What are Meta Conversion APIs (CAPI)?

Meta Conversions API is a tool powered by Meta that collects conversion data from your website or CRM and sends it to Meta's ad system for future optimisation of your ads! With this data, Meta will have an idea of the type of users who generally purchase your products & services and will show ads to similar users with 5x higher chances of conversion. 

But, if you read the title, we didn't talk about the Meta Conversions API for landing page Meta ads. 

Rather, we specifically mentioned how you can use these conversions API for Click to WhatsApp ads!

Meaning ads that run on Facebook and Instagram but click to WhatsApp.

You can easily run these ads using AiSensy's Ads Manager and drive leads to your WhatsApp.

On WhatsApp, there can be multiple events you can consider as conversions and send Meta the signal.

At AiSensy, we term conversion events as

1. Lead acquired or

2. Purchase completed!

In the above image, we have added CAPI to a purchase event as well as a lead gen event requesting callback. 

Based on both of these events, CAPI will send data back to Meta's ad system and further, optimizing your leads, ensuring your ad shows to only quality leads. 

E.g. Let's say you're running a lead generation ad for your real estate company. A user lands on your WhatsApp from an ad and successfully fills out your WhatsApp form. 

For you, the form filled up is the conversion event. 

Here's another example: Let's say you're an ecommerce brand selling your products on WhatsApp using native WhatsApp payments. 

For this, payment completed via WhatsApp payment will be your conversion event. Conversion data of user who successfully purchase your product will go to the meta ads system, and the ad targeting will optimize to find more such leads.  

3. Drag & Drop Conversions API to your Chatbot playground

Connect the CAPIs element after the form fillup component/ WhatsApp payments. So whenever a user successfully fills out a form, that conversion event will be sent to the Meta Ads system, and the ad will optimise to find more such leads. 

That's it!

Meta Conversions API will now take over and send conversion signals to Meta's ad system to further optimise your ads.
