Keep Getting 401 response using a valid token

Ask the Experts and Postman Tips

Hi! I am currently testing my API endpoint with an Authorization header. It is working fine during my previous tests but since yesterday I started getting 401 responses. I am using a valid token.

I already tried putting it in the Authorization tab and in the Headers but the same response.

Hey @JBGodilo! Welcome to the community :wave:

I understand you started to receive 401 response although the token is still valid.

Can you tell me a few things to understand the issue precisely?

  • Is this API service public or private? - If it’s in-house API, is there any recent updates on the backend server that might be causing this?
  • Do you see the error when you send a request from outside of Postman (e.g. cURL command in the terminal)?

I am looking forward to hearing back from you :smiley:
