What integrating TravelgateX into your platform solves
Access to multiple accommodation and activities suppliers without building a separate integration for each one.
Normalization of availability, rates, and booking flows across suppliers with different formats and protocols.
A single API to search, quote, book, and cancel — regardless of which supplier the inventory comes from.
Reduced maintenance: when a supplier updates their protocol, TravelgateX handles the adaptation on their side.
How the technical booking flow works
TravelgateX exposes its functionality through a GraphQL API. A typical accommodation booking follows these stages:
Search: availability and rates are queried for a given destination, dates, and occupancy across all active suppliers.
Quote: before confirming, the selected rate is re-validated to ensure it is still available at the same price.
Book: the reservation is created in the supplier's system and a booking reference is received.
Cancel: when needed, the reservation is cancelled and the response from the supplier is handled.
The integration work involves building an internal service that translates your booking engine's search and reservation requests into TravelgateX GraphQL queries, handles responses (including errors and availability changes), and maps data to your own domain model.
Critical points to resolve during integration
Availability cache management: search results expire quickly, and not all suppliers tolerate the same volume of repeated queries. A caching layer with appropriate TTL is essential.
Price difference handling between Search and Quote: the price can change between the initial search and the moment of booking confirmation. The UI must handle this case explicitly.
Supplier-specific error mapping: each plugin may return different error codes and formats. A unified error model for your system needs to account for these variations.
Cancellation policies: each supplier returns its own structure for deadlines and penalties. Parsing and presenting these to the end user clearly is critical.
Markup and commission logic: the price returned by TravelgateX is the net cost. The commercial logic for applying margins must live in your own system.
Common mistakes when integrating TravelgateX
Not caching search results, generating unnecessary query volume against suppliers.
Not handling the price difference between Search and Quote, causing booking errors or price mismatches.
Treating all supplier errors the same way, hiding useful debugging information in production.
Not defining in advance which plugins (suppliers) to activate in the first phase, leading to scope creep during development.
Skipping the reconciliation process between booked reservations and supplier confirmations.
What you need before starting the project
A TravelgateX account with API access credentials.
A defined catalog of the suppliers (plugins) to activate in the first phase.
Defined business rules for markup, commissions, and currency conversion.
A clear architecture for where the integration service will sit within your current infrastructure.
A test environment to validate flows against supplier sandboxes before going live.
At Granweb we integrate TravelgateX and other travel providers (Expedia, Hotelbeds, and others) directly into custom booking engines, including the architecture of the integration service, caching, error handling, and connection to your back-office and payment systems.
