How to Go Live

Once you have tested your application in our sandbox environment, you can begin the process to go live.

  • First, create a new App for production. 
  • To gain production access, it is important that both your account and App details are registered correctly:
    • Browse and Subscribe to the API Products you intend to leverage in the production environment.
  • Once you've subscribed to your desired API Products, your request will be placed in queue.
  • Depending on the API, our API Services team might contact you to discuss the details of your request.
  • Be sure to include the following in your request:
    • Name of Application
    • List of Domains and Endpoints being requested
  • Once approved, you are ready to use our API in a live environment.


APIs use OAuth2 for authentication, authorization, and identification. To obtain an access token, you need to call our OAuth API. The authentication mechanism can vary per API depending on the required level of authentication. Please browse the API Catalog for more information and the API specifications.
