Hello @hartamas,

As per Meta’s documentation, the error (#131026) Message Undeliverable can occur if:

The recipient number is not a valid WhatsApp number.
The recipient has not accepted the latest WhatsApp Terms of Service & Privacy Policy.
The recipient is using an outdated WhatsApp version (minimum supported versions: Android 2.21.15.15, iOS 2.21.170.4, KaiOS 2.2130.10, etc.).

To resolve this, kindly request the recipient to:

Confirm they can send a WhatsApp message to your business number.
Update their WhatsApp application to the latest version.
Accept the latest Terms of Service in Settings > Help or Settings > Application information.

Once these steps are completed, please try sending the message again.
