# Syndication

> Toggle syndication of audiences, event sources, and catalogs to ADCP agents

Syndication pushes a buyer resource — an audience, event source, or catalog — to one or more ADCP agents so they can act on it. You toggle syndication ON or OFF per resource per agent, and each toggle creates a status record that progresses from `PENDING` through `SYNCING` to `COMPLETED` (or `FAILED`).

Toggling returns the status record immediately; because the sync itself is asynchronous, query the status endpoint to confirm a record has reached `COMPLETED`.

All requests use the base URL `https://api.interchange.io/api/v2/buyer` and a `Authorization: Bearer $SCOPE3_API_KEY` header.
