3CX Integration Reponse 429

Develop, Build & Integrate APIs & Integrations

We have been using the standard 3CX integration method for over one year but since this morning we are receiving 429 TooManyRequestsException.
Nothing in the code changed. How is this possible?
We have no increase in activity and certainly do not 100 requests per minute or 250,000 per day.

The 429 TooManyRequestsException in 3CX usually occurs due to rate limiting, even if your request volume hasn’t increased. Possible causes:

  1. Server-Side Changes – 3CX may have updated their rate limits.
  2. IP Blocking – Your IP might be temporarily blocked due to repeated requests.
  3. API Misinterpretation – Some API endpoints may be stricter than others.
  4. Caching or Retry Mechanism – Ensure your integration isn’t unintentionally retrying failed requests.
  5. Contact 3CX Support – Verify if there are new restrictions or issues on their end.
