错误：PayPal：必须提供支持：付款

Question

I am running into an issue that I do not completely understand. Following this demo from the PayPal developer site: https://developer.paypal.com/demo/checkout/#/pattern/server

I am running into the error in the title of this post.

Here are some code samples Client side: payment: function () {

        // Make a call to the merchant server to set up the payment

        return paypal.request.post('My/api/call').then(function (res) {

            return res.token;
        });
    },

Server side (my/api/call)

var createdPayment = payment.Create(apiContext);

return createdPayment;

I am using the PayPal-NET-SDK to create these objects and return them to which PayPal seems to be OK with until the response is returned. The demo code from PayPal, I think, implies that a payment object is returned. Which is what I am returning from the server (PayPal gives it an ID, a token, etc from the api call), granted the property name of the token is different. Does anyone have any insight into what may be going on?

Thanks

EDIT: Asa per request here is the payment.Create method

/// <summary>
    /// Creates and processes a payment. In the JSON request body, include a `payment` object with the intent, payer, and transactions. For PayPal payments, include redirect URLs in the `payment` object.
    /// </summary>
    /// <param name="apiContext">APIContext used for the API call.</param>
    /// <returns>Payment</returns>
    public Payment Create(APIContext apiContext)
    {
        return Payment.Create(apiContext, this);
    }

    /// <summary>
    /// Creates (and processes) a new Payment Resource.
    /// </summary>
    /// <param name="apiContext">APIContext used for the API call.</param>
    /// <param name="payment">Payment object to be used in creating the PayPal resource.</param>
    /// <returns>Payment</returns>
    public static Payment Create(APIContext apiContext, Payment payment)
    {
        // Validate the arguments to be used in the request
        ArgumentValidator.ValidateAndSetupAPIContext(apiContext);

        // Configure and send the request
        var resourcePath = "v1/payments/payment";
        var resource = PayPalResource.ConfigureAndExecute<Payment>(apiContext, HttpMethod.POST, resourcePath, payment.ConvertToJson());
        resource.token = resource.GetTokenFromApprovalUrl();
        return resource;
    }

您需要以字符串形式返回EC-XXXXXXX令牌或PAY-XXXXXX id，而不是整个支付对象。
