Limits for REST API Calls under Cloud

[Alex Cumberland]

Trying to find out what are the limits on REST API Calls.   How many calls are aloud for a client over each day.    For example are the number of Rest API Calls limited to 5000 calls per day before being blocked.

Hello @Alex Cumberland 

Refer to this documentation:

Rate Limiting

 I did read that before and there was no specific number of calls mentioned where it will be blocked.  

It mentions in the "Scaling by users" section a "App" cost budget = 10 calls per second but not that is the actual limit just an example assumptions.

Thing is right now we have Jira Data Center and we have written some in house processes that are not apps like in the Marketplace but they generate reports and and they keep Jira in sync with other systems using REST API calls.   Some are automated and run on a schedule for management all through out the day.  But if say we have a limit of 5000 rest api calls regardless of where it comes from then we will have an issue if we have to go to cloud with out rewrites of our processes and how we keep various systems in sync.

A previous version of the documentation said:

REST API rate limits are not published because the computation logic is evolving continuously to maximize reliability and performance for customers.

That text was part of the document in 2023, but is not there now.

I have found a variety of post that say there are not publicly published hard limits for REST API calls, such as this one:

I also found this 2022 post:

Based on the documentation there is not a single hard limit for REST API calls. It sounds like it is calculated dynamically. But this is not an area of expertise for me, so I hope that another member will provide you with a clearer answer.

Alternately you can try contacting Atlassian Support to see if your can get authoritative information directly from them. If you go that route it would be great if you share here what you learn.
