One API for verify,
sign, seal, and evidence.
WeVerify's REST API gives developers programmatic access to every trust product, from identity verification to qualified signing to e-sealing. Hosted no-code flows for speed. Full API access for control. 4-hour enterprise integration (reference implementation), not 4-week projects.
Integration options
Hosted flow for speed. API for control. Both for scale.
Hosted browser flow
Redirect your user to WeVerify's hosted verification URL. No extra SDK needed for hosted flow, REST API and webhooks handle all integration. The user completes verification and is returned to your application with a signed result. Live in hours.
REST API (embedded)
Full programmatic control over every verification step. Embed the verification UI in your own interface using our RESTful API. Customise branding, language, and flow steps.
Webhooks
Receive real-time event notifications on workflow completion, verification result, signature event, and evidence bundle availability. Signed webhook payloads with replay protection.

Platform capabilities
Everything a technical team needs to evaluate and integrate.
Sandbox environment
Full sandbox with test passports, simulated NFC reads, and synthetic biometric results. Test every workflow without real documents. Sandbox evidence bundles are identical in structure to production.
RESTful API & Webhooks
RESTful APIs and webhooks for all integrations. Postman collection and OpenAPI 3.0 specification available for immediate exploration.
Evidence schema
Consistent JSON evidence schema across all products: timestamp, verification result, document data, liveness status, certificate reference, session ID, and cryptographic signature of the bundle itself.
Security
mTLS for API connections. HMAC-signed webhook payloads. IP allowlisting. Encryption in transit (TLS 1.3) and at rest. Key management via HSM. No raw biometric data in transit.
Webhook events
workflow.started Β· verification.completed Β· liveness.result Β· signature.completed Β· seal.applied Β· evidence.ready Β· session.ended Β· error.occurred
Dashboard & analytics
Real-time verification pipeline dashboard. Pass rate by document type, country, and channel. Drop-off analysis. Evidence bundle search and export for compliance review.
