OAuth 2.0 with Client Credentials not working

[codedog]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

I am trying to do OAuth with Client Credentials in Bruno, basically the equivalent of this Postman setup.

It works in Postman but I'm getting an error in Bruno. I can't see the actual request sent out by Bruno, and I'm not sure how I go about diagnosing this issue.

.bru file to reproduce the bug

No response

Screenshots/Live demo link

I have included screenshots in the description above.

Client ID, secret and access token URL are required fields, you skipped it only for privacy, or you actually did not configure it?

Does it work in Postman if you select client authentication to send in Request body instead of Basic Auth header (possibly the cause, as Bruno uses the latter)?

Yes, I configured those values but censored them in the screenshot.

The docs for this particular API mentions Basic Auth header, and it works. I haven't tried sending it in the body. What does the body content look like in Bruno's case? I can try it when I get back to the office.

It really is hard to explain in a few words, look at #1999.

Also sending token in Basic Auth header in Bruno is not yet implemented: #2106

I tried sending client credentials in the body in Postman, and it failed.

That sounds about right, and it looks like you may have to wait for #2106 - which was promised to be delivered during this month. You may try running from the branch behind the link, and it hopefully works for you.
