How to Build RESTful APIs with Django
Building RESTful APIs is a fundamental skill for modern web developers. Django, a high-level Python web framework, provides powerful tools to create robust and scalable APIs quickly. In this guide, we’ll walk through the entire process—from setting up a Django project to deploying a fully functional RESTful API.
Why Django for RESTful APIs?
Django’s "batteries-included" philosophy makes it an excellent choice for API development. With , you get:
First, ensure you have Python installed. Then, create and activate a virtual environment:
bash
Copy
Download
python -m venv venv
source venv/bin/activate # Linux/Mac
venv\Scripts\activate # Windows
Install Django and DRF:
bash
Copy
Download
pip install django djangorestframework
Start a new Django project and app:
bash
Copy
Download
django-admin startproject apiproject
cd apiproject
python manage.py startapp api
Add rest_framework and your app to INSTALLED_APPS in apiproject/settings.py:
python
Copy
Download
INSTALLED_APPS = [
...,
'rest_framework',
'api',
]
Step 2: Creating a Model
Let’s build a simple Task API. In api/models.py, define a Task model:
python
Copy
Download
from django.db import models
class Task(models.Model):
title = models.CharField(max_length=200)
completed = models.BooleanField(default=False)
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
Run migrations to apply the model:
bash
Copy
Download
python manage.py makemigrations
python manage.py migrate
Step 3: Serializing the Model
DRF uses serializers to convert model instances into JSON. Create api/serializers.py:
python
Copy
Download
from rest_framework import serializers
from .models import Task
class TaskSerializer(serializers.ModelSerializer):
class Meta:
model = Task
fields = ['id', 'title', 'completed', 'created_at']
Step 4: Building API Views
Instead of writing individual views for CRUD operations, DRF’s Viewsets simplify the process. In api/views.py:
python
Copy
Download
from rest_framework import viewsets
from .models import Task
from .serializers import TaskSerializer
class TaskViewSet(viewsets.ModelViewSet):
queryset = Task.objects.all()
serializer_class = TaskSerializer
Step 5: Configuring URLs
Use DRF’s routers to auto-generate URLs. Update apiproject/urls.py:
python
Copy
Download
from django.contrib import admin
from django.urls import path, include
from rest_framework.routers import DefaultRouter
from api.views import TaskViewSet
router = DefaultRouter()
router.register(r'tasks', TaskViewSet)
urlpatterns = [
path('admin/', admin.site.urls),
path('api/', include(router.urls)),
]
Step 6: Testing the API
Run the server:
bash
Copy
Download
python manage.py runserver
Now, visit to interact with your API. You can:
Use tools like or for testing.
Step 7: Adding Authentication
To secure your API, DRF supports multiple authentication methods. Let’s enable Token Authentication.
First, install the required package:
bash
Copy
Download
pip install django-rest-framework-simplejwt
Update settings.py:
python
Copy
Download
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': [
'rest_framework_simplejwt.authentication.JWTAuthentication',
],
}
Add JWT routes in urls.py:
python
Copy
Download
from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView
urlpatterns = [
...,
path('api/token/', TokenObtainPairView.as_view(), name='token_obtain_pair'),
path('api/token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
]
Now, only authenticated users can access the API.
Step 8: Deploying the API
For production, deploy using:
Django REST Framework simplifies API development while maintaining flexibility. By following this guide, you’ve built a secure, scalable RESTful API with minimal effort.

Why Django for RESTful APIs?
Django’s "batteries-included" philosophy makes it an excellent choice for API development. With , you get:
Serialization – Convert complex data types (like querysets) into JSON/XML.
Authentication & Permissions – Built-in support for token-based auth, OAuth, and more.
Viewsets & Routers – Reduce boilerplate code for CRUD operations.
Throttling & Pagination – Control request rates and optimize responses.
