Segment definitions endpoint

Adobe Experience Platform allows you to create segments that define a group of specific attributes or behaviors from a group of profiles. A segment definition is an object that encapsulates a query written in Profile Query Language (PQL). This object is also called a PQL predicate. PQL predicates define the rules for the segment based on conditions related to any record or time-series data you supply to Real-time Customer Profile. See the PQL guide for more information on writing PQL queries.

This guide provides information to help you better understand segment definitions and includes sample API calls for performing basic actions using the API.

Getting started

The endpoints used in this guide are part of the Adobe Experience Platform Segmentation Service API. Before continuing, please review the getting started guide for important information that you need to know in order to successfully make calls to the API, including required headers and how to read example API calls.

Retrieve a list of segment definitions

You can retrieve a list of all segment definitions for your IMS Organization by making a GET request to the /segment/definitions endpoint.

API format

The /segment/definitions endpoint supports several query parameters to help filter your results. While these parameters are optional, their use is strongly recommended to help reduce expensive overhead. Making a call to this endpoint with no parameters will retrieve all segment definitions available for your organization. Multiple parameters can be included, separated by ampersands (&).

GET /segment/definitions
GET /segment/definitions?{QUERY_PARAMETERS}

Query parameters

Parameter Description Example
start Specifies the starting offset for the segment definitions returned. start=4
limit Specifies the number of segment definitions returned per page. limit=20
page Specifies which page the results of segment definitions will start from. page=5
sort Specifies which field to sort the results by. Is written in the following format: [attributeName]:[desc|asc]. sort=updateTime:desc
evaluationInfo.continuous.enabled Specifies if the segment definition is streaming-enabled. evaluationInfo.continuous.enabled=true

Request

The following request will retrieve the last two segment definitions posted within your IMS Organization.

curl -X GET https://platform.adobe.io/data/core/ups/segment/definitions?limit=2 \
 -H 'Authorization: Bearer {ACCESS_TOKEN}' \
 -H 'x-gw-ims-org-id: {IMS_ORG}' \
 -H 'x-api-key: {API_KEY}' \
 -H 'x-sandbox-name: {SANDBOX_NAME}'

Response

A successful response returns HTTP status 200 with a list of segment definitions for the specified IMS organization as JSON.
