    {
      "errorCode": 4,

      "errorReason": "INVALID_PARAMETERS"
    }

Audit trail tracks all activities performed in the Mambu Core Banking system via the UI or API v1 and v2. For more information, see Audit Trail in our User Guide.

When the audit trail feature is enabled, you must provide a User-Agent header for all requests to any endpoint, or the request will fail with the error message The user agent cannot be null when the Audit Trail feature is enabled.

Note that if you are using a REST client like Postman or Curl, this header is probably provided automatically. However, if you generate a request to the API, you must provide it yourself.

The User-Agent header provides information regarding the browser and operating system (such as the browser version), and information about the library or tool issuing the request (such as the client Java version). It is generally used to assist with debugging problems.
