Facebook Conversions API: What You Need to Know
We already know that cookies are disappearing. However, the best alternative solution for this big shift in digital marketing is sometimes unclear. Recently, Facebook launched the Conversion API to offer advertisers another option instead of the pixel to send conversion data. What does this entail and how do you set it up? This article will explain everything you need to know!
What does Conversion API (CAPI) mean? When sending an email address in this data payload or, in some cases, other first party identifiers, Facebook is able to know: “The user that bought a product on your platform is now visiting his Facebook newsfeed on ours,” and therefore serve or not serve ads to this user. So the cookie or IDFA isn’t needed anymore if you send it over through the Conversion API. You can see this API a new road to Facebook, where the customs in between do not look at your cookie for identification, but actively ask for an identification number (which can be a hashed email address).
Now, this doesn’t mean you don’t need the pixel anymore. The Conversion API, as the name already implies, is meant for conversion data first. Site clicks, pageviews, scroll events or other engagement data, is still being sent through the pixel and, therefore, cookie. So don’t delete that tag / pixel just yet! Facebook also uses the pixel to fill in the gaps for conversion data when it doesn’t receive it through the conversion API.
Benefits of the CAPI
- You can do remarketing and ad personalisation. Because you don’t need a third party cookie and you send over your own identifiers of your users, you can still serve personalised ads to users who have already converted, added something to their cart, or other engagement behavior (but note that you first need to ask for a first party identifier from the user).
- Better campaign results. Ad serving optimisation models will be fed with way more data. So predictions to who and when to show ads become much more accurate.
How to set up the Facebook Conversion API
There are multiple options for setting up the CAPI.
New: CAPI-G – Conversion API Gateway
The most recently launched solution from Facebook (October, 2021). Facebook realised how technical implementations can get and that organisations were not making the move to use the Conversion API, so they’ve built a do-it-yourself interface in the Business / Ads Manager where you can walk through some steps to set up your CAPI. This is done by transferring your conversion data to a cloud server in AWS, which you can set up without technical knowledge, which then sends over the data to Facebook through the Conversion API. For companies without a lot of resources, this is an accessible and less costly way to set it up, but do realise that you won’t have the same flexibility as with the third option. The CAPI-G has multiple benefits: speed; cost efficiency; low technical lift, and low maintenance costs.
What is the urgency?
If you don’t implement a solution that’s not so reliant on cookies, you won’t be able to show relevant ads to your customers. Also, your Facebook campaign won’t measure as many conversions anymore which makes the optimisation models perform suboptimal. Facebook is also canceling features like the conversion lift study if you make use of the Facebook Conversion API, which makes sense when you’re not properly tracking conversions. So, to conclude, the urgency is definitely there, and it’s time to start working on non-cookie-reliant solutions like the Facebook Conversion API.
We partnered up with Facebook to help organisations and clients set up the Conversion API. This involves matching the right approach as every organisation is different and has its data stored in a wide range of systems. Don’t hesitate to contact us when you’re not sure on how to set it up, or what method fits your organisation best.
