Requests per minute
Reads and writes use separate fixed one-minute windows. Workspace budgets apply to workspace calls and can be exhausted before a key’s own budget. Creating more keys does not increase the shared workspace allowance.
Response headers
A
429 can come from the shared workspace budget even when the key has remaining capacity. Queue work, wait at least Retry-After, and add backoff with jitter. Reconcile uncertain writes before retrying; do not change the logical-operation key.
Size and retrieval limits
Begin reporting syncs at a five-minute interval and adjust to actual need. This is a suggested polling interval, not a new provider quota. For durable operations, a webhook can tell you when the outcome is ready instead of polling.
If request storage is unavailable, the API fails with
503 rather than disabling rate limits or replay protection. Provider and sending guidance covers account activity separately.
