# Click to WhatsApp ads attribution.

Click to WhatsApp ads attribution means knowing which Meta ad drove each conversation and each sale, not just each click. Elocuenti builds it with the Meta conversions API: every pipeline stage sends an event so Meta optimizes for real sales.

## What Elocuenti's ads attribution measures

- **Meta conversions API** It sets itself up when you connect WhatsApp: every pipeline stage sends its event to Meta, with no one installing it by hand.
- **14 events per stage** Lead, qualified lead, cart, order, purchase and more, with a 7-day window from the click on the ad.
- **Click to WhatsApp analytics** Which ads drive the most conversations, the click-to-sale funnel and each campaign's estimated ROAS.
- **Links tracked by channel** Every WhatsApp button carries its own UTM, so you know which ad or post each conversation came from.
- **Meta Lead Ads into your CRM** Every form from your ads becomes a contact with its tag and a welcome WhatsApp template.
- **Every ad to its own pipeline** You send an ad's traffic straight into its own sales pipeline, without mixing it into the rest of your base.

## How ad-to-WhatsApp attribution gets built

- **You connect your Meta Ads account.** With read access to your campaigns, ad sets and ads.
- **The click reaches WhatsApp with its UTM.** The ad's link is tagged by channel and campaign from the very first message.
- **Every stage sends its event.** Lead, qualified lead, purchase and the rest fire toward Meta through the conversions API.
- **Meta optimizes for real sales.** With those events, Meta adjusts who sees the ad to bring in more results like those.

## WhatsApp advertising without attribution vs with the conversions API

Without attribution, an ad is measured by clicks. With the conversions API, it's measured by what it actually sold.

| Aspect | No attribution | With Elocuenti's attribution |
| --- | --- | --- |
| What gets measured | Clicks on the WhatsApp button | Lead, sale and every pipeline stage |
| Meta's optimization | By clicks or messages started | By real sale events, via the conversions API |
| Conversation source | Lost once it reaches the chat | Tagged by ad and campaign |
| Meta forms | Sit inside the ads manager | Become a contact with a welcome template |
| ROAS | Estimated outside the platform | Estimated with the pipeline's real sales |

## WhatsApp ads at every point of the pipeline

- **Click to WhatsApp** The ad opens the conversation directly, with its UTM and its event ready from the first message.
- **Meta Lead Ads** The ad's form comes in as a contact, with a tag and a WhatsApp follow-up template.
- **Rules per ad** You route a specific ad's traffic to a different pipeline, without touching the rest of the setup.

## Why the conversions API improves your ads

Meta optimizes better when it knows which click ended in a sale, not just a click. The conversions API sends that data back, event by event, from the conversation's real pipeline.
With estimated ROAS and the click-to-sale funnel, you see which campaign deserves more budget and which one should pause, using your own business's data.

## Frequently asked questions about ads attribution

- **What is the Meta conversions API?** It's the channel Elocuenti uses to send Meta your pipeline's sale events (lead, qualified lead, purchase), so the ad optimizes for real results.
- **Do I have to set up the conversions API by hand?** No. It turns on by itself when you connect WhatsApp; every pipeline stage sends its event with no technical setup on your side.
- **How is estimated ROAS calculated?** With the real sales coming out of each campaign's pipeline, matched against what was spent on those ads.
- **Does it also work with Meta's forms (Lead Ads)?** Yes. Every completed form becomes a contact with its tag and a WhatsApp follow-up template.
- **Does it connect to my ERP, store or CRM?** Shopify, HubSpot, Yango Fleet, Alegra and Siigo connect natively. Any other system you already use connects too, and the agent queries it in real time.
