Lemnisk CDP exposes its segmentation/audience of end-users and user macros derived from user behaviour over an endpoint. This is made available as a DataProvider for Adobe Target to consume. Our customers who have Adobe Target can consume this real-time segmented user information for creating audiences and experiences in Target.
Getting Started
Adobe Launch Extension can make the data provider available directly in AEM. You can also add this to AEM directly.
You need a server URL to configure DataProvider. Based on the region, we have three server URL. If you're not sure which one to configure, please contact your Lemnisk Customer Success Manager.
var lemniskDataProvider = {
name: "Lemnisk Dataprovider",
version: "1.1.0",
timeout: 1500,
config: {
advid: '100001',
server: <server url based on your region>,
caching: false,
ttl: 24 * 60 * 60 * 1000 //Number of milliseconds in a day

window.targetGlobalSettings = {

lemniskDataProvider
]
};
The configurations are present in the config key. For advid, server, please reach out to your customer success partner.
Thetimeoutfield is about how long Target will wait for the DataProvider to load.
Theconfig.cachingcan be set to true if the DataProvider data can be cached (for config.ttl period - this is in milliseconds). This will make the DataProvider return data from local storage instead of reaching the servers.
Data Flow
The DataProvider relies on the Lemnisk AdServer endpoint which lists down the active segment for this user and the relevant customization parameters. For example:
The above URL (at the time of this documentation) returns:
This data is passed over to Adobe Target via a mbox call as shown below:
Using the data, we can create audiences and offers in Adobe Target.
The page gets customized for the end-user as shown below:
For users where no segmentation is available, Target will continue to serve the default experience.
You will have to list the DataProvider before Target scripts are added. This needs to be loaded at.js
