Traffic Source Postbacks

What Postbacks Are

Postbacks are HTTP callbacks sent to traffic sources when
events occur on their leads. The most common postback is a
conversion notification: when a lead from a traffic source
converts, Trackdrive fires an HTTP request to the source's
postback URL with conversion details.

How Postbacks Work

Postbacks are implemented through the outgoing webhook
system. Each traffic source can have one or more outgoing
webhook URLs configured (ordered by priority). When a
triggering event occurs (conversion, call status change,
etc.), the system enqueues an outgoing webhook request with
the event payload.

Postback URL Tokens

Postback URLs support token substitution. Tokens like
{call_id}, {payout}, {duration}, and custom lead tokens
are replaced with actual values before the request is
fired. This allows traffic sources to receive data in
whatever URL format their tracking system expects.

Retry Behavior

Failed postback deliveries are retried according to the
outgoing webhook retry policy. The system logs each attempt
and its HTTP response status for debugging failed
integrations.
