Tracking notifications

Tracking notifications provide insight into recipient engagement and deliverability. Events are returned via the trackingUrl callback.

• Open notifications: Triggered when an email is opened.
• Click notifications: Triggered when a recipient clicks a link.
• Unsubscribe notifications: Triggered when a user opts out.
• Complaint notifications: Triggered when an email is marked as spam.
• Late bounce notifications: Triggered when an initially accepted email later fails.

If you pass a trackingUrl, Infobip will send these notifications back to your system. The notification payload includes structured data about the event, so you can process it automatically and feed it into your reporting, analytics, or suppression workflows.

For sample notification payloads of events such as opens, clicks, unsubscribes, complaints, and late bounces, see the Receive user events (opens in a new tab) API endpoint.
