Jira API returns 401 when fetching (some) project assignees

[Artiom Petrov]

Hello,

I'm trying to perform integration with Jira API (using basic authentication) to get all project assignees.

I'm addressing the following URL:

https://<jira_url>/rest/api/2/user/assignable/search?project={PROJECT_KEY}

For most of the projects I do get the assignees, but for some, for an unknown reason, I'm getting 401 unauthorized.

My guess is that the credentials I'm using don't have enough permissions for all projects.

So my questions are:

1. Is the permissions issue can possibly happen?

2. If yes, how can I reproduce this in my Jira account (how can I give permissions to some users for certain Projects)?

Thanks in advance!

1. Yes, it could be the permission issue

2. Login to the box, using the same credentials, and check if you have "Create" and "Assign" permissions in the projects where it is failing. If not, you will have to work with those project admins to grant you the access.

Thanks!

I think It has something to do with the permissions of "Assign Issues". I removed my user's permission to assign issues, then got 401 for this project.

Correct. You need the 'Assign' issue permission to retrieve the list of potential assignees.
