Steps
Choose your access path: direct Hostfully accounts use an X-HOSTFULLY-APIKEY header from Agency Settings, while partners building for multiple customers use Basic Auth to exchange an OAuth 2.0 Authorization Code for per-customer tokens.
Develop and test entirely against Hostfully's sandbox first; production access is enabled only after sandbox testing is confirmed working.
Use the Leads endpoints to manage bookings, since Hostfully models a reservation as a "lead" moving through states like inquiry, hold, and booked rather than a flat reservation object.
Pull rates/availability via the Property Calendar endpoints, and register a webhook subscription for lead/reservation changes instead of continuous polling.
Monitor the x-ratelimit-limit and x-ratelimit-remaining response headers, since Hostfully allows up to 10,000 calls per rolling 1-hour window per calling client.
Known gotchas
Hostfully's "Lead" state machine (inquiry, hold, booked, cancelled, rebook, etc.) means a naive integration expecting a flat reservations resource will miss key accept/decline/hold actions core to the API.
Sandbox API keys visible on a partner's own Agency Settings page must not be used to authenticate a partner integration — Hostfully explicitly requires going through the OAuth flow with a separate sandbox test account instead.
Abusing rate limits can get a client application blacklisted outright rather than just throttled, requiring a support request to restore access.
