Tagging API

Reference for the Signal V2 tagging endpoints.

What is tagging?

Tagging is the system used to classify and organize posts within a project. Tags can be applied manually or through automated tagging rules.

Each tag belongs to a project and can optionally be placed in a tag folder for grouping. Tags can carry automated tagging rules that assign the tag to posts matching defined text patterns.

What is a tag?

A tag is a label attached to posts inside a project so they can be grouped, filtered, and targeted by rules. Tags can also be assigned to folders for easier organization.

Scope

The tagging area is split into endpoint families:

  • /tag for tag lifecycle and tagging rules
  • /tagfolder for tag folder management
  • related /project endpoints for read-only tag and tag folder listings

Read-only tag and folder listings for a project are exposed through the project area, not through /tag.
