Integrate verified human authentication.

Install the SDK.

Add the Entry SDK to your application. Lightweight, no heavy dependencies.

Configure your auth flow.

Define when Entry triggers — login, payment, step-up. Map to your existing user model.

Go live.

Entry handles liveness, biometric matching, key generation, and audit logging. You get a verified or denied response.

import { EntrySDK } from '@synapser/entry-sdk';

// Initialise
const entry = new EntrySDK({
  apiKey: process.env.ENTRY_API_KEY,
  environment: 'production'
});

// Authenticate a user
const result = await entry.authenticate({
  userId: 'user_2xK9mR',
  action: 'payment_authorise',
  metadata: { amount: 15000, currency: 'ZAR' }
});

if (result.verified) {
  // Proceed with transaction
  console.log('Human verified', result.auditId);
} else {
  // Handle rejection
  console.log('Verification failed', result.reason);
}
