My Mautic version is: 4.1.2
My PHP version is: 7.4
My problem is: We are using Spakpost API to send emails via Mautic.
Everything is working fine but Sparkpost Click Tracking is not working for Mautic. They sent me this: Getting Started with Engagement Tracking but I am not sure about how to get this going with Mautic. Does anyone have experience with this and can perhaps point me into the right direction?
Thank you very much.
