Jira API: Issue custom field values (apps) payload size?

Forge
1

Hello,

I want to use the POST /rest/api/3/app/field/value Jira API to update multiple issues and multiple custom fields.

I’m currently using this API to make a separate call for each issue id.

Does anyone know, is there a size limitation to the payload I can send to the Update custom fields Jira API?

How many issues can I update at once, 10, 100, 1000?

Thanks.

Hello @Kuthair

As per the Bulk Operations APIs FAQs, the total number of issues you can bulk update in any one request is still the same 1,000 issue limit as it’s always been, but as to whether there is a limit on how many (quantity) custom fields can be updated per each of those issues, or if the request payload itself has a size (capacity) limit, I don’t think either of those is documented.

Why not just do some experiments yourself and find out? Then report the outcome back here so that we can all know the answer.

Ah.. thank you for the link, I did not know about the bulk operation API limit. I wasn’t looking for a hard limit necessarily, I just want to make sure my calls won’t fail. Based on this, I’m thinking I’ll chunk the calls into 100 issues each. It would’ve been nice if the docs referred to this.

Thanks again!
