Motivation and Context

How did you test it?

Tested through postman:

• Create a payout through Paypal:

{
    "amount": 1,
    "currency": "EUR",
    "customer_id": "payout_customer",
    "email": "[email protected]",
    "name": "John Doe",
    "phone": "999999999",
    "phone_country_code": "+65",
    "description": "Its my first payout request",
    "payout_type": "wallet",
    "payout_method_data": {
        "wallet": {
            "paypal": {
                "email": "[email protected]"
            }
        }
    },
    "billing": {
        "address": {
            "line1": "1467",
            "line2": "Harrison Street",
            "line3": "Harrison Street",
            "city": "San Fransico",
            "state": "NY",
            "zip": "94122",
            "country": "US",
            "first_name": "John",
            "last_name": "Doe"
        },
        "phone": {
            "number": "8056594427",
            "country_code": "+91"
        }
    },
    "entity_type": "NaturalPerson",
    "recurring": false,
    "metadata": {
        "ref": "123"
    },
    "routing": {
        "type": "single",
        "data": "paypal"
    },
    "confirm": true,
    "auto_fulfill": true
}

• The status should be pending
• Wait for 15+ minutes
• Do a retrieve call to payout

curl --location 'http://localhost:8080/payouts/{{payout_id}}?force_sync=true' \
--header 'api-key: {{apl_key}}'

• The status should be succeeded
