Quick start

Up and running in minutes

The GxP API uses standard HTTP methods, JSON request/response bodies, and bearer-token authentication.

1. Authenticate — Get a token via Sanctum or an API key
2. Explore the API — Browse endpoints in the interactive reference
3. Subscribe to events — Stream real-time updates over WebSockets
4. Configure webhooks — Receive notifications when data changes

curl -X POST "https://api.gramercy.cloud/api/v1/attendees" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "first_name": "John",
    "last_name": "Doe",
    "email": "john.doe@example.com",
    "attendee_type_id": 1
  }'
