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

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

    ExpireMonth: "11",
    ExpireYear:  "2020",
    CVV2:        "874",
    FirstName:   "Foo",
    LastName:    "Bar",
})

// Delete it
c.DeleteCreditCard("CARD-ID-123")

// Edit it
c.PatchCreditCard("CARD-ID-123", []paypal.CreditCardField{
    paypal.CreditCardField{
        Operation: "replace",
        Path:      "/billing_address/line1",
        Value:     "New value",
    },
})

// Get it
c.GetCreditCard("CARD-ID-123")

// Get all stored credit cards
c.GetCreditCards(nil)

// Create a webhook
c.CreateWebhook(paypal.CreateWebhookRequest{
    URL: "webhook URL",

        paypal.WebhookEventType{
            Name: "PAYMENT.AUTHORIZATION.CREATED",

Get Invoice Details by ID

// the second argument is an ID, it should be valid
invoice, err := c.GetInvoiceDetails(ctx, "INV2-XFXV-YW42-ZANU-4F33")

• for now, we are yet to implement the ShowAllInvoices endpoint, so use the following cURL request for the same(this gives you the list of invoice-IDs for this customer)

  curl -v -X GET https://api-m.sandbox.paypal.com/v2/invoicing/invoices?total_required=true \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <Token>" 

• refer to the beginning of this Usage section for obtaining a Token.
