Read and content integrations need no approval; booking writes require a Sherpa Agency contract via sales. The only official SDK is Python, and there is no OpenAPI spec.

G Adventures is a Toronto-headquartered small-group adventure tour operator founded in 1990 by Bruce Poon Tip, marketing itself as 'The leader in small group travel for over 30 years.' Since the 2021 Certares private-equity investment and a subsequent buy-out and 2023 restructure, the company sits inside the G Travel Community (GTC) holding company alongside TruTravels (acquired 2018, UK youth/backpacker brand), and the G Touring umbrella covering Travelsphere and Just You (both acquired 2017, UK guided and solo-traveler brands).
Vertical: misc (consumer leisure travel / adventure tour operator). No Sanity vertical maps cleanly; weak adjacency to POS/Hospitality (inventory/reservations) and Travel & Expense (T&E is corporate spend, G Adventures is leisure). A consumer browses tours on gadventures.com (or one of the GTC sister brand sites), books with a deposit, and travels with a small group led by a G Adventures Chief Experience Officer; G Adventures is the operator-of-record end-to-end.
7/10 as a consumer adventure brand; 4/10 as a developer platform. In multi-day small-group adventure travel, G Adventures sits at or near the top of the category alongside Intrepid Travel, the two are routinely paired as 'the' small-group adventure operators of record.
For G Adventures itself: full traveler PII (name, DOB, passport, dietary/medical needs, emergency contacts), payment records and deposit ledgers, departure manifests, Chief Experience Officer assignments, on-trip incident logs, supplier/DMC contracts, agency-channel commission records, and the internal reservation/operations system of record (G Adventures has not publicly disclosed whether it runs on a Kaptio-class third-party reservation platform or on home-grown infrastructure; the long-lived gapipy SDK and bespoke REST contract suggest substantial in-house build).
Founded 1990 in Toronto by Bruce Poon Tip, 36 years old as of 2026. Consumer site (gadventures.com) is modern, content-heavy, mobile-responsive, with sophisticated trip search/filter and progressive deposit/booking flows.
No public OpenAPI/Swagger specification, partners must hand-code request/response shapes from prose docs or rely on the Python SDK as the de-facto schema reference. Specific rate-limit quotas are not published, partners learn ceilings only by hitting HTTP 429 in production, with no documented backoff guidance or quota-increase process.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
