(PureBasic) CardConnect Validate Merchant-Level Credentials

To test and validate merchant-level credentials, you can make a PUT request, including the merchant ID in the body of the request, to the base URL. The Gateway verifies that the MID matches the credentials provided in the header.

Note: This example requires Chilkat v11.0.0 or greater.
