The Facebook (Meta) Conversions API is designed to create a direct connection between your marketing data and Facebook.
This article covers how to set up a Facebook Conversions API access token.
Sign in to your Facebook account
Click 'connect data sources'
Choose your pixel/the pixel you want to implement
Click 'settings'
Find Conversions API and click 'generate access token'
Copy and paste the access token somewhere like a document or draft email. This is important as the number is not stored by Facebook.
Add the access token to your FIXR account by signing in and going to manage account > account settings > advertising. Click 'save changes'.
To use the Conversions API you must have a pixel ID. Find out how to set up a Facebook pixel or where to find your Facebook pixel.
