Integration

Add identity verification to your workflow without redesigning everything.

Create the transaction in your system, send the link to the customer and track the final result through webhook, API and certificate.

1

Create a transaction through API, portal or internal workflow

Customers receive a link and complete verification on mobile, without installing an app.

2

Send the link by SMS, WhatsApp, email or your own channel

Liveness, documents and fraud rules are applied when the operation needs stronger trust.

3

The user completes verification on mobile, without installing an app

API, short links, GET reconciliation and signed webhooks reduce manual work.

4

Receive decision, signed webhook and certificate for audit

Status, decision, reason, events and certificates support service, compliance and fraud teams.
