Postback URL parameters

A server-to-server (S2S) postback reports a conversion to Skro. The request must include the Skro click ID associated with the original visit. Additional parameters describe the event, revenue, and transaction.

Basic postback URLCopy Anchor Link

https://skrotrack.com/postback?clickId=REQUIRED&payout=OPTIONAL&status=OPTIONAL&transactionId=OPTIONAL

Use the postback URL generated by your affiliate network template in Skro. Replace example values with the provider’s supported macros. If you use a custom tracking domain, use that domain in place of skrotrack.com.

Parameter referenceCopy Anchor Link

clickIdCopy Anchor Link

Skro generates a click ID for a campaign visit. Pass it to the offer using the parameter supported by your network. For example, if the network accepts the value in s2:

https://example.com/offer?s2={clickId}

When a conversion occurs, the network sends the stored value back as clickId. Skro uses it to attribute the conversion to the original campaign and visit attributes, including location, device, and operating system.

Check your network’s guide or ask your account manager which macro returns the stored value.

payoutCopy Anchor Link

Use payout to report revenue per conversion. With Auto payout tracking, populate it with the network’s revenue macro or a fixed value. Manual payout tracking uses the payout configured in Skro.

statusCopy Anchor Link

Use status to report the conversion’s stage, such as a lead awaiting approval or an approved conversion. Your affiliate network must provide a status value or macro.

Configure the status mappings in your Skro affiliate network settings. Templates such as AdCombo include predefined mappings and a postback macro.

transactionIdCopy Anchor Link

Use transactionId to identify individual transactions associated with a click. This is useful when a visitor completes multiple conversion steps, purchases, or upsells.

Pass the network’s transaction macro or a transaction identifier from your own system. Choose a value that identifies the conversion being reported.

payoutCurrencyCodeCopy Anchor Link

Pass the currency of the revenue amount, for example USD, EUR, or GBP. A currency supplied in the postback takes priority over the configured default currency.

protectionTokenCopy Anchor Link

Enable postback protection in the affiliate network settings, then include the configured token in the postback URL.

https://skrotrack.com/postback?clickId=REPLACE&payout=5&protectionToken=YOUR_PROTECTION_TOKEN

Use your own token from Skro; the value above is a placeholder.

ce: custom conversion eventsCopy Anchor Link

Use ce to distinguish events such as installs, registrations, purchases, deposits, and upsells. Configure the accepted values in Custom Conversions before sending them. Your subscription determines the available number of events, up to 20.

For example, an App Install event can accept both inst and install. A postback containing either value is categorized under the configured event:

https://skrotrack.com/postback?clickId=REPLACE&payout=5&ce=install

See Custom conversions for reporting options and traffic source event mappings.

p1–p5: additional dataCopy Anchor Link

Use p1 through p5 to store additional information supplied by the network. Assign each parameter a supported macro or value.

Verify a postbackCopy Anchor Link

1. Open a campaign link and obtain a real Skro click ID from the resulting visit.
2. Confirm that the offer receives that value in the network’s configured parameter.
3. Trigger a test conversion using the network’s test workflow.
4. Check the conversion, event name, revenue, currency, and status in the Skro campaign report.

If a conversion is missing, check the click ID mapping, protection token, and custom event value first. For network-specific macros, follow the matching guide in the integration directory.
