```

## Quick start

```typescript theme={"system"}
import { MederaAuth, MederaClient } from '@medera/sdk';

const auth = new MederaAuth({
  clientId: process.env.MEDERA_CLIENT_ID!,
  clientSecret: process.env.MEDERA_CLIENT_SECRET!,
  audience: 'api.medera.info',
});

const client = new MederaClient({ auth });

const session = await client.sessions.create({
  patient_id: 'pat_abc',
  provider_id: 'prv_xyz',
  visit_type: 'psychiatry_followup',
});

```
