Send message not working for users number

[Himanshu_wasnik]

I’m working with n8n + WhatsApp Cloud API.

When I send a message from my own WhatsApp number, the reply works perfectly.
But when I try sending a message from a different WhatsApp number, the workflow fails with an error while sending the reply (DNS / server offline type error).

Webhook receives the message correctly, but the send message step fails only for other numbers.

I’m currently using:

• Meta test number

• Phone Number ID as sender

• messages[0].from as recipient

Has anyone faced this issue?
Do I need to add all recipient numbers as test users, or is this related to app mode (dev vs live)?

Any guidance would be appreciated. Thanks!

Hope this helps!
