Xentral

The Xentral API is currently rate limited independent of the plan to 100 requests/minute (one request per 600ms).

Bursts of up to 300 simultaneous requests are accepted and processed as follows:

  • the first two requests are processed immediately
  • the following requests (up to 300 requests) will be queued and processed with a fixed rate of one request per 600ms (300 requests in a burst will take up to three minutes to get processed).
  • the response for the requests in a burst will be delayed until the request is processed.
The limits mentioned above are flagged as due to change. Please check the Xentral developer portal regularly for the latest values
