The publisher is able to pass custom key-values to the ad server by using the system. This information needs to be provided in the data layer. It can be done by using ‘atf-targeting’ parameter. There is no limitation of numbers of key-values pairs that can be passed. However, we always suggest removing unused pairs.
Examples:
pushing single key-value pair
dataLayer.push({'atf-targeting': { 'atf_sdk_custom_key': 'testing'}})
pushing 2 or more key values
dataLayer.push({ 'atf-targeting': { 'atf_sdk_custom_key': 'testing', 'atf_sdk_custom_key2': 'test2', 'atf_sdk_custom_key3': 'test3' } })
pushing more than 1 value for a key
dataLayer.push({ 'atf-targeting': { 'atf_sdk_custom_key4': ['test', 'test2']} })
example of entire data layer script for <head> section with key-value parameter
<script type="text/javascript">´ window.dataLayer = window.dataLayer || []; dataLayer.push({ 'atf-contentType': 'gallery' }); dataLayer.push({ 'atf-channel': 'testchannel123' }); dataLayer.push({ 'atf-targeting': {'atf_sdk_custom_key': 'testing'}}) </script>
