When WhatsApp messages do not arrive

Step by step

Do it step by step

1. 1
   Step 1:

   Settings shows “Messages are only written to a log — nothing reaches customers”: Mode is still Simulated, or the auth key or the number is missing. Choose “MSG91 — live” and fill both.
2. 2
   Step 2:

   “MSG91 did not accept the auth key”: copy the key again from your MSG91 account, paste it, Save and test again.
3. 3
   Step 3:

   “WhatsApp template not mapped for ORDER_SHIPPED — add it under Settings → Connections → WhatsApp & SMS”: that message has no template yet. Pick one in Settings → Connections → Message templates.
4. 4
   Step 4:

   A template shows “rejected by Meta” with a reason: make it again in MSG91 with the fix, wait for approval, then pick the new one.
5. 5
   Step 5:

   “SMS needs a DLT sender ID — add it under Settings → Connections → WhatsApp & SMS”, or SMS never arrives: fill the sender ID and register the text exactly as VASAH shows it. A new trade name or code validity changes that text — register it again.
6. 6
   Step 6:

   Settings shows “… message(s) could not be delivered”: open “Recent messages” — the red line under Result is the reason. A message is tried 5 times, then marked failed.
