WhatsApp ad referral tracking and ctwa_clid attribution

Business problem

When a customer initiates a conversation via a Click-to-WhatsApp ad, Meta provides a referral object containing critical tracking data such as the ad ID, source URL, and unique click identifier (ctwa_clid). Trengo currently does not capture or surface this data in the inbox, webhooks, or API, preventing businesses from identifying which specific ads are driving customer inquiries.

Wished result

Capture and expose the WhatsApp referral object data (specifically the ctwa_clid) within the inbound webhook and the messages REST API. Ideally, this information should also be visible as a ticket field in the inbox, allowing users to send conversion data back to Meta’s Conversions API for accurate campaign attribution and ROI tracking.
