WhatsApp click-to-chat ad referrals are already stored on incoming
messages, but agents only see the customer’s text. This displays the
originating ad preview directly in the message bubble, including
available media, headline, body, and source link. Attribution
identifiers remain hidden.
### Things to know
- The card renders only when `content_attributes.referral` is present.
- Invalid or non-HTTP media and source URLs fall back safely.
- Existing messages without referral metadata are unchanged.
### How to test
1. Open a WhatsApp conversation containing an incoming message with
`content_attributes.referral`.
2. Confirm the ad preview appears above the customer text.
3. Confirm the source opens in a new tab and missing or invalid media
does not break the message bubble.
