# Concept: Product

A **product** is one Atlassian Marketplace app that Marketplace Events watches — for example a Jira or Confluence app you publish. It is the unit of syncing and the unit of metering.

Each product is tied to one Atlassian **credential** (the developer-space token used to read its licences and transactions) and has any number of **destinations** (connections) that receive the events synthesised from that data.

A product moves through a small set of statuses: `pending_backfill` (added, awaiting its first history load), `active` (syncing normally), `payment_required` (over the free event limit and paused), `disabled`, and `error`.
