App Inventor 2 - HTTP Requests

[Goundski]

Hi

I am trying to create an Android mobile application using App Inventor 2 (http://appinventor.mit.edu/explore).
I am not an advanced coder at all and have done mostly everything thus far based on self learning and figuring it out as I go.

My issue at hand is that I am trying to utilise the App Inventor 2 - HTTP Request (Non-visible component that provides functions for HTTP GET, POST, PUT, and DELETE requests) to add, delete and view data in my AppGinni webapp.

My AppGini app is very simple setup.
3 Tables: tblPriceList, tblSuppliers, tblProducts
It links as follows. The tblPriceList has a supplier field that links to tblSupplier Name field and a product field that links to tblProduct Name field. Then there are other basic user fields like date, description, price etc.

So if I want to add a product via App Inventor 2 What should I do. I created text boxes and some code as per screenshots.

Okay, I think I may have found the solution in this YouTube video.

I managed to update my AppGini db via mobile app following this video instructions.

Enjoy!
