Klook
Klook is a Hong Kong-headquartered travel and experiences booking platform for the "things to do" sector — attractions, tours and activities, theme parks, food and beverage, WiFi and SIM cards, and transportation passes. Klook publishes an Open API specification for merchants, suppliers, reservation systems and channel managers who want to distribute their inventory through Klook's website, app and partner channels. The specification is an implementation of OCTO (Open Connectivity for Tours, Activities and Attractions), the open standard for the in-destination experiences industry: the supplier implements the OCTO core endpoints (Supplier, Products, Availability, Bookings) at their own host and Klook consumes them as the reseller, with optional Capabilities negotiated through the Octo-Capabilities header. Klook additionally runs an affiliate program and a merchant portal.
Klook publishes 1 API on the APIs.io network: Open API (OCTO). Tagged areas include Company, Marketplaces, Travel, Tours and Activities, and Booking.
The Klook catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Klook’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, authentication, changelog, and 21 more developer resources.
