your website load the cached version of the results.
If your site keeps track of many Clarabridge Engage users, consider only requesting data for users who have recently signed into your site.
