iPaaS.com has three main experiences (Subscriber, MiSP and Integrator). In the menu in the upper right, you can access the ones you have been granted access to by the iPaaS.com team. As a MiSP, you can also have a subscriber account to use as a sandbox and for testing purposes.
Note: The only MiSP documentation provided here is related to MiSP functionality within the iPaaS.com platform. All remaining functionality is located within PartnerStack.
