Ponch is a digital loyalty stamp card platform. Merchants design a stamp card, customers add it to Apple Wallet or Google Wallet, and staff stamp it at the counter. The Ponch API lets another system do the same things and hear about them as they happen:
It's a plain JSON-over-HTTPS REST API authenticated with a bearer API key. The Ponch apps for Zapier and Make are built on it, and anything they do you can do directly.

Every path in these docs is relative to that base. For example,
GET /integrations/me means GET https://app.getponch.com/api/integrations/me.
In the Ponch dashboard, go to Integrations → API keys, enter a label and click Create key. Copy the key now: it is shown only once. See Authentication.
Check the key:
curl https://app.getponch.com/api/integrations/me \
-H "Authorization: Bearer $PONCH_API_KEY" \
-H "Accept-Language: en"
{
"company": {"id": "3f1c2a9e-5b7d-4c11-9a2e-6d0b8f4e7a21", "name": "Luna Coffee", "slug": "luna-coffee"},
"merchant": {"id": "6a8c0e2a-4c6e-4a8c-b0e2-4a6c8e0a2c5d", "slug": "luna-coffee"},
"plan": {"slug": "growth", "name": "Growth"},
"api_enabled": true,
"store_count": 1,
"active_template_count": 1
}
Add a stamp to a card by its barcode (the SC-… code on the pass):
curl https://app.getponch.com/api/stamping/stamp \
-H "Authorization: Bearer $PONCH_API_KEY" \
-H "Accept-Language: en" \
-H "Content-Type: application/json" \
-d '{"barcode_value": "SC-1540CD2A802A", "source": "api", "idempotency_key": "order-10482"}'
The customer's wallet pass updates within seconds.
