Sumsub Rate Limits

Machine-readable rate limit definitions for the Sumsub API. Sumsub does not publish a fixed public per-key rate limit on the API reference; values below are scaffold defaults reflecting typical Cockpit-tier behavior and should be reconciled with contractual or account-specific limits.

Sumsub Rate Limits is the machine-readable rate-limit profile for Sumsub on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions, across the trial, basic, compliance, and enterprise tiers, measuring verifications_per_trial and requests_per_minute.

Limit state is signalled in the retryAfter response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include AML, Identity Verification, KYC, Quotas, and Rate Limiting.

Policies

App Token Authentication
All requests must include an X-App-Token header. Limits are enforced per token; rotate tokens via the Cockpit dashboard.
Backoff Strategy
Clients should implement exponential backoff with jitter when 429 or 503 responses are received, honoring the Retry-After header when present.
Webhook Delivery
Sumsub retries failed webhook deliveries with backoff; consumers should respond with a 2xx within the documented timeout window to avoid suspension of delivery.
Fair Use
Even on uncapped enterprise contracts, sustained traffic that materially impacts shared verification infrastructure may be throttled per fair-use terms.
Sandbox Isolation
Sandbox traffic is metered separately from production and may have stricter limits to prevent abuse of free trial volume.
