Veriff

Veriff is an enterprise identity verification platform with particularly broad document coverage — supporting 10,000+ document types from 190+ countries — making it well-suited for products with global or international user bases where narrow document support creates onboarding friction. The API enables agents to create verification sessions, receive completion webhooks, and retrieve verification decisions with supporting evidence. Veriff's fraud prevention capabilities supplement the basic verification with behavioral signals and fraud pattern detection.

The API covers session creation, decision retrieval, and media (the verification photos and documents). Agents create sessions with the user's expected document type, the user is redirected to the Veriff verification flow, and the agent receives a webhook with the decision outcome. The decision data includes the overall verification result, specific check outcomes, and extracted document information structured for downstream use.

Reliability is enterprise-grade for identity verification infrastructure. Veriff maintains the availability and compliance certifications (ISO 27001, SOC 2) necessary for regulated industry clients. The verification session model is async — sessions have configurable expiry times, and agents should handle both completion and expiry webhook events.

Authentication uses API keys with HMAC signature verification for webhooks. The webhook signature verification is important for compliance use cases — agents should validate webhook signatures to confirm that decision data actually originated from Veriff rather than a spoofed source. API keys are separated by environment (test vs. production).

Documentation is thorough and compliance-context-aware. The decision code reference (documenting the specific reason codes for declined verifications) is particularly useful for agents implementing downstream handling of verification failures. Teams building agent-driven global KYC workflows will find Veriff's documentation covers the international document considerations clearly.
