Advanced Audience Targeting segment qualification methods for the JavaScript (Browser) SDK
Use the Optimizely Data Platform (ODP) Advanced Audience Targeting segment methods to fetch external audience mapping for the user. You can fetch user segments with the user identifier of the user context.
Note
Advanced Audience Targeting and the segment qualification methods are currently beta. Contact your Customer Success Manager for more information or register now on Optimizely.com.
fetchQualifiedSegments
Minimum SDK Version
5.0.0-beta
Description
Fetches all qualified segments for the user context.
fetchQualifiedSegments
is a method of the UserContext
object. See OptimizelyUserContext for details.
Parameters
The following table describes the parameters for the fetchQualifiedSegments
method:
Parameter | Type | Description |
---|---|---|
options (optional) | OptimizelySegmentOption[] | A set of options for fetching qualified segments from ODP. |
Returns
This method returns a Promise<bool>
, which will resolve with true
if segments are fetched successfully, and false
otherwise.
Qualified segments array
You can read and write directly to the qualified segments array. This allows for bypassing the remote fetching process from ODP or for utilizing your own fetching service. This can be helpful when testing or debugging.
Example fetchQualifiedSegments
The following is an example of calling the fetchQualifiedSegments method and accessing the returned completion object:
const attributes = { "app_version": "1.3.2" };
const user = optimizely.createUserContext("user123", attributes);
const asyncFunction = async () => {
const fetched = await user.fetchQualifiedSegments()
console.log(fetched) // true
console.log(user.qualifiedSegments) // Updated qualified segments for target user
}
Once the segments have been fetched, they are cached. This means that if the same user is requesting the segments again (when new user contexts are created), the audience segment information can be retrieved from the cache instead of being fetched again from the remote ODP server.
If you would like to bypass caching, you can add the following options to your options
array:
OptimizelySegmentOption.IGNORE_CACHE
– bypass segments cache for lookup and saveOptimizelySegmentOption.RESET_CACHE
– reset all segments cache
fetchQualifiedSegments network diagram
The network calls between your application, the JavaScript (Browser) SDK, and the ODP server when calling fetchQualifiedSegments
is demonstrated below:

- Call
fetchQualifiedSegments
method. - JavaScript (Browser) SDK makes GraphQL call to ODP to fetch segments.
- ODP responds with segments.
- Fetched segments mapping user IDs to segments are cached.
- Appropriate variations are returned for user.
isQualifiedFor
Version
5.0.0-beta
Description
Check if the user is qualified for the given segment.
Parameters
The following table describes the parameters for the isQualified method:

segment | String | The ODP audience segment name to check if the user is qualified for |
Returns
true
if the user is qualified.
Examples
The following is an example of whether or not the user is qualified for an ODP segment
const attributes = { "laptop_os": "mac" };
const user = optimizely.createUserContext("user123", attributes);
const isQualified = user.isQualifiedFor('segment1');
console.log(isQualified); // true
