I am planning to start using Multipass but after reading the documentation, I notice that I need to do a call using an endpoint from the customer's machine, and not from a different origin of request, for instance, a lambda.
I have tested using the remote_ip field in the payload and trying to call the same endpoint from a different IP address, I got an error page. This makes me believe that I cannot create a lambda that will behave in an event that my system throws to authenticate the customer in my Shop but continue with the normal flow and login the customer in my website.
Is there any way to achieve this? Authenticate in my shop but without needing to redirect to the shop and doing this from a different machine?
