Using Snapplify Voucher API

This guide describes how to use the Snapplify Voucher API to generate vouchers for users to redeem and gain access to Snapplify content.

Vouchers are used to manage the sale of Snapplify products through a third party. Once a voucher is redeemed, the customer receives their digital product, referred to as an ‘entitlement’.

Voucher API provides an interface for programmatically adding vouchers into the Snapplify administration system, and for users to redeem these vouchers (including querying these for verification upon redemption, etc.).

This enables you to provide voucher codes to users following content sales, and facilitates the rollout of digital content in bulk to academic institutions and other organisations.
