Error code: 401 Unauthorized

Help! I’ve got a 401 error!

Trying to interact with one of your integrations in Lexer and receiving a 401 error? Firstly, don’t panic! This error is due to a lack of authentication, rather than authorization. What this means is that we’re unable to facilitate the requested action because there’s a lack of authentication credentials (logged in account) rather than a lack of authorization (account permissions).

This could be because:

  • You’re using an incorrect API key, causing the server to reject the authentication credentials.
  • The account you’re using has expired, or is deactivated.
  • You haven’t provided up-to-date authentication credentials.
  • The API key, or account, is missing permissions on the integrated service.

We have listed out a number of troubleshooting options for you to try below.

  • Double-check that you are using the correct API key that corresponds to your account.
  • Check that your account hasn’t been deactivated, or isn’t expired.
  • Check that the integrated account has the correct permissions.
  • Check that the IP address sending the data isn’t restricted in any way. It may need to be added to an “allow” list to send data.
