# Tracking

For each offer, whenever the user clicks on it, partners must direct users to a Playback tracking link. This allows Playback to track clicks, attribute downstream events, and trigger the correct postbacks.

The offers endpoint will return a tracking link for the offer with the partnerId and offerId parameters prefilled. You just have to add the userId and any optional parameters you may want

## Tracking Parameters

For a complete schema definition of the tracking link, see the [clicks endpoint](/api-reference/tracking/activate-a-partner-offer) reference page.
