Concurrent Request Limit

The concurrent API request limit defines the maximum number of parallel API requests that can be processed simultaneously. The concurrency limits are defined per user account for each API.

The following table lists the maximum number of concurrent requests allowed per user account for an API. On exceeding the concurrency limit, the API returns the HTTP 429 error code with the Too many concurrent requests error message.
