Cookie-based authentication

Configure the React Native SDK to use cookie-based authentication with a custom API base URL.

Recommended: JavaScript SDK for React Native

While this SDK is still supported, we recommend using newer JavaScript SDK, which is optimized for React Native, but also comes with a host of other benefits.

For what cookie-based authentication is, how it works, and full dashboard setup steps, see Cookie-based authentication.

SDK configuration

Once your cookie domain is configured and DNS is validated, pass apiBaseUrl when creating the client to point to your custom hostname:

import { createClient } from '@dynamic-labs/client';

export const dynamicClient = createClient({
  environmentId: 'YOUR_ENVIRONMENT_ID',
  apiBaseUrl: 'https://auth.example.io/api/v0',
  appName: 'My App',
});

Replace auth.example.io with the custom hostname you configured in the dashboard.
