Please help me , WhatsApp Node: Trigger Works but Messages Not Sent After Some Time

flodata · September 3, 2025, 5:23am

I’m facing a problem with the WhatsApp node in n8n.

I have configured a WhatsApp Trigger node with 3–4 numbers.
The trigger fires successfully at the scheduled time.
However, the WhatsApp Message node does not send any message to the users listed.
This happens after some time, even though initially it may work.

Even though the trigger node executes, no messages are sent via the WhatsApp Message node after some time.

Could this be related to token/session expiry in Meta’s WhatsApp Cloud API?
Do I need to handle refresh tokens separately in n8n for WhatsApp?
Is this a known issue/limitation with multiple numbers in the WhatsApp node?

I can share workflow exports or logs if needed.
My main goal is to have the WhatsApp node reliably send messages whenever the trigger fires.

please help me

Hii @flodata Hope You Are Well

I think the trouble you are getting isn’t because of multiple numbers in the WhatsApp node

And if you didn’t exchange your token for a long time one, it will expire

And it is good practice to handle refresh tokens for WhatsApp node

I think you should update your meta developer console & replace temporary tokens to long time tokens

It may fix the trouble you are getting .

we have taken the token for long time but still we are getting same problem.

We have meta developer account paid token. But problem is not solved.

The workflow is not much long but still i am getting the problem.

I have longer token of meta developer account.

I have seen that another guy also is facing the same problem with whatsapp node.
