WNS: The Notification payload is invalid

Hi Natheem,

Thank you for your reply!

I have configured the Package SID and Security Key for Windows (WNS) in ANH, and no other platforms are currently configured.

Unfortunately, after using the payload you provided and double-checking for any errors, the issue persists.

Could you please guide me on where to check if the registration is set to the "Windows platform" (rather than raw-only), as you mentioned?

Best Regards,

T.

Hello TRX,

let’s fix that payload.

Most likely cause: the toast XML you sent isn’t a valid WNS toast template for the target Windows version/registration (or it has stray characters/BOM). Try the modern ToastGeneric payload (works on Win10+ UWP) — example you can paste in the portal:

<?xml version="1.0" encoding="utf-8"?>
<toast>
  <visual>
    <binding template="ToastGeneric">
      <text>Contoso</text>
      <text>Your test message here</text>
    </binding>
  </visual>
</toast>

If you target older Windows/Windows Phone templates use ToastText01/ToastText02 and include the correct <text id="1"> / <text id="2"> elements. Also check: (1) registration is for Windows platform (not raw-only), (2) your Notification Hub has valid WNS credentials, and (3) the payload has no hidden BOM/extra chars and is well-formed XML.

If you want, paste the exact XML you tried and I’ll point out what’s wrong. Hope this helps — try this once.
