Airships APIs allows partners (typically POS) to; * Create unique code groups * Check the status of a voucher code * Redeem a voucher code Vouchers are contained in Unique Code Groups - Which is a collection of vouchers for a single purpose - I.e. a specific offer might be for a 'Free cup of coffee' - in which case a Unique Code Group will be created for that offer and all the relevant vouchers generated within that group. When a partner attempts to check the status, or redeem a voucher code - The clients Account ID and Unique Code Group ID must be provided to Airship so the correct voucher is validated --- # Agent Instructions This documentation is published with GitBook.
