I have many websites of my own and of my clients who are on Systeme.io platform. It is ideal for beginners but becomes limited once a business grows, plus it's like working with something from the 1990s and no AI is available at all. I'm thinking of bringing some sites across to FlexiFunnels but would need to connect their autoresponders to any contact/subscriber forms created on FlexiFunnels. They do have a webhook feature so by question is, can I connect/integrate FlexiFunnels with systeme.io ?
