This is an async library for requesting to the https://nextpay.org purchase gateway.
pip install aionextpay
First import NextPay from aionextpay
from aionextpay import NextPay
Then you need to create an instance from NextPay class and pass it's parameters to it in an async function
from aionextpay import NextPay
token = 'your_nextpay_token'
callback_uri = 'yourdomain.ir/verify'
async def func():
amount = '10000' # price of your product
nextpay = NextPay(token, amount, callback_uri)
Then you need to use purchase function
from aionextpay import NextPay
token = 'your_nextpay_token'
callback_uri = 'yourdomain.ir/verify'
async def func():
amount = '10000' # price of your product
nextpay = NextPay(token, amount, callback_uri)
trans_id = await nextpay.purchase(order_id)
Have in mind that purchase function take kwargs parameter. so read the docs.
If every thing goes good you get a trans_id from that function.
p.s : you have to create a gateway payment with that trans_id and give it to the client like this:
from aionextpay import NextPay
token = 'your_nextpay_token'
callback_uri = 'yourdomain.ir/verify'
async def func():
amount = '10000' # price of your product
nextpay = NextPay(token, amount, callback_uri)
trans_id = await nextpay.purchase(order_id)
link = f"https://nextpay.org/nx/gateway/payment/{trans_id}"
When your client complete the purchase nextpay will request to the address you gave to callback_uri variable
When it does verify the purchase in your request handler like this :
await nextpay.verify(trans_id)
If everything goes good it will return True otherwise an exception will raise
You can also refund the payment like this :
await nextpay.refund(trans_id)
If everything goes good it will return True otherwise an exception will raise
