Docs & DXGOODA real developer portal documents all three APIs plus webhook registration with retry on failure.
StabilityMIXEDRate limits are enforced but per-endpoint quotas are under-documented; integrators hit them in production.

SOURCES
Developer documentation is fragmented across three separate spec sites (rezdyapi, rezdyconnect, agent) with inconsistent examples and no unified OpenAPI bundle developers.rezdy.com
Rate limits are enforced but the exact per-endpoint quotas and burst behavior are under-documented; integrators discover limits by hitting them in production developers.rezdy.com
No published SDKs in any language, third parties (e.g., dltHub Python source, ColorWhistle case study) maintain unofficial wrappers dlthub.com
Authentication is a single long-lived API key passed as a query parameter (not header), which is a long-standing security anti-pattern for production integrations developers.rezdy.com
No bulk export endpoint, historical booking and customer data extraction requires paginated polling across many endpoints, which makes migration off-platform painful developers.rezdy.com
Webhook event coverage is narrow, booking lifecycle is covered but channel-manager events, payout events, refund events, and customer-data-change events are not exposed developers.rezdy.com
Channel-manager OTA mappings (which products are distributed to Viator vs GetYourGuide vs Klook, with which markup, with which fee split) are not addressable via API, operators must manage this in the Rezdy UI rezdy.com
Agents that integrate via the Agent API report long onboarding cycles to get supplier products 'shared' to them; this is a manual, supplier-controlled toggle rather than a programmatic flow developers.rezdy.com
RezdyPay payment/payout data has limited API exposure relative to direct Stripe/Adyen integrations, operators that need finance-grade payout reconciliation often integrate directly with the underlying gateway rezdy.com
Operators report being forced onto a 'Marketplace' plan that charges 3% of all bookings (including offline/manually-entered bookings) with an ultimatum to switch within 3 days or leave the platform trustpilot.com
Activities and transfers booked at certain times generate customer-facing documents with different times or dates, causing guest distrust and operator embarrassment trustpilot.com
Basic bugs in the booking and document-generation flow remain unfixed for extended periods, impacting both operators and end-guests trustpilot.com
Add-on and per-person tiered pricing structures don't behave as expected; operators discover gaps only after going live capterra.com
Support is widely described as slow, email-only, and unhelpful, particularly post-Checkfront acquisition trustpilot.com
Booking-fee structure stacks on top of subscription fees across all plans (1.9%-3% per booking on top of $49-$249/month) and operators feel the effective take rate is opaque bokun.io
Multiple users report Rezdy 'no longer cares about smaller operators' since the 2023 Checkfront acquisition and the subsequent Booking Holdings ownership trustpilot.com
Channel-manager mappings to Viator/GetYourGuide require ongoing manual maintenance; mismatches between Rezdy product structure and OTA product structure surface as guest-facing errors capterra.com
Reporting and analytics module is shallow, operators end up exporting CSVs to spreadsheets or BI tools to get usable views g2.com
Mobile app functionality lags the web product (limited manifest editing, walk-up booking gaps) capterra.com
