REST API Error: "User is not authenticated" - Required to provide Auth information

[SivaPrasadR3900]

We are encountering the following error while making a REST API call:

{

"error": {

"message": "User is not authenticated",

"detail": "Required to provide Auth information"

}

"status": "failure"

}

We have already configured the service account with the following roles:

• snc_internal
• rest_api_explorer

Additionally, on the User record:

• Identity Type is set to Machine
• Integration User is set to True

Despite these configurations, the API call is still returning the authentication error.

Could anyone advise:

• Whether additional roles are required for integration users?
• Whether the Identity Type or Integration User settings could be affecting authentication?
• What logs or troubleshooting steps should be checked to determine why the authentication information is not being recognized?

Any guidance would be appreciated.

Thanks

hi @SivaPrasadR3900 ,

Are you using Basic Auth or OAuth?.

For reference :

OAuth Access Token is Valid but API Returns HTTP 401

what type of authentication is being used?

which API you are hitting? OOTB Table API or Scripted REST API?
