Steps
Request partner API access via Availability Exchange's request-access flow and complete certification against sandbox properties
Authenticate per its API Authentication documentation
Call Get Businesses to enumerate connected properties, then Get Units/Get Unit Groups for inventory
Call Get Availability (or Get All Availability) and Get Rates/Get Lowest Rates for ARI data
Cache and refresh ARI data on a schedule matching your booking channel's freshness requirements
Known gotchas
Full production access requires passing Availability Exchange's certification process after sandbox testing — budget time before a launch date
A property must individually opt in to share availability with your integration; a 'connected' property can still return no data until they enable sharing
