Record events

Record Event

The Amplify Analytics plugin provides a simple interface to record custom events within your app:

1let properties: AnalyticsProperties = [
2    "eventPropertyStringKey": "eventPropertyStringValue",
3    "eventPropertyIntKey": 123,
4    "eventPropertyDoubleKey": 12.34,
5    "eventPropertyBoolKey": true
6]
7
8let event = BasicAnalyticsEvent(
9    name: "eventName",
10    properties: properties
11)
12
13Amplify.Analytics.record(event: event)

Flush Events

By default, events are automatically flushed out to the network every 60 seconds.

If you would like to change this, update amplifyconfiguration.json and set the value you would prefer under autoFlushEventsInterval, expressed in seconds:

1{
2  "UserAgent": "aws-amplify-cli/2.0",
3  "Version": "1.0",
4  "analytics": {
5    "plugins": {
6      "awsPinpointAnalyticsPlugin": {
7        "pinpointAnalytics": {
8          "appId": "AppID",
9          "region": "Region"
10        },
11        "autoFlushEventsInterval": 60
12      }
13    }
14  }
15}

Note

Setting autoFlushEventsInterval to 0 will disable the automatic flush of events and you will be responsible for submitting them.

To manually submit the recoded events to the backend, call:

1Amplify.Analytics.flushEvents()

The plugin automatically batches requests in order to reduce network bandwidth and handles the retry logic if the device loses connectivity.

Authentication events

Indicate how frequently users authenticate with your application.

On the Analytics page, the Users tab displays charts for Sign-ins, Sign-ups, and Authentication failures.

To learn how frequently users authenticate with your app, update your application code so that Pinpoint receives the following standard event types for authentication:

• _userauth.sign_in
• _userauth.sign_up
• _userauth.auth_fail

You can report authentication events by doing either of the following:

• Managing user sign-up and sign-in with Amazon Cognito user pools.

Cognito user pools are user directories that make it easier to add sign-up and sign-in to your app. As users authenticate with your app, Cognito reports authentication events to Pinpoint. For more information, see Using Amazon Pinpoint Analytics with Amazon Cognito User Pools in the Amazon Cognito Developer Guide. Also update amplifyconfiguration.json by adding the PinpointAppId key under CognitoUserPool.

1"CognitoUserPool": {
2    "Default": {
3        "PoolId": "<poolid>",
4        "AppClientId": "<appclientid>",
5        "Region": "<region>",
6        "PinpointAppId": "<pinpointappid>"
7   }
8}

• Manually recording events using the recordEvent() API.

  If you don't want to use Cognito user pools, you can use the Pinpoint client to record and submit authentication events, as shown in the following examples. In these examples, the event type is set to _userauth.sign_in, but you can substitute any authentication event type.

1func sendUserSignInEvent() {
2    let event = BasicAnalyticsEvent(
3        name: "_userauth.sign_in"
4    )
5    Amplify.Analytics.record(event: event)
6}

Global Properties

You can register properties which will be included across all Amplify.Analytics.record(event:) calls.

1let globalProperties: AnalyticsProperties = [
2    "globalPropertyKey": "value"
3]
4Amplify.Analytics.registerGlobalProperties(globalProperties)

To unregister global properties, call Amplify.Analytics.unregisterGlobalProperties():

1// When called with no arguments, it unregisters all global properties
2Amplify.Analytics.unregisterGlobalProperties()
3
4// Or you can specify which properties to unregister
5let globalProperties = ["globalPropertyKey1", "globalPropertyKey2"]
6Amplify.Analytics.unregisterGlobalProperties(globalProperties)
