The API endpoint you are trying to use only supports Two-Way SSL authentication. Please ensure you are not using any other token type. Make sure you are using the credentials that are assigned to your Visa Offers Platform project (refer to screenshot below).
Also, when you create a test App in our sandbox you will receive test data in your App (refer to screenshots below). The test data for your Visa Developer application is available in the Dashboard under test data in the left navigation, this will ensure that you are using valid data that has been provisioned for specific scenarios. Sandbox data is limited to what is provided in the Test Data tables and is not integrated to the Visa Network and you cannot test real data in sandbox.
If the error persists, please provide the following information:
1. End Point 2. Request Header 3. Request Body 4. Response Header (include the x-correlation-id) 5. Response Body
Using SoapUI, you can find the x-correlation-id in the Raw Tab of the response header.
