Issue cards from your own software
Generate a personal wallet card link for any customer in your system. Deliver it through your own email, SMS, push, or in-app flow. The customer opens the link and saves the card to Apple Wallet or Google Wallet.
Developer integration
7stamp REST API
AvailableThe 7stamp REST API gives you full programmatic control over wallet loyalty cards. Issue cards from your own system, credit stamps from any trigger, create and assign vouchers to specific customers, and pull analytics from your code.
Use the API when you need to integrate 7stamp into a proprietary POS system, an accounting platform, a mobile app, or a website that no off-the-shelf integration covers. Zapier and Make handle the common stack. The REST API handles everything else.
What you can do with the API
The API is the write side of the integration stack. Use it whenever your own software should stay the operational source of truth while 7stamp handles the wallet loyalty layer.
Credit stamps from any source
When a purchase closes in your custom POS, when an online order is paid on your website, or when a service is completed in your booking system, call the API to credit stamps. The card updates within seconds.
Manage vouchers and campaigns
Issue a one-off voucher to a specific customer, create campaign-ready reward flows, and pull voucher status back into the systems that handle finance and service quality.
Typical scenarios
Proprietary POS or cash register
A restaurant chain runs an in-house POS that no marketplace integration supports. The 7stamp API is called from the checkout layer: every closed check triggers add-stamp logic and every redemption closes the voucher. From the cashier side, loyalty looks native.
Custom website or web ordering
An online shop wants loyalty for delivery orders. The 7stamp API is called from the checkout flow: when the order is placed, the customer gets a wallet card link in the confirmation and stamps are credited automatically.
Accounting or ERP reconciliation
An accounting team needs voucher redemptions matched against fiscal receipts. The API pulls voucher status and redemption metadata into the ERP for a cleaner monthly close.
Documentation
Detailed endpoint reference, request and response schemas, and code examples in cURL, Python, JavaScript, and PHP are available in the developer portal. The public developer portal link is being confirmed with product ownership, so contact us for access in the meantime.
Authentication
The API uses API keys with the prefix 7loc_sc_. Each key is bound to a specific Staff Login and scoped to a single location. Generate keys in admin.7stamp.com -> Stamp Cards -> API & Integrations -> API Keys. Keys can be rotated and revoked at any time.
Frequently asked questions
When should I use the REST API instead of Zapier or Make?
Use the REST API when you have a proprietary system, need total control, or want loyalty actions to happen inside your own backend instead of a no-code layer.
Can I add stamps from a website or delivery checkout?
Yes. Any system that can call HTTPS endpoints can issue cards, add stamps, or create vouchers through the API.
How are API keys scoped?
Each API key is tied to a Staff Login and a single location so access can be rotated, audited, and revoked safely.
