Do you know the MAKE plataform ? Through MAKE CRM, I only need to make a login with my facebook account, select the page and form which I want to integrate; and anable the "lead acess" to MAKE CRM on my facebook business settings; and then, my scenario on MAKE will receive the lead data when a form is submitted. I would like to learn how to create a similar app to integrate my CRM as the same way, to offer to my customers. Does anyone knows how to do that?
