Increase file upload limit for APIs

I use NativeForms as a front end for a variety of purposes, and the forms integrate with Jira through, I presume, an API.   When a form is completed, and user selects  submit, an epic is created in Jira, triggering automation scripts.  Generally if a user uploads an image or other file in nativeforms, then those files are attached automatically to the Jira epic.

The problem I've encountered is related to the file upload.  Apparently Jira has a hard limit on the size of files that can be uploaded.  That is, if the summed, collective size of files uploaded to a nativeform is greater than 5 MB, then NONE of the files will automatically be attached to the Jira epic.  That means i have to do that step manually, which i don't want to do.

Question:  Is there a way to increase the limit for the file uploads?  I know the limit through empirical testing, but I've not seen a control for it in Jira settings, nor have I seen one described online.  

Thanks for your help!

Hi @Jim Ralston ,

there is a specific setting for attachment size limit. Please take a look here

Hope this helps,


Thanks much for your feedback.  I am familiar with that setting, but I think it may be for manual use of the UI on Jira app, and maybe not for automated issue creation by API. Please see attached for current settings, which shows about 2GB attachment size, which is orders of magnitude larger than the limits I've observed (~ 5MB summed across all attachments for single, automatically-created epic in Jira) Screen Shot 2023-04-17 at 11.29.04 AM.png

Are you aware of a separate setting for attachment size when attached via API for  automatically created issue? 


btw here is link to the nativeform which is at issue, though we seen this restriction with other similar nativeforms:
