Python-PayPal定期付款-协议明细未显示

Question

In my python project I have to implement paypal recurring payments. I have installed the paypal sdk and created a file to create a PayPal payment page, like this:

import paypalrestsdk
from paypalrestsdk import BillingPlan
from paypalrestsdk import BillingAgreement
from paypalrestsdk import Payment
import webbrowser
from urllib import parse

paypalrestsdk.configure({
    'mode': 'sandbox',  # sandbox or live
    'client_id': <my app client id>,
    'client_secret': <my app secret>})


def create_bill():
    billing_plan = BillingPlan({
        "name": "Plan with Regular and Trial Payment Definitions",
        "description": "Plan with regular and trial payment definitions.",
        "type": "INFINITE",
        "payment_definitions": [
            {
                "name": "Regular payment definition",

                    "value": "100",

                },
                "cycles": "0",
                "charge_models": [

                    }
                }
            ]
        },
        {
            "name": "Trial payment definition",

                    }
                }
            ]
        }

# Create billing plan
if billing_plan.create():
    print("Billing Plan [%s] created successfully" % billing_plan.id)

    # Activate billing plan
    if billing_plan.activate():
        billing_plan = BillingPlan.find(billing_plan.id)
        print("Billing Plan [%s] state changed to %s" % (billing_plan.id, billing_plan.state))
        return billing_plan
    else:
        print(billing_plan.error)
else:
    print(billing_plan.error)


def create_agreement(ret_bil):

    billing_agreement = BillingAgreement({
        "name": "Fast Speed Agreement",
        "description": "Agreement for Fast Speed Plan",
        "start_date": "2018-03-29T00:37:04Z",
        "plan": {
            "id": str(ret_bil.id)
        },
        "payer": {
            "payment_method": "paypal"
        },
        "shipping_address": {
            "line1": "StayBr111idge Suites",
            "line2": "Cro12ok Street",
            "city": "San Jose",
            "state": "CA",
            "postal_code": "95112",
            "country_code": "US"
        }
    })

    if billing_agreement.create():
        # Extract redirect url
        for link in billing_agreement.links:
            if link.method == "REDIRECT":
                # Capture redirect url
                redirect_url = str(link.href)
                # REDIRECT USER TO redirect_url
                webbrowser.open(redirect_url)

    else:
        print(billing_agreement.error)


if __name__ == "__main__":
    create_agreement(create_bill())

But when I run the code above, Paypal starts with agreement description but I can't see the item details and description defined in the BilingPlan (I expected to see the detail about items, trial period, amount, recurrence etc)

Is there something wrong in my code? This is the first time I implement Paypal in my project; have I written my code correctly to implement recurrent payments?

So many Thanks in advance

Answer 1

PayPal will not show the recurring period, amount and service details. You have to show that in your website's page and proceed to PayPal.
