JSON Tag and JSON Client were created to enable a vendor-agnostic data collection using server-side Google Tag Manager (ssGTM). This approach provides a highly flexible and controlled way to send data to various destinations.

• JSON Tag is a tag template for client-side Google Tag Manager (GTM), allowing you to define custom JSON payloads and to send them to your ssgtm instance.
• JSON Client is a client template for ssGTM that receives JSON Tag events, transforms the payload into event data and enables forwarding to any destination using ssGTM tags.

To support session and user (re)identification, an ID Service has been integrated. This service uses server-set cookies, ensuring the most reliable possible visitor tracking when no login ID is available.

In this session we will go through the setup of JSON Tag and JSON Client and will showcase some interesting use cases of it.
