An HTTP 403 Forbidden response indicates that the server understood the request but refuses to authorize the requested operation. In a SOAR asset integration, this strongly points to an authorization or permissions problem involving the credentials configured for that asset. Therefore, asset credentials lacking adequate permissions is the appropriate answer.

This should be distinguished from authentication failures. Incorrect credentials commonly result in an HTTP 401 Unauthorized response, while a nonexistent REST resource more commonly produces 404 Not Found . A requirement for a different authentication mechanism, such as an API token, can ultimately cause authentication problems, but the question specifically associates the observed response with permissions.

For SOAR integrations, the service account should have the minimum privileges required for the actions performed by playbooks. For example, a read-only account may successfully retrieve endpoint information but receive 403 when a playbook attempts an administrative operation such as quarantining a host or blocking an indicator.
