### 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

```go
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

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

### Capture authorization

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

### Void authorization

```go
auth, err := c.VoidAuthorization(authID)
```

### Reauthorize authorization

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

### Get Sale by ID

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

### Refund Sale by ID

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

### Get Refund by ID

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

### Get Order by ID

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

```

### Update Order by ID

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

### Authorize Order

```go

```

### Capture Order

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

### Identity

```go
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

    Items: []paypal.PayoutItem{
        paypal.PayoutItem{
