Connect your website to Opseno.

OpenAPI-documented HTTP API for restaurant sites, booking widgets, and partner systems. Same production API that powers the Opseno dashboard.

Open API reference Documentation

Create an API key

In the dashboard go to Settings → API keys. Copy the ops_live_… secret once - it is not shown again.

Call with Bearer auth

Send Authorization: Bearer ops_live_… on every request. For multi-property workspaces, add X-Baspex-Property-Id.

Book, sell, sync

Use availability, reservations, guests, and catalog endpoints from your restaurant site or partner app.

Quick example

Check live room availability for a date range, use the same endpoint your booking widget would call.

availability.sh

bash

curl -s \\
 'https://opseno.com/api/v1/pms/availability?arrival_date=2026-09-01&departure_date=2026-09-03' \\
 -H 'Authorization: Bearer ops_live_...' \\
