Limits

Partner-scoped API limit partner
varies
partner-specific; configured in developer portal
Limits are configured per signed partner and visible in the developer portal; consumers should consult their connectivity contact for the agreed ceiling.
Shopping / availability surge partner/endpoint
varies
subject to look-to-book ratio enforcement
Distribution partners are expected to maintain a healthy look-to-book ratio; sustained shopping traffic without bookings may trigger commercial review and rate reduction.

Policies

Backoff Strategy
Clients receiving 429 should implement exponential backoff with jitter and honor Retry-After when present.
Look-to-Book Discipline
Distribution partners are contractually expected to keep look-to-book ratios within agreed bounds; abusive shopping traffic without conversion can lead to rate reduction or contract review.
Idempotency
Use unique idempotency / external transaction IDs on booking and modify operations to safely retry across timeouts without creating duplicate reservations.
Partner-Specific Allowances
Loyalty, corporate, and group partners may receive different limits than leisure / OTA partners; consult the contract for the applicable ceiling.
