How to connect API for order tracking on Origin theme?

[basicbastardco]

Hi guys, 

I am currently working on building an order tracking page using the Shopify Origin theme. I have implemented all the necessary components and UI elements. However, I am facing some difficulties in connecting with the API to retrieve and display the actual order status.

If you have experience with Shopify and API integrations, I kindly request your assistance in resolving this issue. Your expertise and guidance would be greatly appreciated. Thank you in advance for your help!

I used the below code: 

<div class="order-tracking">
    <div class="input-container">
        <input type="text" id="order_number" class="order-input" placeholder="Order number">
        <button class="order-button" onclick="trackOrder()">TRACK</button>
    </div>
    <div id="order_status"></div>
</div>

<style>
    .order-tracking {
        display: flex;
        flex-direction: column;
        align-items: center;
        margin-bottom: 20px;
    }

    .input-container {
        display: flex;
        align-items: center;
    }

    .order-tracking input.order-input {
        flex-grow: 1;
        text-align: left;
        padding: 1.5rem;
        margin: var(--inputs-border-width);
        transition: box-shadow var(--duration-short) ease, border-color 0.3s; /* Added transition for border color */
        appearance: none;
        background-color: rgb(var(--color-background));
        color: rgb(var(--color-foreground));
        font-size: 13px;
        width: 80%;
        box-sizing: border-box;
        border-radius: var(--inputs-radius);
        height: 4rem;
        min-height: calc(var(--inputs-border-width) * 2);
        min-width: calc(7rem + (var(--inputs-border-width) * 2));
        position: relative;
        border: 0;
        border: 1px solid lightgrey;
        margin-bottom: 13px;
        box-shadow: none; /* Remove the box shadow */
    }

    .order-tracking input.order-input:focus,
    .order-tracking input.order-input:hover {
        outline: none;
        border: 2px solid grey; /* Set the border color to 2px solid grey on hover */
        box-shadow: none; /* Remove the box shadow */
    }

    .order-tracking input.order-input:focus {
        border-color: #282F3D; /* Set the border color to #282F3D on focus */
    }

    .order-tracking button.order-button {
        background-color: #282F3D;
        color: #faf9f6;
        padding: 10px 20px;
        border: none;
        border-radius: 0;
        cursor: pointer;
        width: 30%;
        text-align: center;
        font-size: 11px;
        font-weight: 600;
        margin-left: 2px; /* Added margin to separate the button from the input field */
        height: 4rem; /* Set the height of the button to match the input field */
        margin-bottom: 12px;
    }

    .order-tracking #order_status {
        margin-top: 7px;
        font-weight: bold;
        font-size: 11px !important;
    }
</style>



<script>
    function trackOrder() {
        var orderNumber = document.getElementById("order_number").value;
        var orderStatusDiv = document.getElementById("order_status");

        fetchOrderStatus(orderNumber)
            .then(function (status) {
                orderStatusDiv.innerText = "Order #" + orderNumber + ": " + status;
            })
            .catch(function (error) {
                orderStatusDiv.innerText = "Oops! Something went wrong.";
            });
    }

    function fetchOrderStatus(orderNumber) {
        return new Promise(function (resolve, reject) {
            fetch("/admin/api/2021-09/orders.json?name=" + orderNumber)
                .then(function (response) {
                    if (response.ok) {

                        throw new Error("Oops! Something went wrong.");
                    }
                })
                .then(function (data) {
                    var order = data.orders[0];
                    var status = order.financial_status;

                    if (status) {
                        resolve(status);
                    } else {
                        throw new Error("Oops! Something went wrong.");
                    }
                })
                .catch(function (error) {
                    reject(error);
                });
        });
    }
