Can't find why order is being rejected (sb, js)

Posted on

My website takes reservations for "Supertitles" for American orchestras wanting to project text or translations coordinated with sung lyrics. I have gotten my code to work a few times when I have copied examples verbatim, but as soon as I start putting in my own values, I get 400's or 422's. I would like to show you what I have, and see if you can spot where I'm going awry. Here are the values being submitted, followed by my code, which resides in a function called to render the button:

        style: {layout: "vertical", color: "gold", shape: "pill", label: "pay"},
        createOrder: function (data, actions) {
            return actions.order.create({
                purchase_units: [{
                    reference_id: invoice,
                    custom_id: customer,
                    soft_descriptor: "TastefulTitles",
                    amount: {
                        currency_code: "USD",
                        value: total,
                        breakdown: {
                            item_total: {currency_code: "USD", value: subtotal},
                            discount: {currency_code: "USD", value: discount},
                            tax: {currency_code: "USD", value: tax}
                    items: a_itemList,
                    shipping: {
                        method:  "United States Postal Service",
                        name: {full_name: to},
                        address: address
                application_context: {
                    brand_name: "",
                    //shipping_preference: "SET_PROVIDED_ADDRESS",
                    user_action: "PAY_NOW"
        onApprove: function (data, actions) {
            return actions.order.capture().then(function (details) {
                alert("Transaction completed by " +;
                //Call your server to save the transaction
                return fetch("/api/paypal-transaction-complete", {
                    method: "post",
                    headers: {
                        "content-type": "application/json"
                    body: JSON.stringify({
                        orderID: data.orderID

I have omitted the code that builds the objects and fills the variables, as it should be clear from the values shown whether they are properly constructed. For testing I'm using a random number for reference_id, so as not to be submitting repeat orders.


For now, I'm not concerned with the onApprove: code; I'll tackle it once I can get the order correct. There's probably something very simple that should be obvious, but I need some more experienced eyes to find it. Any help will be greatly appreciated!


FWIW, I have a fair amount of experience as a hobbyist programmer, but am relatively new to javascript. This is my first time dealing with js objects.


Can't find why order is being rejected (sb, js)


Can someone please explain why my screenshots have disappeared? No one will be able to help me without their information. Am I in the wrong venue to get an answer to my question?
