Each organisation has the following limits in place when utilising the Sessions API:

  • No more than 20 requests per second
  • No more than 100 concurrent requests
  • No more than 10,000 requests per month

If any of these limits are reached, the API will return an error like so:

429 Too Many Requests

There are lots of ways to ensure that the above limits aren’t reached, but an easy way to get started is to wait for a short amount of time and then retry the request.

A more advanced option is to automatically retry the operation with a backoff. Here is an example of how this can be done in Python.

If you find you are reaching this limit a lot, then please reach out to your account manager and let them know.
