API Rate Limits
To protect our infrastructure and ensure resource availability for all users, a rate limit of 100 calls over a 1 minute period has been implemented. Automations triggered via the API after this limit has been reached will not run, and this will not appear in your run reports. We recommend that you limit calls in the application that you are triggering your automations from to prevent failures.
Exceeding this limit will return a 429: Too Many Requests error and your automation will not run.
