Hi, May I know if I would like to develop the integration with our VMS platform with milestone, how can I do? I found some existing integration in Marketplace, like advancis WinGuard PSIM. May I know how they did the integration?

May I ask you what you are trying to do? What do you want to achieve with SDK? Below link is MIP SDK Documentation, I hope this documentation helps you with your inspiration - https://doc.developer.milestonesys.com/html/index.html?base=content_0.html&tree=tree_home.html
