Before We Begin 

Before creating a Strapi API, it's essential to have specific prerequisites in place to ensure a smooth development process. Here are the vital prerequisites:

  • Node.js and npm: Install Node.js and npm for running Strapi, available from the official Node.js website.

  • Database: Choose and set up a compatible database (SQLitePostgreSQLMySQLMongoDB) and have its connection details ready.

  • Code Editor: Use Visual Studio Code or Sublime Text to write and manage your Strapi project.

  • Strapi CLI: Install the Strapi CLI globally using npm: npm install -g create-strapi.

  • Basic JavaScript Knowledge: A fundamental understanding of JavaScript is essential for server-side scripting in Strapi.

Once you have these prerequisites, you'll be well-prepared to create your Strapi API. 

Step 1. Setting Up Your Strapi API

To embark on your journey of building Strapi API endpoints, you'll first need to set up Strapi on your local machine. Follow these steps to get started:

  • Installation: Begin by installing Node.js and npm if you haven't already. Then, open your terminal and run the following command to install Strapi globally:

npm install -g create-strapi
  • Create a Strapi Project: Use the following command to create a new Strapi project:

create-strapi my-api

Replace "my-api" with your preferred project name.

  • Configuration: Follow the on-screen prompts to configure your Strapi project. 

  • Start the Strapi Development Server: Once the configuration is complete, navigate to your project directory and start the Strapi development server with the following command:

cd my-api
npm run develop

Now that your Strapi project is up and running, it's time to explore how to create Strapi API endpoints.

Step 2. Creating Strapi API Endpoints

Strapi API endpoints are fundamental to developing dynamic web applications with Strapi. These endpoints serve as gateways for accessing and managing your content programmatically.

Now, let's explore how to create them: 

1. Content types and Strapi API

In Strapi, content types are the foundation for your data structures and Strapi API endpoints. These content types define the structure of your Strapi API and are crucial to effective content management. Here's how you can create a new content type in Strapi:

  • Accessing Content-Types Builder: In your Strapi dashboard, navigate to "Plugins" on the left sidebar and select "Content-Types Builder."

  • Create a Content Type: Click the "Create a new content-type" button to start. You can name your content type and define its structure by adding fields like text, date, or media. These fields are the building blocks of your Strapi API.

  • Adding Fields to Your Strapi API: These fields range from simple text inputs to more complex relational data structures. The flexibility of Strapi allows you to design your Strapi API precisely as you want.

Save and Generate Strapi API Endpoints: Once you've configured your content type, save it, and Strapi will automatically generate Strapi API endpoints. 

2. Working with your Strapi API

With your defined content types, you have the foundation for creating Strapi API endpoints that can serve your web application. Strapi offers a straightforward way to make these endpoints without writing extensive code. Here's how to do it:

  • Accessing API Endpoints in Strapi: In your Strapi dashboard, navigate to "Plugins" on the left sidebar and select "API Endpoints."

  • Create a New Strapi API Endpoint: Click the "Create New Endpoint" button. You'll be prompted to select the content type you want to associate with this Strapi API endpoint.

  • Configuring Routes and Permissions: Customize your endpoint's route and configure the actions you want to allow on this endpoint (e.g., create, read, update, delete). Strapi offers a user-friendly interface to set up these permissions, ensuring that your Strapi API is secure and tailored to your needs.

  • Testing Your Strapi API Endpoint: Once you've configured your endpoint, you can try it by making HTTP requests using tools like Postman or simply through your web browser. Your Strapi API is now up and running, ready to serve data to your web application.

Step 3. Interacting with Your Strapi API

Now that you've created your Strapi API endpoints, it's essential to understand how to interact with them using HTTP requests. Strapi follows RESTful API conventions, making it easy to work with. 

Here's a basic overview of how you can perform CRUD (Create, Read, Update, Delete) operations using Strapi API endpoints:

Creating data

You can send a POST request to the corresponding endpoint to add data to your Strapi content type through your Strapi API. For example, if you have a content type called "Article," you can create a new article by sending a POST request to:

POST /articles

Include the required data in the request body in JSON format. Your Strapi API will process the request and store the data in your database.

Reading data

To retrieve data from your Strapi content type through your Strapi API, send a GET request to the corresponding endpoint. For example, to fetch all articles, send a GET request to:

GET /articles

You can also retrieve a specific article by including its ID in the request:

GET /articles/{article_id}

Your Strapi API will respond with the requested data in JSON format, making integrating with your web application easy.

Updating data

To update existing data through your Strapi API, send a PUT or PATCH request to the specific endpoint. For instance, to update an article, send a PUT request to:

PUT /articles/{article_id}

Include the updated data in the request body, and your Strapi API will handle the update process, ensuring that your content remains accurate and up-to-date.

Deleting data 

To delete data through your Strapi API, send a DELETE request to the specific endpoint. For example, to delete an article, send a DELETE request to:

DELETE /articles/{article_id}

Strapi will handle your database operations, making managing your content and data convenient.

Step 4. Advanced Strapi API Development

Strapi offers several advanced features and options for API development, allowing you to tailor your Strapi API to your specific project requirements. Here are some advanced capabilities that Strapi provides:

1. Authentication and Strapi API security

You can implement user authentication and authorization using Strapi's built-in user management system or by integrating third-party authentication providers like OAuth2 or JWT. This ensures that your Strapi API is secure and accessible only to authorized users.

2. Custom controllers and routes 

For more complex functionality, you can create custom controllers and routes to extend your Strapi API's capabilities beyond the basic CRUD operations. This allows you to implement custom business logic and interactions within your Strapi API.

3. Plugins 

Strapi provides a plugin system that allows you to extend its functionality with pre-built or custom plugins. These plugins can add features like image optimization, search functionality, and more, making your Strapi API even more versatile.

4. Webhooks and automation

You can set up webhooks in Strapi to automate actions when specific events occur in your Strapi API. This can be useful for integrating with other services, triggering notifications, or performing background tasks.
