Checkout.js and sending message to seller

[Crash1hd]

Hello All,

I have been working with the checkout.js api and everything is working great but for the life of me I am not able to figure out anyway to send a message from my submission form to the sellers account IE "Add special instructions to merchant.".  I have tried using note_to_payee and note_to_payer but I read somewhere that they are deprecated.  I have also tried using custom (it shows up in the callback and works great for showing a msg to the user after submission) kinda useless as I can do that in code anyhow.  Below is an example of what I have.  Any advice would be greatly appreciated.
I ended up using the sku# to pass the message through but that seems illogical to me.

paypal.Button.render({
	env: 'sandbox', // sandbox | production

	client: {
		sandbox:    '....',
		production: '....'
	},

	payment: function(data, actions) {
		return actions.payment.create({
			transactions: [{
				amount: {
					total: parseFloat($("#totalWithShippingPrice").val()),
					currency: 'USD',
					details: {
						subtotal: parseFloat($("#subTotalPrice").val()),
						shipping: parseFloat($("#totalShippingPrice").val()),
					}
				},
				description: 'The payment transaction description.',
				custom: 'Contact us for any questions on your order.',
				payment_options: {
					allowed_payment_method: 'INSTANT_FUNDING_SOURCE'
				},
				soft_descriptor: 'ABC Test',
				item_list: {
					items: [{
						name: 'Name of item',
						description: 'Description of item.',
						quantity: parseFloat($(".quantity").html()),
						price: '14.99',
						sku: $('#os0').val(),//I am currently using this to pass the message through (that seems wrong to me)
						currency: 'USD'
					}],
					shipping_address: {
						recipient_name: $("#fname").val(),
						line1: $("#adr").val(),
						line2: '',
						city: $("#city").val(),
						country_code: $("#countryCode").val(),
						postal_code: $("#postalCode").val(),
						phone: '',
						state: $("#province").val()
					}
				}
			}]
		});
	},
	// Wait for the payment to be authorized by the customer
	onAuthorize: function(data, actions) {
		// Get the payment details
		return actions.payment.get().then(function(data) {
			// Display the payment details and a confirmation button
			var shipping = data.payer.payer_info.shipping_address

			document.querySelector('#sRecipient').innerText = shipping.recipient_name
			document.querySelector('#sLine1').innerText     = shipping.line1
			document.querySelector('#sCity').innerText      = shipping.city
			document.querySelector('#sState').innerText     = shipping.state
			document.querySelector('#sZip').innerText       = shipping.postal_code
			document.querySelector('#sCountry').innerText   = shipping.country_code

			document.querySelector('#paypal-button-container').style.display = 'none'
			document.querySelector('#sConfirm').style.display = 'block'

			// Listen for click on confirm button
			document.querySelector('#sConfirmButton').addEventListener('click', function() {
				// Disable the button and show a loading message
				document.querySelector('#sConfirm').innerText = 'Loading...'
				document.querySelector('#sConfirm').disabled = true

				// Execute the payment

				return actions.payment.execute().then(function() {
					// Show a thank-you note
					document.querySelector('#sThanksname').innerText = shipping.recipient_name
					document.querySelector('#sConfirm').style.display = 'none'
					document.querySelector('#sThanks').style.display = 'block'
					document.querySelector('#sCustom').innerText = data.transactions[0].custom
				})
			})
		})
	}

}, '#paypal-button-container')
