I have been paper trading for some time now using an app I am testing.
Recently the app has been throwing an error having to do with the API key.
I updated the api keys thinking that was the issue and I still get errors.
So I tried using postman using new keys and I get this error:
"message": "request is not authorized"
What does it mean? Is this a technical error? A formatting error? An issue with my alpaca account? How do I fix this problem?
