Cross-Origin Issue with Jira Cloud API: Nginx Reverse Proxy Not Working

[chenhui Hu]

Hello,

I am trying to call the REST API rest/api/3/user/search?query=${email} from the front-end, but I am encountering cross-origin issues. I've attempted to use an Nginx reverse proxy for Jira Cloud, but I'm getting a 404 response.

Is it possible to use an Nginx reverse proxy with Jira Cloud? If not, what other solutions are available to solve cross-origin issues apart from using a reverse proxy?

Thank you for your help!

You can't just put a reverse proxy before Jira.  This won't work.

However you can proxy API requests through a proxy.  For this to work, you'd need to sort out an authentication method for the proxy.  One possibility might be Basic Auth: https://developer.atlassian.com/cloud/jira/platform/basic-auth-for-rest-apis/

My frontend is currently accessing the Nginx proxy server, which then forwards requests to Jira using the api token, but it's not working.

Could you please explain the difference between placing a reverse proxy in front of Jira and using a proxy to forward API requests?

A reverse proxy in front of Jira will proxy all http traffic, whereas an API proxy will only proxy the individual API calls.
