Getting 401 with newly created API key


I have created my app and my API key today and I only get 401 {“message”:“Invalid authentication credentials”}.
I am using postman and the “Try out” button on the website, my TRN-Api-Key is correctly passed as a header but 401.
Is there an extra step I missed that I need to do to gain access?

Thank you

I’m having this same issue. This is the second time I’ve tried using their API and been unable to after following the docs. Dunno why their API is so difficult to use.

I’ve tried using the “Try it out” button and curl, both with the same error.

I guess there are only a few people working there.
I have joined the discord and asked for help there.
There seems to be one person helping others in the same situation.
