Firestore Request Delay tag for Google Tag Manager server container

Firestore Request Delay tag allows you to delay the processing of events in Google Tag Manager (sGTM) by fetching, replaying, or storing events within Firebase Firestore. This tag can be used to control when events are triggered by introducing a delay or fetching them at a later time.

What are the benefits:

• Flexible event timing: this tag allows you to introduce controlled delays in event processing, which can be critical for synchronization with backend systems.
• Improved error handling: if an event fails to process, it can be replayed later without losing data.
• Optimized data collection: instead of sending individual events in real-time, this tag lets you collect and batch-process them, optimizing performance and reducing the load on servers.
• Reprocessing capabilities: provides the ability to store and later replay data, which is useful for audit trails, debugging, or resending failed events.

The initial development of this template was done by Lars Friis, and it is now maintained by Stape.
