Rotate a subscription's signing secret with a dual-secret overlap window

Mints a new signing secret and returns it ONCE, in this response — like signingSecret at creation, it is never re-returned.Show moreMints a new signing secret and returns it ONCE, in this response — like signingSecret at creation, it is never re-returned. During the overlap window every delivery is signed with BOTH secrets (one v1= value per secret in Mondee-Signature), so a receiver can switch without dropping a delivery; at previousSecretExpiresAt the old secret stops signing. overlapSeconds absent = the platform default. Rotating again while a window is open ends the older window immediately: at most two secrets sign at once. Idempotency-Key is REQUIRED (a replay returns the original response, the same new secret, rather than minting a third). Unknown or cross-tenant webhookId is 404 (existence hidden).

    RATE_LIMITED — the API key or its tenant is over a rate limit; wait for Retry-After, then retry.Show moreRATE_LIMITED — the API key or its tenant is over a rate limit; wait for Retry-After, then retry. Every routed request is counted against two token buckets, the key's and the tenant's (all its keys together): 50 requests a second with a burst of 100 on the standard plan. Every travel verb except polling a search also spends from a supplier budget, per key and per tenant: 10 requests a second with a burst of 20, and a plan may add a daily quota of supplier calls. Answers carry the IETF RateLimit header fields for the tightest bucket consulted (RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, RateLimit-Policy); a refusal adds Retry-After and details.scope (KEY or TENANT), details.budget (PLATFORM or SUPPLIER), details.reason (RATE or DAILY_QUOTA), details.tier and details.retryAfterMs. A sandbox may run with the limiter off, in which case none of these headers is sent. A search that is still warming is a different answer with a different meaning (keep polling). with the key-velocity check on, also details.reason VELOCITY_LIMIT, a soft breach of the API key's own scope (components/responses/VelocityLimited), nextAction slow_down.
