How To Map Web Application To LIFF

Question

I have a project where an insurance company will sell health insurance to an individual client. This client will use a line application to buy the insurance. The payment will come from a mobile wallet from Mobile Network Operator. Below is the process:

 

1. Client login to line

2. Buy insurance using a webform (I don't know how to map webforms to LIFF)

3. Insurance company check LINE userID for mobile money's wallet ID

4. Insurance company request cash out from mobile money's wallet 

 

I am using asp.net webform and C#

 

If anyone can point me in the right direction, I would really appreciate it. Thank you in advance.
