Oauth for Api Tempo

Hi experts.

I´m trying to connct to Tempo to get all workslogs through REST API.

As I understand it, I need to get a token, so I have in my Administration created a Oauth 2.0 application.

As I understands the guide, I need to go to


Filling out the correct “MYSITE” and “CLIENTID” and into a browser to get an token - all I get is “Something went wrong”-message

Using same URL in Postman GET, gets me a 28000 line document back with all kinds og stuff.

Can somebody please help me get to the next step, which I believe is to get an temporary Token (please correct me if i´m wrong)
