How to generate a Facebook / Meta Conversions API access token

Unlike the browser-based Facebook Pixel, which doesn’t require any special authentication to receive data, the Facebook / Meta Conversions API requires an access token to send data.
Here’s how you can generate that token:

Step 1: Go to Events Manager

If you already know your pixel ID, this is the easiest way to get there is to go to the following URL and replace the [INSERT PIXEL ID HERE] with your pixel ID:

https://business.facebook.com/events_manager2/list/pixel/[INSERT PIXEL ID HERE]/overview

If you don’t know your pixel ID, you can find it through the lefthand flyout menu like this by clicking on “Events Manager” and, from there, “Settings”:

Step 2: Generate the token

Once you’re in the Events Manager settings for your pixel, scroll almost all the way down to find the “Set up manually” section with the tiny link “Generate access token”:

Click it and you’ll be given the token which you should copy and paste into your application or pass on to your developer.
