Server-Side Tagging (SST) Glossary
API Endpoint
A URL where the server-side GTM container receives incoming HTTP requests containing event data.

Client
A component in server-side GTM that processes incoming HTTP requests and converts them into a standard event data format.
Learn more: GTM Clients
Client Template
Customizable code that defines how raw HTTP requests are processed and transformed into the Common Event Format.
Learn more: Custom Templates
Common Event Format
Standardized data structure used within server-side GTM to represent events consistently across different sources.
Learn more: Common Event Format
Container Config
Settings that control the server-side container's behavior, including permissions, network access, and security rules.
Learn more: Container Configuration
Custom Domain
A branded domain name that replaces the default GTM domain for receiving server-side events.
Learn more: Custom Domains
Data Layer
Server-side equivalent of the client-side data layer, containing event data in the Common Event Format.
