Send Optimizely Data Platform data using Advanced Audience Targeting

This topic describes the sendOdpEvent method, which sends Optimizely Feature Experimentation event data to the Optimizely Data Platform (ODP) server.



Advanced Audience Targeting and sending ODP data through sendOdpEvent are currently beta. Contact your Customer Success Manager for more information or register now on


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

JavaScript (Node) SDK Version



The Optimizely Client extension method sendOdpEvent lets you send data to the ODP server. You can then use this data to analyze user behavior and optimize experiences across different channels and touchpoints.

Use the sendOdpEvent method 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. 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 API or ODP UI to manage customer profiles.

Sending events to Optimizely Data Platform

The JavaScript (Node) SDK discards the event immediately if there are any errors(sdkNotReady, odpNotIntegrated, or odpNotEnabled).


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

StringSpecifies the subcategory of the event type, which will be used to track the app and user lifecycle.
typeStringThe type of event to be sent. Will be "fullstack" for all JavaScript (Node) SDK-generated events if not specified.
identifiersMap<string, string>A key-value map of user identifiers. At least one key-value pair is required.
dataMap<string, unknown>The event data in a key-value map. The value can be any type (string, number, or boolean.) Null values are allowed but will be interpreted as empty strings.

The JavaScript (Node) SDK will add default event data to the given data dictionary. The default data values can be overwritten by sending the same key when creating your dictionary.

  • "idempotence_id":<UUID created by the JavaScript (Node) SDK>

  • "data_source_type":"sdk"

  • "data_source":"javascript-node-sdk"

  • "data_source_version":<JavaScript (Node) SDK version implemented>


This method sends event data to Optimizely Data Platform (ODP). It does not provide return values.


Method signature for sendOdpEvent:

sendOdpEvent(action: string, type?: string, identifiers?: Map<string, string>, data?: Map<string, unknown>): void;

const identifiers = new Map([["fs_user_id", "user123"], ["email", "[email protected]"]]);

try {
  optimizelyInstance.sendOdpEvent("purchased","fullstack", identifiers, data);
} catch (error) {
  // handle error here
