Retrieve Parameters Using a REST API Request

You can use a REST API request to retrieve and view customizable parameters and their current values. Your account settings determine the values you can view for a portfolio, merchant, or transacting merchant ID (MID).

You must authenticate each request that you send to a Visa Acceptance Solutions API. In order to authenticate an API request, you can use a REST shared secret key or a REST certificate. For more information about authentication requirements, see

Getting Started with REST

.

Endpoints

The GET request must include the organization ID for the portfolio, merchant, or transacting merchant ID that is sending the request.

Test:

GET https://apitest.visaacceptance.com/dms/v2/customization?type=organization&id={{organization id}}

Production:

GET https://api.visaacceptance.com/dms/v2/customization?type=organization&id={{organization id}}
