A Click-to-WhatsApp ad opens a chat with your business. The first message arrives with a referral: which ad, its headline and a click id.
What baseNode does with it
The conversation is stamped with the ad that started it, the contact is tagged so you can build a segment of ad leads, and the ad headline shows beside the chat so agents know the context.
When that customer later orders through a connected store, the order is attributed to your campaign activity, so you can see revenue against the messages you sent.
Make it work
Greet ad leads fast: inside the free window a quick reply costs nothing. Use a short chatbot to qualify them, and let lead scoring surface the ones ready to buy.
