API access Issues

Can someone help me figure out why I am receiving the following error when I try to log in with Postman.

{
    "code": "gform_rest_authentication_error",
    "message": "Invalid signature - provided signature does not match.",
    "data": {
        "status": 401
    }
}
  • WP > Forms > Rest API Settings > Enabled
  • Authentication API version 2 > created a key
  • copy and pasted the keys into env variables in Postman (confirmed they are same values as keys in Rest API Settings.
  • Postman url: GET: https:///wp-json/gf/v2/
  • Postman > Params > oauth_signature > value is present (auto generated)
  • Postman > Params > oauth_signature_method > HMAC-SHA1
  • Postman > Params > oauth_version > 1.0

I tried turning on the logging feature in WP > Forms > Settings and I did not find any further information then the error code above.

I have been looking on YouTube / Gravity Docs / Stack Overflow and have not been able to find any solutions.

Thank you for any help you you can provide.
