Send Optimizely Data Platform data using Advanced Audience Targeting for the GO SDK

Describes the SendOdpEvent method, which sends Optimizely Feature Experimentation event data to the Optimizely Data Platform (ODP) server.



Sending data to Optimizely Data Platform (ODP) through the Advanced Audience Targeting sendOdpEvent method is in beta. Apply on the Optimizely beta signup page or contact your Customer Success Manager.


You must enable the Advanced Audience Targeting integration before sending events to Optimizely Data Platform (ODP) from Feature Experimentation.

Minimum SDK Version



The Optimizely Client extension method, SendOdpEvent, lets you send data to the ODP server. This data can then be used to analyze user behavior and optimize experiences across different channels and touchpoints.

The SendOdpEvent method can be used to

  • Merge or stitch users together and determine which event is associated with which customer.
  • Send various types of events and actions, such as pageviews, clicks, form submissions, and others. When using this method, you can include additional data to provide more context and information about the event being tracked.

For example, by connecting an email address identifier with a fs_user_id identifier, you can use the SendOdpEvent method to send events that are associated with both identifiers. This enables you to track and analyze the behavior of a specific user across different touchpoints and devices.

You cannot create or update user profile data like name or address with SendOdpEvent. Instead, you can use the ODP Create and update customers API endpointor ODP UI to manage customer profiles.

Sending events to Optimizely Data Platform



  • The Go SDK discards the event immediately if there are any errors (sdkNotReady, odpNotIntegrated, or odpNotEnabled).
  • All events (implicit or explicit) will be discarded, if requested before the datafile is ready and a warning log will be sent.
    • It is expected that the datafile is fully ready in the Go SDK before you create user contexts and accept decision requests.


This table lists the required and optional parameters for the SendOdpEvent method.

eventTypeStringThe type of event to be sent. Will be "fullstack" for all Go SDK-generated events if not specified.
StringSpecifies the subcategory of the event type, which is used to track the app and user lifecycle.
identifiersmap[string]stringA key-value map of user identifiers. At least one key-value pair is required.
datamap[string]interface{}The event data in a key-value map. The value can be any type (string, number, or boolean.) Null values are allowed, but are interpreted as empty strings.

The Go SDK adds default event data to the given data dictionary. You can overwrite the default data values by sending the same key when creating your HashMap.

  • "idempotence_id":<UUID created by the Go SDK>

  • "data_source_type":"sdk"

  • "data_source":"go-sdk"

  • "data_source_version":<Go SDK version implemented>


This method sends event data to the Optimizely Data Platform (ODP) server. It returns an error when any issue occurs, otherwise returns nil.


identifiers := map[string]string{"fs_user_id": "user123", "email": "[email protected]"}
data := map[string]interface{}{"item": "shirt", "price": 50.00}

err := optimizelyClient.SendOdpEvent("fullstack", "purchased", identifiers, data)

The network calls between your application, the Go SDK, and the ODP server when calling the SendOdpEvent method is demonstrated below:

  1. Your application calls the SendOdpEvent method.
  2. The Go SDK makes a POST request to ODP.
  3. ODP responds with acknowledgement or relevant error.
