Is it possible to use OAuth to call the Service Management API without login redirect?

[Ruoyu Jiang]

We have an external API that integrates with Jira Service Management project. Currently we are using Basic auth for REST APIs but thinking to use OAuth instead.

As the API application runs automatically in the server, we are wondering if we can use OAuth without having to redirect the user to Jira to input credentials (like 2-legged OAuth).

My research showed me that it's not possible. But maybe some of you know better than me.

Best,
