Facebook App Events collects required information from one of Segment’s mobile SDKs (iOS or Android) and sends it from Segment’s servers to Facebook App Events servers. This server-to-server connection will not work with our server-side libraries. The Facebook App Events Destination is open-source. You can browse the code on GitHub for iOS.

Use Cases

• Improve mobile app retention with Facebook Ads

Getting Started

The first step is to make sure Facebook App Events supports the source type and connection mode you’ve chosen to implement. You can learn more about what dictates the connection modes we support here.

1. From your Segment UI’s Destinations page click on “Add Destination”.
2. Search for “Facebook App Events” within the Destinations Catalog and confirm the Source you’d like to connect to.
3. Drop in your Facebook App ID which can be retrieved from your Facebook Apps dashboard.
4. Once you turn on the Facebook App Events integration in your app’s Segment project, we’ll start sending track data to Facebook’s App Events endpoints.

Screen

If you haven’t had a chance to review our spec, please take a look to understand what the Screen method does. An example call would look like:

[[SEGAnalytics sharedAnalytics] screen:@"Photo Feed"
                            properties:@{ @"Feed Type": @"public" }];

Our integration also supports using Segment screen events as track events. For example, if you had a screen event named Confirmation you could map the invocation of this to a Facebook app event as you would with Segment track events.

To use this functionality you must opt into it via the integration setting named Use Screen Events as Track Events. Once enabled, you should start seeing screen events populate in Facebook App Events. The screen name you provide will be bookended with the words Viewed and Screen. So, if you have a screen event with the name property set to Welcome, it will show up in Facebook as an event called Viewed Welcome Screen.

Please note, the integration will not automatically translate screen events to spec’d Facebook events as our track method does. If you would like to map these events to specific Facebook events you can do this via the Map your events to Standard FB App Events setting. Please be sure to specify the event as Viewed name Screen where name is the name property of the screen event.

Track

If you haven’t had a chance to review our spec, please take a look to understand what the Track method does. An example call would look like:

[[SEGAnalytics sharedAnalytics] track:@"Article Completed"
                           properties:@{ @"title": @"How to Create a Tracking Plan", @"course": @"Intro to Analytics" }];

When you call track we’ll automatically send that event and it’s properties to Facebook. In the Facebook analytics interface you’ll be able to use the event properties to segment your data.

Facebook App Events doesn’t like events with periods in the name so if you send us an event with periods in the name, we’ll convert all periods to underscores. So if your event is friend.added, we’ll send that to Facebook as friend_added. We also truncate events that are longer than 40 characters long due to Facebook’s API constraints.

Facebook Parameters

We automatically translate our spec’d properties revenue and currency to the appropriate Facebook parameters (valueToSum and FBSDKAppEventParameterNameCurrency), and also send events with revenue to Facebook’s purchase logging method (logPurchase).

If you don’t provide a currency explicitly, we send USD. If any properties don’t match the below, we’ll pass them on as they were sent to us.

Facebook Events

We’ll automatically translate any of your events that match one of our spec’d events that map to Facebook’s spec’d events. The below table shows the out of the box mappings in our integration:

If you send a track event that doesn’t match one of the above events, we’ll send it along to Facebook with the name you provide Segment.

Facebook Recommended Events

The most important events that can help advertisers improve campaign ROI are the conversion events or events closest to the conversion. Those events are marked with an “*” within Segment’s Facebook App Events settings page.

In addition, there are special requirements for dynamic ads. These events are marked with “m” for dynamic ads for mobile, and “t” for dynamic ads for travel within Segment’s Facebook App Events settings page.

Other Features

Facebook Login and Facebook Dialogs

The integration does not automatically support Facebook Login and Facebook Dialogs out of the box (you’d need to write code here regardless!). To use these features you’ll need to set up Facebook’s app delegate hooks by accessing the Facebook SDK directly.

Packaged Integration

In addition to the integration available for both iOS and Android, there is a client-side packaged integration available on iOS. We recommend integrating with the Segment server-to-server integration, but you can use the packaged integration on iOS if you want.

Pre-defined Events and Parameters

The integration currently only supports the FBSDKAppEventNameActivatedApp pre-defined event (via the activateApp handler). All other events are forwarded as custom events. If other pre-defined events are important to you, please contact us.

Troubleshooting

Not seeing events?

You will have to be sure that the IDFA is working within your app, which involves adding the iAD framework.

Simiarly, on Android, you’ll need to include the Play Services Ads library as mentioned here in order for the advertisingId to populate.

Once you have added these, you will start to see the context.device.advertisingId populate and the context.device.adTrackingEnabled flag set to true unless the user has ad tracking limited or is using a mobile ad blocker.

Note: While the network is deprecated, the relevant iOS framework is not.

Missing custom events

Facebook will only accept custom events with alphanumeric names (you can include spaces, “-“ and “_“) that are between 2 and 40 characters in length. Otherwise, Facebook will reject the event payload with a 400 status.
