401 Unauthorized Error in Pega Service REST API
I am facing a 401 Unauthorized error when configuring a Service REST API in my Pega Trial environment. I have set up OAuth 2.0 with client credentials, created a service package with the correct authentication, and configured a GET method in the Service REST rule using an activity that fetches case data. Despite receiving a valid OAuth token, the GET request to fetch case data returns a 401 Unauthorized error. I have ensured that all rulesets and access groups are correctly configured. Can anyone provide insights on additional configurations or steps needed to authorize and process the GET request successfully?

A 401 error code in the context of a REST API in Pega indicates that the request is unauthorized. This typically means there is an issue with authentication. Here are the steps to troubleshoot and resolve this issue:
### 1. Verify Authentication Credentials Ensure that the credentials (username and password or token) being used for authentication are correct.
- **Basic Authentication**: If you are using Basic Authentication, make sure the base64 encoded username and password are correct. - **OAuth**: If you are using OAuth, ensure the access token is valid and not expired.
### 2. Check Authentication Configuration Confirm that the authentication method is properly configured in Pega.
- **Service Package**: Check the service package associated with your REST service to ensure it has the correct authentication type. - Navigate to `Records` > `Integration-Resources` > `Service Packages`. - Open the relevant service package and verify the authentication type (Basic, OAuth, etc.).
### 3. Verify Operator ID Configuration Ensure that the Operator ID used for the request has the correct access and is active.
- Go to `Records` > `Organization` > `Operator ID`. - Open the relevant Operator ID and check: - The status is set to `Active`. - The Operator ID has the necessary roles and privileges.

- Go to `Records` > `Organization` > `Operator ID`. - Open the relevant Operator ID and check: - The status is set to `Active`. - The Operator ID has the necessary roles and privileges.
### 4. Check Authentication Policy Review any authentication policies that might be affecting the request.
- Navigate to `Records` > `Security` > `Authentication Policy`. - Ensure there are no restrictive policies that would prevent authentication.
### 5. Verify Access Group Make sure the Operator ID’s access group has access to the necessary rulesets and REST services.
- Open the Operator ID record. - Check the Access Group field and open the access group. - Verify that the access group includes the necessary rulesets.
### 6. Inspect Network and Proxy Settings Check if there are any network issues or proxy settings that might be interfering with the authentication request.
- Ensure that the request is reaching the Pega server without being blocked or altered by a proxy or firewall.
### 7. Review Logs Examine Pega logs for any detailed error messages that can provide more insight into why the authentication is failing.
- Go to `Admin Studio` > `Logs` and review the relevant logs.
### 8. Test Using Postman or Curl Use a tool like Postman or curl to manually test the REST API with the same credentials and headers. This can help isolate whether the issue is with the client configuration or the server.
### 9. Update Security Settings (if applicable) If you are using an external authentication system, ensure that the configurations are updated and synchronized between Pega and the external system.
By following these steps, you should be able to identify and resolve the cause of the 401 error when using REST APIs in Pega. If the problem persists, you might need to consult the Pega support documentation or seek assistance from your Pega administrator.

@SeanW17188769 Based on the information you've provided, it seems like you've done the correct configurations. However, the 401 Unauthorized error might be due to an access issue. In a similar case, the issue was resolved by adding the sysadm4 access role to the access group of the service package. Please try this and see if it resolves your issue.

@SeanW17188769 The 401 error is an HTTP status code indicating the request sent to the website's server lacks valid authentication credentials. This means that the server understands the request but refuses to authorize it. Check authentication , Check operator record role access and also check which auth service you are utilising
