```javascript translate=no
  // Passes errors through the reporter.
  reportError(identifier: string, message?: string, _reason?: Error | Object)

  // Passes errors without an ID.
  reportErrorWithoutIdentifier(message: string | undefined, error: Error)

  // Assigns a profile ID.
  setUserProfileID(userProfileID?: string)

  //  Enables or disables sending data to AppMetrica.
  setDataSendingEnabled(enabled: boolean)

  // Sends user profiles.
  reportUserProfile(userProfile: UserProfile)

  // Sends AdRevenue.
  reportAdRevenue(adRevenue: AdRevenue)

  // Sends E-commerce events.
  reportECommerce(event: ECommerceEvent)

  // Sends in-app purchases.
  reportRevenue(revenue: Revenue)
```

### DeferredDeeplinkListener

Listener for receiving deferred deeplinks. Pass its implementation to the `requestDeferredDeeplink(listener: DeferredDeeplinkListener)` method.

```javascript translate=no
// Receives the deferred deeplink
onSuccess(deeplink: string)

// Handles errors when receiving deferred deeplinks
onFailure(error: DeferredDeeplinkError, referrer?: string)
```


### DeferredDeeplinkParametersListener

Listener for receiving deferred deeplink parameters. Pass its implementation to the `requestDeferredDeeplinkParameters(listener: DeferredDeeplinkParametersListener)` method.

```javascript translate=no
// Receives deferred deeplink parameters
onSuccess(parameters: Record<string, string>)

// Handles errors when receiving deferred deeplink parameters
