Hey there Mgiara!

Let’s break down the components involved in programmatically changing item prices on a Shopify storefront and understand the relevant APIs and technologies:

  1. Shopify Storefront:

    • A Shopify storefront is the public-facing online store where customers browse and purchase products.
    • It typically includes product listings, product details, a shopping cart, and a checkout process.

  2. Admin API:

    • The Shopify Admin API allows you to interact with the administrative backend of your Shopify store.
    • It provides access to manage products, collections, orders, customers, and other store-related data.
    • You can use the Admin API to change item prices programmatically.

  3. Storefront API:

    • The Shopify Storefront API is designed for building custom, client-side storefronts.
    • It allows you to fetch store data like product information, collections, and customer details.
    • While it’s essential for building custom storefronts, it doesn’t have the capability to directly modify item prices.

  4. Remix:

    • Remix is not a Shopify API; it is a modern framework for building web applications.
    • It’s used for creating interactive and engaging web experiences.
    • You may use Remix alongside Shopify APIs to enhance your storefront, but it doesn’t handle price changes directly.
    • Remix is built on top of React and is used to combine front and backend technologies, simplifying the building process for embedded Shopify apps in general.

  5. App Bridge:

    • Shopify App Bridge is a JavaScript library that helps embedded apps seamlessly integrate into the Shopify Admin.
    • It allows your app to interact with the Shopify Admin without leaving the Shopify environment.
    • Useful if you’re building an app that modifies prices through the admin interface but not directly on the storefront.

  6. Shopify Functions:

    • Shopify Functions is a feature that enables serverless functions to be deployed within Shopify.
    • These functions can be used to customize your storefront’s behavior.
    • While they can enhance your storefront, they are not typically used to change item prices directly.

  7. Multipass:

    • Multipass is a feature that helps with single sign-on (SSO) between your Shopify store and other applications.
    • It’s not directly related to changing item prices on your storefront.

To programmatically change item prices on your Shopify storefront, you’ll primarily want to use the Shopify Admin API. Here’s a high-level overview of the steps involved:

Here is an example of how to authenticate to a Shopify API in Python / Flask with an Access Token in the header of the request. This is a GET and a PUT request, for your edification.

_bp.route('/')
def index():
    return render_template('index.html')

@products_bp.route('/products', methods=['GET'])
def get_all_products():
    # Define the URL for the REST API request
    url = f'https://{SHOP_NAME}.myshopify.com/admin/api/{ADMIN_API_VERSION}/products.json'

    # Headers for the REST API request
    headers = {
        'Content-Type': 'application/json',
        'X-Shopify-Access-Token': ADMIN_API_ACCESS_TOKEN
    }

    # Make the REST API request
    response = requests.get(url, headers=headers)

    # Check if the request was successful
    if response.status_code == 200:
        return jsonify(response.json())
    else:
        return jsonify({'error': 'Unable to fetch products'}), response.status_code

@products_bp.route('/products/
