# Permissions

These permissions are exported as constants of the `react-native-health` module.

```typescript
import AppleHealthKit, { HealthValue, HealthKitPermissions } from 'react-native-health';

/* Permission options */
const permissions = {
  permissions: {
    read: [
      AppleHealthKit.Constants.Permissions.HeartRate,
    ],
    write: [
      AppleHealthKit.Constants.Permissions.Steps,
    ],
  }
} as HealthKitPermissions


AppleHealthKit.initHealthKit(permissions, (error: string) => {
  /* Called after we receive a response from the system */
