Pre-launch callback test
Send a sample conversion URL before launch and confirm that status, payout, and click ID values reach the endpoint without syntax or auth errors.
Send sample conversions through your tracker or affiliate network before traffic goes live.
Postbacks connect the revenue in your affiliate network to the conversions inside a tracker. When they fail, payouts vanish, optimization algorithms stall, and advertisers question the data. Use this tester to fire mock conversions at your callback URL before campaigns go live.
Media buyers can run this test after every funnel rebuild and during onboarding. Instead of sending screenshots of 404 responses, share the raw payload and prove whether partner-side firewalls or tracker redirects are at fault.
Paste a callback URL with macros or sample values and capture the response before campaigns run.

Postback Tester helps you reproduce real callback flows, inspect raw responses, and confirm that tracker or network postbacks behave correctly before live conversions are at stake. It is most useful when you treat the callback as one layer in a broader attribution chain that also includes the resolved landing page, the click identifier stored on that page, and the downstream system that should later credit the conversion.

Replay the exact callback a partner says they sent, capture the response, and escalate with a reproducible log instead of a vague "postback looks fine" claim.
Test tracker macros after a template update and make sure the callback still resolves cleanly before you trust live conversion totals.
Pair the callback log with the Redirect Checker trace and Click ID Extractor output from the same funnel so nobody argues about whether the identifier was lost before or after the conversion event.
A strong postback investigation stays ordered. First confirm the visitor and click identifier reached the correct landing page, then confirm the conversion event exists in the tracker or CRM, and only then replay the outbound callback. This prevents teams from editing templates blindly when the real gap lives upstream or in partner-side validation.
Step 1
Run the campaign URL through Redirect Checker and keep the final landing page, redirect owner, and query-string history in the same incident note as the callback test.
Step 2
Open the final landing URL in Click ID Extractor so you know whether fbclid, gclid, or another click ID survived before the tracker tries to send it back out in the postback.
Step 3
Use sample payout, status, transaction, and goal values that are easy to recognize in logs, then save the raw response, headers, and latency as the canonical proof of what the partner endpoint returned.
Step 4
If the endpoint never receives the request, move to transport and delivery troubleshooting. If the request arrives but fields are wrong, compare the template against the live request. If the endpoint returns 200 but credit still fails, move to the conversion-credit fix path instead of resending the same payload forever.
Most postback incidents stall because each team captures different artifacts. Keep one minimal proof set so network support, tracker admins, and revenue teams can all review the same facts.
The original campaign URL or tracker link that generated the click.
The Redirect Checker trace showing the final landing page and whether query parameters changed mid-route.
A Click ID Extractor snapshot proving which identifier reached the landing page before conversion.
The exact callback URL or payload you replayed, including auth fields, payout, status, and goal naming.
The raw response body, status code, headers, and latency returned by the partner endpoint.
The partner or tracker log entry you expect to match against the replayed test.
A successful HTTP response is useful, but it is not the same thing as a healthy attribution workflow. Use these checks to avoid false confidence.
The callback returns 200 but the partner ignores the event because goal names, currency, deduplication keys, or auth fields are still wrong.
The payload is technically valid, but it no longer matches the identifier format the landing page or CRM actually stored.
A team keeps replaying a clean test callback even though the live issue starts earlier in redirect routing, click-ID capture, or conversion logging.
Finance, CRM, and tracker owners each review different screenshots, so nobody notices that the callback and the conversion record refer to different transactions.
