REST API · v1

API reference.

Base URL: https://api.passmint.com

Authentication

Pass your API key as a Bearer token in the Authorization header. Test keys use the pmk_test_ prefix and live keys use pmk_live_. The mode (test or live) is determined by the key prefix.

Authorization: Bearer pmk_test_xxx

Idempotency

Send an Idempotency-Key header on POST and PATCH requests to safely retry without duplicating side effects. Replays within 24 hours return the cached response. Reusing a key with a different request body returns 409.

Idempotency-Key: 7c9e6679-7425-40de-944b-e07fc1f90ae7

Response format

Single objects include an object field identifying the type. List endpoints wrap results in a standard envelope.

// Single object
{
  "object": "pass",
  "id": "pass_xxx",
  ...
}

// List
{
  "object": "list",
  "data": [...],
  "has_more": false
}

    "type": "invalid_request_error",
    "code": null,
