The new demand of the app is to connect with Taobao, and then get orders for use and rebate users.
I hope someone who has done it or understands it can tell me about the process here.
I have no idea now...

There are these interfaces here, but now the APP needs a rebate network, which is to purchase, generate orders and pay on the H5 side.
The APP seems to only need authorization and transfer user information to the background.
