Click-to-WhatsApp attribution needs three things: capture the ctwa_clid click ID from the first message, keep it with the conversation, and send the lead or sale back to Meta's Conversions API. Shared inbox and chatbot tools such as Wati, Chatfuel and Deskwoot do this inside their own inbox. Developer APIs such as Zernio expose it for you to build on. HeyMotek focuses on sending WhatsApp contacts to several ad platforms. FlowTracker attributes WhatsApp and Telegram funnels together, including ads that go to a landing page before WhatsApp. Pick by where your team already works.
Decide whether you need a new inbox or want to keep the one you have.
Check which routes you run: click-to-WhatsApp only, or also ad to landing page to WhatsApp.
Check which ad platforms must receive the conversion.
Check whether sales close in the chat, on a payment link, or in a CRM, and whether the tool can see that moment.
Test with Meta's Test Events before switching budgets.

Tools that capture ctwa_clid and call the Conversions API. Each tool's own documentation states whether it does; links are in the table above.
Yes, but not with ctwa_clid. The click has to be captured on the page and carried into the chat.
FlowTracker covers click to WhatsApp ads and landing page routes, matches purchases closed inside the conversation, and returns the conversion to Meta, TikTok and Google.
