I’m having trouble with an automated workflow. When someone joins my AWeber mailing list, I want them automatically enrolled in my membership site using DAP (Digital Access Pass).
I followed the DAP developer documentation and configured a webhook in Zapier’s POST action. However, the integration isn’t functioning properly. The webhook appears to send but nothing happens on the receiving end.
The strange part is that Zapier’s activity logs indicate the webhook fired successfully with a positive response. But DAP shows no incoming data whatsoever.
DAP’s support team confirmed their script never gets executed because their server logs remain empty. When they manually paste the webhook URL into a browser and hit enter, the data shows up in their logs immediately.
Zapier support mentioned they don’t provide debugging assistance and suggested posting in community forums.
Has anyone encountered similar webhook delivery issues where the sending platform reports success but the receiving system gets nothing? Any troubleshooting suggestions would be greatly appreciated.
Sounds like a webhook URL mismatch between your test and production setups. When DAP support tested manually in their browser, they sent a GET request. Zapier sends POST requests by default. Your webhook endpoint might handle these differently or use separate URLs for each method. Zapier could also be hitting a cached or redirected version of your URL. I’ve seen servers return a 200 status for the redirect itself, so Zapier thinks it worked while your actual endpoint never gets called. Double-check the exact URL you gave Zapier matches what DAP expects for POST webhooks. Watch out for trailing slashes or query parameters - they matter. Also check if DAP needs specific user-agent strings or has IP whitelisting that blocks Zapier’s servers but allows browser tests.
i totally get what ur going through. it might be a missed setting or smth. check those headers and auth tokens in zapier, that has tripped me up b4. it’s super annoying when it seems all good but nada happens. keep at it!
Classic webhook payload formatting issue. Had the exact same problem with ActiveCampaign and a PHP script last year. The sender claimed success, but my script couldn’t see the data.
Turned out to be content-type headers. Zapier was sending application/json while my script expected application/x-www-form-urlencoded. Got a 200 response but the data processing failed silently.
Since DAP’s manual test works, compare what your browser sends vs what Zapier sends. Use RequestBin or ngrok to intercept both requests - check the headers, payload format, and HTTP method. You’ll spot the difference right away.
Also check if DAP expects specific parameter names or data structure that’s different from Zapier’s POST format.
Been there! Had the exact same headache connecting our CRM to a third-party API last month.
Zapier’s getting a 200 response, but that doesn’t mean DAP actually processed anything. They’re just not talking the same language.
Honestly? Ditch the integration headaches and try Latenode instead. You get way more control over webhook formatting and can actually debug what’s being sent.
Set up your AWeber trigger, then customize the payload format to match exactly what DAP wants. Real monitoring shows you if the data actually makes it to DAP’s system.
It handles these picky integrations way better than Zapier - you can tweak every detail of the HTTP request. No more guessing about headers or payload structure.
