JavaScript SDK Quickstart

The Heuristik JavaScript SDK gives you full control over the verification flow with a typed API.

Integration flow​

Installation​

npm install @heuristik/sdk

Basic usage​

verification.ts
import { HeuristikClient, Locale } from '@heuristik/sdk';

const client = new HeuristikClient({
  apiKey: 'sk_sandbox_your_key_here',
});

const session = await client.createSession({
  referenceId: 'user-12345',
  locale: Locale.ES,
  metadata: {
    source: 'web',
    campaign: 'onboarding',
  },
});

console.log('Initialize with token:', session.token);
TypeScript support

The SDK is written in TypeScript and provides full type definitions out of the box. No need to install @types packages.
