Follow the following Steps:

  1. App Integration: Ensure your app is properly integrated into the Shopify store.

  2. App Initialization: Within the product page template (product.liquid or equivalent), initialize the app and its functionalities. Use the necessary JavaScript libraries or SDKs provided by your app to load its features.

  3. Displaying Delivery Estimate: Identify the section of the product page where you want to display the delivery estimate. This might be within a specific

    or a designated area.

  4. Passing Data: Use JavaScript to fetch the estimated delivery dates from your app’s date calculation page. This can involve making AJAX requests to retrieve the calculated delivery date range.

  5. Rendering Delivery Information: Once you’ve fetched the delivery estimate data, use JavaScript to dynamically update the product page’s designated area with the delivery information. You can inject HTML or modify the DOM elements to display the delivery details fetched from your app.

    // Sample code to fetch delivery estimate data and update product page

    // Function to fetch delivery estimate from your app’s date calculation page
    function fetchDeliveryEstimate(productId) {
    // Make an AJAX request to your app’s endpoint to retrieve delivery estimates
    // Use productId to fetch relevant delivery details
    // Upon receiving the response, updateProductPage() with the fetched data
    $.ajax({
    url: ‘/your-app-endpoint’,
    method: ‘GET’,
    data: { productId: productId },
    success: function(response) {
    updateProductPage(response.deliveryInfo);
    },
    error: function(error) {
    console.error(‘Error fetching delivery estimate:’, error);
    }
    });
    }

    // Function to update product page with delivery information
    function updateProductPage(deliveryInfo) {
    // Identify the HTML element where you want to display the delivery estimate
    var deliveryDisplayElement = document.getElementById(‘deliveryEstimateSection’);

    // Update the element’s content with the fetched delivery information
    deliveryDisplayElement.innerHTML = deliveryInfo;
    }

    // Trigger fetchDeliveryEstimate function when the product page loads
    $(document).ready(function() {
    var productId = ‘your_product_id’; // Replace with actual product ID
    fetchDeliveryEstimate(productId);
    });
