Chargebee API limits

What happens when I reach the API limit?


There are no additional charges to use Chargebee's APIs, however, to ensure optimal app performance we regulate the API limits for TEST & LIVE sites as listed.

Listed below are the API rate limits for each Chargebee plan:

 Live site Test site  Live site  Test site 
 Starter 150 150Up to 150 simultaneous requests, of which GET requests should not exceed 50 and POST requests should not exceed 100.Up to 100 simultaneous requests, of which the GET and POST requests must not exceed 50 each.
 Enterprise 500 

  • For TEST site on exceeding the limit all request will be blocked. The block will be removed automatically once they fall within limits.
  • For LIVE site on exceeding this limit
    • Your account will be flagged
    • You will be notified by email, (Owner, Admin & Emergency contact).
    • If we do not receive an acknowledgement all GET requests will be blocked, POST requests will not be accepted until we see fit.
    • Block will be removed after requests are throttled with specified limits.

If you have a scheduled activity and need a temporary API limit increase or looking to increase your default API limit, you can reach out to Chargebee support.

API Rate Limits

Chargebee restricts API requests when you exceed the limits entitled for your plan. The limiting mechanism is employed considering two criteria:

  • Requests per minute - Number of requests in the past 60 seconds.

  • Concurrent requests - Number of requests at an instance of time.

When the upper limit is breached on either of the above criteria, an HTTP 429 error response is returned for subsequent requests. As a result, no more requests are served until the limit resets (in approximately a minute).

If you need a temporary increase in the API rate limit, you can contact support@chargebee.com to avail it. Further, if you breach the limit frequently, we suggest you move to a higher plan (see table above) to accommodate the volume of requests.
