How to make your own API in Python

1 min

Here are the basic steps to create your own API in Python:

  1. Choose a web framework to build your API, such as Flask, Django, or FastAPI.
  2. Define the endpoints, or the URLs that the API will respond to, and the methods that will handle the requests and return responses.
  3. Write the functions that will perform the operations required by the endpoints.
  4. Map the functions to the endpoints.
  5. Start the web server and test the API by sending requests to the endpoints.

For example, using Flask:

from flask import Flask, jsonify

app = Flask(__name__)

def hello():
    return "Hello, World!"

def users():
    users = [{"id": 1, "name": "User 1"}, {"id": 2, "name": "User 2"}]
    return jsonify(users)

if __name__ == "__main__":

The code above creates a Flask application with two endpoints: / and /users. The first endpoint returns the text "Hello, World!", and the second endpoint returns a list of user dictionaries in JSON format.

When you run the code and visit, you will get the response [{"id": 1, "name": "User 1"}, {"id": 2, "name": "User 2"}].

Note that this is just a basic example and that building a robust and secure API requires more work, including handling errors, authentication, and authorization.
