Build with Hyperspend
Two small JSON APIs: one for merchants who accept vouchers, one for distributors who sell them. Both come with test keys and a sandbox, so you can build everything before going live.
Accept vouchers
Merchant API →
Accept Hyperspend vouchers at your checkout or as an account top-up: check a PIN, redeem it, credit the customer.

Sell vouchers
Distributor API →
Sell Hyperspend vouchers on your platform: issue a voucher when your customer pays, and hand them the PIN instantly.

Test first
Every partner gets a test key. Merchants get fixed sandbox PINs; distributors issue sandbox vouchers. Nothing touches real vouchers or money.
Safe retries
Send an Idempotency-Key and retry freely after a timeout. A voucher is never redeemed or issued twice.
