OTA endpoints

The OTA API provides a standardized set of endpoints for online travel agency (OTA) partners to list activities, check availability, and create bookings in Sailia. Use these endpoints to build integrations that sell a Sailia operator’s activities on your own platform. All endpoints require an API key with OTA permissions. See authentication for details on passing your key.

Bookings created through the OTA API are recorded with the OTA partner’s payment reference. The operator sees these bookings in their bookings dashboard alongside online and POS bookings.

Typical integration flow

A standard OTA integration follows these steps:

Discover products

Call list products to retrieve the operator’s activities. Cache results and refresh periodically.

Check availability

When a customer selects an activity, call get available dates to show bookable dates, then get available timeslots for the chosen date.

Collect waiver responses

Call get waiver questions and display the required fields to the customer before checkout.

Create the booking

Submit the reservation with create a booking. Handle a 409 response by prompting the customer to choose a different timeslot.

Error handling

All error responses follow the RFC 7807 problem detail format. See error format for details.

Status	Cause
400	Invalid path parameter — check the `ActivityID` format
404	Product not found
409	Insufficient capacity for the requested booking
422	Missing or invalid query parameters
