About datasets in Meta Events Manager

We're gradually introducing changes to how your event data is shown in Meta Events Manager. Website, app, offline and messaging events will be merged together into a single view. This is called a dataset. If you have access to the new dataset experience, this page applies to you.

Events are actions that people take within your customer-facing experiences, including your website, mobile app, physical shop location or business chats. You can send data from those sources to us through integrations such as the Meta pixel, Conversions API or Facebook SDK for iOS or Android. Each integration has an ID to help you tell them apart, and we display events in Meta Events Manager under the corresponding integration ID. For example, your pixel ID, app ID or offline ID.

Now, you can connect website, app, offline and messaging event data by creating a dataset. There should be no impact on campaign optimisation and reporting in Ads Manager when you create a dataset.

When you create your dataset, you'll have a dataset ID that you can use to set up your integrations and view your events in Events Manager. You can use your dataset ID like you would use your pixel ID, such as to set up the Meta pixel or Conversions API. If you have an app, your app ID will remain the same and will be linked to your dataset ID.

When a new dataset is created:

• Your dataset ID will be the same as your existing pixel ID if an existing pixel is linked to your dataset. Examples of when an existing pixel is linked to your dataset include when:

  • Your pixel was automatically converted to a dataset.
  • You created a dataset through an existing mobile app and chose the Create from a pixel ID option.
• You'll be given a new dataset ID if an existing pixel is not linked to your dataset. Examples of when an existing pixel is not linked to your dataset include when:

  • Your app was automatically converted to a dataset.
  • You created a dataset through an existing mobile app and chose the Create new option.
  • You created a dataset during offline event set creation.

Datasets may show event data from any of these integrations that you choose to set up:

• Meta pixel (website events)
• Conversions API (website, app, offline and messaging events)
• Facebook SDK for iOS or Android (app events)
• Mobile Measurement Partners (app events)
• App Events API (app events)
• CSV file upload (offline events)

In order to connect app events to your dataset, you first need to link your mobile app ID to your dataset. You'll also have the option to relink your app ID from your dataset.

Datasets enable you to:

• View customer activity based on business need, regardless of the source. Instead of having separate IDs for each of your integrations, you can have a single dataset ID to represent your website, app, offline and messaging event data. This allows you to monitor events and manage your settings in one place.
• Reduce the need to build and maintain multiple API integrations. Historically, the Conversions API was used to directly connect your website data to Meta, and the separate App Events API, Offline Conversions API and Messaging Events API were used to directly connect your mobile app, offline and messaging data. Today, if you create a dataset and link your app, you can use the Conversions API to directly connect your website, mobile app, offline and messaging data. That way, you only need to manage one API integration with Meta.
