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

Question

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!

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

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?

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/
