If you integrate nothing at all

You do not have to write code to accept a voucher. Two paths work today.

The link

When a holder taps use this voucher, we send them to the pricing page you registered with the listing, carrying the reservation:

https://yourapp.com/pricing?bm_ticket=…&bm_price=20.00&bm_product_key=plan.pro&bm_months=1

Read it in one line:

import { readTicket } from '@bullmark/sdk';
const ticket = readTicket(location.search);

You now know somebody arrived holding a voucher and what it is worth. Even if you do nothing with it, that is more than an untracked coupon code would have told you — and when you are ready, redeem({ ticket, externalRef }) is the only line you add.

Note

The ticket is a secret: it is what confirms the burn. It reaches the holder and reaches you; do not log it anywhere a third party reads.

The screen we host

Sign in at bullmark.net → Redeem a Voucher. Type the code a customer is showing you and you get the price, the term and your own product key. Give them that price, enter your order number, confirm.

This is the same canon as the API — a redemption made here is indistinguishable, on the chain, from one made by your server.
