New load-balance mechanism for integrations

Clinical One Cloud Service now uses API throttling, which is a rate-limiting approach to manage API request volume. It controls high volumes of external API traffic to help maintain consistent Clinical One Cloud Service performance.

Throttling is only applied to external requests and only if the defined limits are exceeded. This helps ensure the Clinical One Cloud Service operations function without interruption for a steady user experience. While using integrations, if the limits for external API requests are exceeded, you get a 429 - Too Many Requests error response. This response also provides the details on when to retry the request.

As part of Clinical One Cloud Service 26.2, throttling is implemented for the following API categories:

• Data Hub
• Data Integration
• Randomization and Supplies

Other API categories will be included as part of a future release.

You can find additional information in the REST API for Clinical One Cloud Service guide, after the assessment environment upgrade completes.
