Paypal REST API Bad Request

Question

Пытается проверить платежи Paypal с помощью теста интеграции в проекте grails с использованием песочницы Paypal. На этом этапе я пытаюсь создать Paypal-платеж, используя REST API.

фрагмент кода:

def jsonPaypalPayment =''' 
{ 
    "intent": "sale", 
    "redirect_urls": [{ 
    "return_url": "http://<return URL here>", 
    "cancel_url": "http://<cancel URL here>" 
    }], 
    "payer": { 
    "payment_method": "paypal" 
    }, 
    "transactions": [{ 
    "amount": { 
     "total": "0.10", 
     "currency": "USD", 
    }, 
    "description": "This is the payment transaction description." 
    }] 
} 
''' 

def client = new RESTClient("https://api.sandbox.paypal.com") 
client.contentType = ContentType.JSON 
client.headers.'Authorization' = "${tokenType} ${accessToken}" 
def resp = client.post(path: "/v1/payments/payment", body: jsonPaypalPayment) 

tokenType и маркер доступа успешно получены в предыдущем шаге.

Метод post возвращается с ответом «400 Bad Request». Взял образец запроса из документации с очень незначительными модами.

Полный отладочный вывод:

Я заметил, что REST API находится в бета-версии. Точная документация? Были ли протестированы конечные точки? Когда API REST запланирован к выпуску? Любые идеи относительно плохого запроса? Заранее спасибо.

Answer 1

Прошедший JSON недопустимый (неверный), поскольку кажется, что у вас есть дополнительная запятая после значения currency.

Вот действительный пример, непосредственно из документации:

{ 
    "intent":"sale", 
    "redirect_urls":{ 
     "return_url":"http://<return URL here>", 
     "cancel_url":"http://<cancel URL here>" 
    }, 
    "payer":{ 
     "payment_method":"paypal" 
    }, 
    "transactions":[ 
     { 
     "amount":{ 
      "total":"7.47", 
      "currency":"USD" 
     }, 
     "description":"This is the payment transaction description." 
     } 
    ] 
}
