Basic Understanding of the flow

Hi,

I'm new to visibly and I have some questions:

here is what I'm lookin for, let me know if that is possible

Currently, we are redirecting users from our site to visibly, and ask users to upload presciprtion:

We want to do the following:

Redirect users with a parameter like store.govisibly.com/signup/new?ORDER_ID=1234

And later on, we should get webhook updates for when the test is done to get the status of the test

Is this possible
