Button's DeepLink commerce gives developers the ability to link complimentary apps together in order to extend app functionalities across apps and drive adoption by increasing downloads. For server-side integrations, Button offers a RESTful Loyalty API that can help track cross-app commerce and insert promotions into apps in order to increase customer loyalty. In order to process API requests, developers must acquire a partner ID and partner secret for access. With HTTP POST and GET requests, the Button API can be programmatically evoked to create and manage users, retrieve user point balances, manage user points in accordance with loyalty rewards, move reward balances, and more. Button offers staging and production API environments for testing and publishing, respectively.
