In order to track Facebook Pixel Events like "Donation completed," we need the ability to add a line of javascript (fbq('track', 'Donate');) to the confirmation email or specify a confirmation page to redirect to following a form submission.

This could be solved if we had the ability to insert HTML into a confirmation message or the ability to redirect to a confirmation page on our website (and we can add the javascript to the page via CMS).

As of now, there is no way to attribute any completed donations to our Facebook marketing efforts as we do not have access to OLX's javascript. The Facebook Event Pixel javascript itself needs to be triggered once a form is submitted, not when the form is loaded.
