CTWA & Conversion API
The Perfect Partners for Business Messaging
Click-to-WhatsApp Ads (CTWA) are Facebook or Instagram ads designed to open a conversation directly on WhatsApp when clicked. Instead of driving customers to a landing page or website, CTWA instantly launches a WhatsApp chat between your brand and the user.
This instant, familiar interaction increases the chance of conversion and it works because people already love using messaging apps. In fact, according to Kantar, 66% of consumers say they’re more likely to buy from brands that message them directly.
From Social Traffic to Private Leads
CTWA transforms your social media ad clicks into direct, high-intent conversations on WhatsApp instantly. No lead forms, no landing pages, no extra steps. When a user taps your ad, they land in your WhatsApp inbox.
This not only builds a more personal connection, but also gives you the opportunity to turn social traffic into private, owned leads.

Conversions API
Conversions API (CAPI) creates a direct and stable connection between marketing data and Meta platforms. With the ability to pull data from your app, website, physical store, or messaging conversations, Conversions API puts all your data in one place. Offering analytics that provide a full breakdown of your audience data, Conversions API can help you make informed decisions about your marketing strategy that are based on real, concrete data.

The Difference between Facebook Pixel and Conversions API
The Facebook Pixel and Conversions API are both tools provided by Meta to help advertisers track user interactions and measure the effectiveness of their advertising campaigns. However, they differ in their functionality, implementation, and use cases:

The Pixel is ideal for tracking website activity and attributing conversions to specific ad campaigns, while the CAPI provides a more robust solution for tracking offline events, cross-device conversions, and other non-website interactions. Advertisers may choose to use one or both of these tools depending on their tracking needs and objectives.
Remarks: Starting with Graph API version 17 onwards, released on May 23, 2023, Offline Conversions API will no longer support offline events. We anticipate that the Offline Conversions API will be discontinued in the third quarter of 2024. We recommend that advertisers with Offline Conversions API integrations convert their integration into a Conversions API integration and do not update their Offline Conversions API until they have successfully done so.
