Invalid input data
Meta rejected the ad welcome message because some of its details are not in the required format.
- Code
meta-4027001- Meta code
- 4027001
What to do now
- Under How customers start the chat, keep either the prefilled message or the quick replies, then save again.
- Open Channels, choose the WhatsApp account, and check every field of the ad welcome message. Correct the flagged field, then save again.
Why this happens
- The ad welcome message has both a prefilled customer message and quick replies. Meta allows only one of them.
- One or more fields of the ad welcome message are in the wrong format.

Repeating the unchanged operation will not resolve this condition. Complete the steps above first. Resend in Inbox creates a new message; use it only when another send is appropriate.
