Missing endpoints

It is possible that some endpoints are missing in this SDK Client, but you can use built-in paypalsdk functions to perform a request: NewClient -> NewRequest -> SendWithAuth

New Client

import "github.com/logpacker/PayPal-Go-SDK"

// Create a client instance
c, err := paypalsdk.NewClient("clientID", "secretID", paypalsdk.APIBaseSandBox)
c.SetLog(os.Stdout) // Set log to terminal stdout

accessToken, err := c.GetAccessToken()

Create direct paypal payment

amount := paypalsdk.Amount{
    Total:    "7.00",
    Currency: "USD",
}
redirectURI := "http://example.com/redirect-uri"
cancelURI := "http://example.com/cancel-uri"
description := "Description for this payment"
paymentResult, err := c.CreateDirectPaypalPayment(amount, redirectURI, cancelURI, description)
