Scriptrunner - JIRA REST Endpoint to download attchments.

[Abin Jacob]

Currently, there are no rest APIs available to download a Jira attachment. Can somebody explain me how to create a custom rest endpoint to download an attachment by calling the rest call and giving the parameters issue id and attachment id?

Welcome to the Atlassian Community!

You can use the "get content" REST call to get the attachment - see https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-attachments/#api-group-issue-attachments but you do need to do a bit of messing around to get the file name and work out what the attachment id is (you'll need to do that messing around in a REST endpoint too)
