JSM API - Oauth2 and service-to-service

[Frederik Krogh]

Hi,

I am new to JSM and trying to do som sync and automation with Jira and our other systems.

It might be because I am trying out Atlassian Access but when I try to authenticate with the base64 API key, I get the error that basic auth is deprecated. Okay fair enough Oauth is better and more secure.

However the access code flow does not support service-to-service.

How have you guys tackled this?

Hm, from what I know Basic Auth with Password is deprecated but Basic auth with an api key should still work, I usually get the deprecation message when there is an error in the header (specificly the b64 part or the keyword). Did you just provide the b64 API key or did you provide the b64ed email:apiKey string? I've also seen people use the Bearer keyword rather than the Basic keyword. In full you should have something along the lines of:

Authorization: Basic {b64(userEmail:apiKey)}

Hope this helps. Feel free to let me know if you run into any problems.

Greetings 
Gideon

You were absolutely right. I fu**ed up the header. Thanks!

No problem - been there done that and also saw way to many people throw the towel at this exact point. It's a common problem with an absolutely unhelpful error message.
