I have an existing ecommerce android app, in which I need you to implement a few things.
Please follow the instructions and let me know if you can do it.
1. Add a wallet
2. Add referral code system
Referral code amount will be added to referral bonus amount. This amount can be redeemed for shopping as well, but only 50% of this amount can be used at a time for shopping. Also, if the promo code in point number 3 is used, then referral code will not be applied.
3. Add a promo code redeem option using API I'll provide. We'll use this API to check which package the user has bought and accordingly the relative money will be redeemed and added to wallet. For example, I have a package "Gold" which has a value of Rs 4000, then this 4000 will be added to my wallet.
Also, please check the document (PPT) I have attached.
I will give you source code for my android application and APIs. I will not pay until the work is finished, so do not ask for any advance payment. I will not ask for source code until I pay you in full. You can give me only apk file to test until then.
