Publish your web API to Azure by configuring the Azure SQL connection string, importing the public profile, and deploying with Visual Studio; the deployment completes and opens in the browser.

View data in the Azure secret service by signing into the SQL database with the same admin credentials, access all tables, and prepare to add data in the next section.

Seed data in Azure SQL database by running a script to insert records into the categories and politics tables, preparing the database for consuming restful APIs.

Explore API documentation for ecommerce by importing the API documentation file into Postman and navigating accounts, categories, complaints, products, shopping cart, and orders.

Test register and login endpoints using Postman, supply user data in the request body, and obtain an access token, expiration time, and user ID to access secured endpoints.

Test the categories endpoints by obtaining an access token via login, then call the get categories request with an authorization header to fetch the SQL-based category list.

Explore testing product endpoints, including get product by id, get product by category, and get trending products, and learn to secure requests with access tokens.

test shopping cart endpoints by adding items, checking cart total price, retrieving cart items and item counts, and clearing the cart, using postman requests, access tokens, and user IDs.

Place orders using the place order endpoint with the user access token and details. Then inspect order details, clear the shopping cart, and retrieve orders by user.

Debug a Xamarin.Forms application by deploying to an Android device or emulator, verify the app runs, and learn to test iOS and Android targets, noting mac requirements for iOS debugging.

Learn how the essential preferences plugin stores data in key-value storage and why it’s ideal for simple data like login access tokens, avoiding extra app size and performance costs.

Wire an entry and a button to save the username into preferences using the set method with a key. Retrieve the stored username from preferences in the next lesson.

Retrieve the username from preferences using the get method with the username key and a default value. Display the retrieved value in a label when pressing the retrieve button.

Download the assets folder, switch to the Android project to access Android images, then use the iOS resources folder to work with edited images and continue to the next lesson.

Create account models in the Xamarin Forms e-commerce app, implementing register and login API interactions using Postman and public model classes with properly mapped properties.

Add the middle classes for accounts, categories, and products, and add properties to the category and product classes. Test endpoints with postman, including get product by category and trending product.

Create a model for shopping cart items and subtotal, and configure add-to-cart, get shopping cart items, and clear cart endpoints using Postman in a Xamarin Forms real-world ecommerce app.

Create model classes for orders and complaints in a Xamarin Forms app, wiring Postman endpoints and responses to define order and complaint structures.

Register user method builds a user object with name, email, and password, then posts it as json to the server asynchronously using json.net and http client.

Learn why converting registry class to a static class lets you access the registered user method without an instance, with all methods defined as static, and preview the login method.

Implement a login method to obtain an access token, parse the response, and store the token, expiration time, user id, and username in application preferences.

Create an app settings subclass with a static string field to hold endpoints. Centralize endpoints for register and logging methods to avoid duplication by concatenating endpoints through the settings class.

Fetch categories in a real-world ecommerce app using a bearer token, retrieving the access token from preferences, calling the categories API, and converting the response into category objects.

Develop a get product by id endpoint in a Xamarin forms ecommerce app, wiring a get request in Postman and returning a single product object.

Learn to implement the get product by category endpoint by making a GET request in postman, passing a category ID to return a list of products in that category.

Learn to fetch trending products using a get request with postman. Modify the endpoint and method to return a list of trending products for the Xamarin Forms ecommerce app.

Learn to add items to the cart with a post request, passing cart data to the add to cart endpoint and using an access token in the studio.

Set up an endpoint that accepts a user ID to retrieve the cart subtotal and return the shopping cart total price, using a method that returns a subtotal value.

Learn how to retrieve shopping cart items using a get endpoint in Postman by passing a user id, returning a list of shopping cart items in a Xamarin.Forms app.

Build a get endpoint to return the total items in a user's shopping cart, using Postman and adapting the existing subtotal method in the Xamarin Forms app.
