Missing endpoints

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

New Client

import "github.com/plutov/paypal"

// If using Go Modules
// import "github.com/plutov/paypal/v3" 

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

accessToken, err := c.GetAccessToken()

Get authorization by ID

auth, err := c.GetAuthorization("2DC87612EK520411B")

Capture authorization

capture, err := c.CaptureAuthorization(authID, &paypal.Amount{Total: "7.00", Currency: "USD"}, true)

Void authorization

auth, err := c.VoidAuthorization(authID)

Reauthorize authorization

auth, err := c.ReauthorizeAuthorization(authID, &paypal.Amount{Total: "7.00", Currency: "USD"})

Get Sale by ID

sale, err := c.GetSale("36C38912MN9658832")

Refund Sale by ID

// Full
refund, err := c.RefundSale(saleID, nil)
// Partial
refund, err := c.RefundSale(saleID, &paypal.Amount{Total: "7.00", Currency: "USD"})

Get Refund by ID

refund, err := c.GetRefund("O-4J082351X3132253H")

Get Order by ID

order, err := c.GetOrder("O-4J082351X3132253H")

Create an Order

order, err := c.CreateOrder(paypal.OrderIntentCapture, []paypal.PurchaseUnitRequest{paypal.PurchaseUnitRequest{ReferenceID: "ref-id", Amount: paypal.Amount{Total: "7.00", Currency: "USD"}}})

Update Order by ID

order, err := c.UpdateOrder("O-4J082351X3132253H", []paypal.PurchaseUnitRequest{})

Authorize Order

auth, err := c.AuthorizeOrder(orderID, paypal.AuthorizeOrderRequest{})

Capture Order

capture, err := c.CaptureOrder(orderID, paypal.CaptureOrderRequest{})

Identity

token, err := c.GrantNewAccessTokenFromAuthCode("<Authorization-Code>", "http://example.com/myapp/return.php")
// ... or by refresh token
token, err := c.GrantNewAccessTokenFromRefreshToken("<Refresh-Token>")

Retreive user information

userInfo, err := c.GetUserInfo("openid")

Create single payout to email

payout := paypal.Payout{
    SenderBatchHeader: &paypal.SenderBatchHeader{
        EmailSubject: "Subject will be displayed on PayPal",
    },
    Items: []paypal.PayoutItem{
        paypal.PayoutItem{
            RecipientType: "EMAIL",
            Receiver:      "[email protected]",
            Amount: &paypal.AmountPayout{
                Value:    "15.11",
                Currency: "USD",
            },
            Note:         "Optional note",
            SenderItemID: "Optional Item ID",
        },
    },
}

payoutResp, err := c.CreateSinglePayout(payout)

Get payout by ID

payout, err := c.GetPayout("PayoutBatchID")

Get payout item by ID

payoutItem, err := c.GetPayoutItem("PayoutItemID")

Cancel unclaimed payout item by ID

payoutItem, err := c.CancelPayoutItem("PayoutItemID")
