Getting started with the Rex API
The Rex API lets you build custom integrations, pull reservation data into your own systems, and automate venue management tasks.
Base URL
https://yourvenue.reservewithrex.com/api
Authentication
The API uses Bearer token authentication. Include your API key in every request: Authorization: Bearer YOUR_API_KEY
Key endpoints
GET /api/reservations — list reservations
GET /api/reservations/:id — get a single reservation
POST /api/reservations — create a reservation
PATCH /api/reservations/:id — update a reservation
GET /api/packages — list available packages
GET /api/availability — check availability for a date range
Generate and manage API keys
API keys allow external systems and developers to access your Rex data programmatically. Manage your keys under Settings > API.
Go to API Settings
In the sidebar, navigate to Settings > API.
View existing keys
The API page lists all active API keys with their name, creation date, and last used date.
Generate a new key
Click "Generate API Key" or "Create Key". Enter a descriptive name for the key (e.g. "Zapier Integration", "Custom POS Connector").
Copy the key
The key is displayed once after creation. Copy it immediately and store it securely — it will not be shown again in full.
Use the key
Include the API key in the Authorization header of API requests: Authorization: Bearer {your-api-key}
Revoke a key
To revoke access, find the key in the list and click "Delete" or "Revoke". The key is invalidated immediately.
