The short answer
Error 130403 means the business account itself blocked this customer's number, so Meta sends them nothing. Do not resend; if you want to message them, unblock the number first, then send.
Why error 130403 appears
- A team member blocked the number from the inbox or from the WhatsApp Business app.
- The number is on an old block list on the account.
How to fix it, step by step
- Check the block was intended
If the customer was abusive, leave the block in place and do not message them.
- Unblock if it was a mistake
From the account's blocked list, then send again.
What ArabyBot does about it
- The reason appears in plain words under the message itself in the inbox, on the web and in the phone app, with what to do — instead of Meta's raw English.
