Checkfront API

Tours, Activities & Rentals Booking / Reservation Management · checkfront.com

Checkfront publishes a public REST API: v3 is documented in detail while v4 slowly takes over. Access is gated, though: no trial-account keys, API access is purchased through sales, and OAuth2 app registration goes through partnerships. Rate limits are 429s with unpublished thresholds.

SCORECARD

ExistenceGOODA public REST API at api.checkfront.com; v3 documents bookings, items, customers, transactions, and inventory in detail.
AccessPOORNot available on Trial accounts; API access is purchased through sales, and OAuth2 app registration is partner-gated.
CoverageMIXEDCore booking objects are covered, but webhooks stop at five event types; refunds, payments, and inventory changes need polling.
AuthMIXEDOAuth2 or token auth is standard enough; the nonstandard X-On-Behalf header routing adds glue code every app must write.
Docs & DXMIXEDv3 docs are detailed with SDK examples on GitHub, but the throttle thresholds behind the 429s are never published.
StabilityMIXEDv3 sits in maintenance mode while v4 documentation and parity fill in; integrators must guess which generation to target.

Supergood: Checkfront has an API, with gaps. We cover what it's missing: stable endpoints, normalized JSON, managed auth.

SOURCES
API access is gated behind a paid plan and not available to Trial accounts - integrators must engage Checkfront Sales before any development work, slowing partner onboarding. api.checkfront.com
Two parallel API generations (v3 in 'maintenance mode' and v4 as the supposed future) leave partners uncertain which surface to build against; v4 documentation and feature parity is still being filled in. api.checkfront.com
Rate limits return HTTP 429 with Retry-After but the actual throttle thresholds, per-endpoint quotas, and SLAs are not publicly documented - integrators discover limits empirically. api.checkfront.com
Webhook surface is narrow - only Booking, Booking Status Change, Item, Item Event, and Transaction events. Granular customer profile updates, payment-level events, refund events, and inventory/availability change events require polling. api.checkfront.com
OAuth2 app registration is partner-gated rather than self-serve; integrators have to contact Checkfront partnerships to get an Authorize/Access token URL pair provisioned. api.checkfront.com
The non-standard X-On-Behalf header pattern for routing requests between authenticated staff actions and the unauthenticated 'Public API' path adds idiosyncratic glue code that every consuming app must write. api.checkfront.com
Documentation lives across multiple domains (api.checkfront.com for v3, apiv4.checkfront.com for v4, developers.checkfront.com as a landing page, GitHub for SDK examples, the support knowledge base for operator-facing API config) - integrators have to stitch sources together. developers.checkfront.com
API V3 maintenance-mode status means new feature work for the booking platform is not consistently exposed to API consumers - integrators report waiting for v4 endpoint coverage before being able to support newer Checkfront features. support.checkfront.com
Post-Rezdy-merger pricing changes - operators report Checkfront is now pricier than most competitors, with confusing tier restructuring that pushed many users to evaluate alternatives. bokun.io
3% booking fee on lower tiers is double what some competitors (e.g., Bokun at 1-1.5%) charge for comparable functionality. bokun.io
Customer support is not 24/7; phone support is gated to higher-priced plans, and reviewers report slow ticket resolution with workarounds offered instead of fixes. trustpilot.com
Software bugs disrupt booking processes, cause integration errors, and fixes are slow to ship - cited as a recurring operational headache. getapp.com
Front-end booking widget/plugin is unappealing and lacks customization options even after recent UI refreshes; operators dislike the consumer-facing aesthetic. capterra.com
Steep learning curve for administrators - easy for end customers, but complex to configure and maintain on the operator side. softwareadvice.com
Making changes to existing bookings or processing refunds is difficult and time-consuming, leading to staff frustration and operational inefficiency. g2.com
Management shakeup at the Checkfront/Rezdy/Regiondo combined entity since 2024 has created strategy and roadmap uncertainty for operators planning multi-year integrations. arival.travel
