Post Body Python Requests

If you are working with APIs or websites that require data transfer, you will need to send HTTP requests. One of the most popular libraries in Python for making HTTP requests is requests. In this article, I will explain how to send a POST request using the requests library in Python.

What is a POST request?

A POST request is used when you need to send data to a server. For example, when you fill out a form on a website and click the submit button, the form data is sent to the server using a POST request.

Sending a POST request with Python Requests

To send a POST request using the requests library, you need to first import it:

import requests

Next, you need to specify the URL that you want to send the POST request to:

url = ''

After that, you need to define the data that you want to send in the request body. This can be done using a dictionary:

data = {'key1': 'value1', 'key2': 'value2'}

Finally, you can send the POST request using the method:

response =, data=data)

The response variable will contain the response from the server.

Using JSON data in a POST request

Sometimes you may want to send JSON data in your POST request. This can be done by specifying the JSON data in the json parameter instead of the data parameter:

import json

json_data = {'key1': 'value1', 'key2': 'value2'}
json_string = json.dumps(json_data)

response =, json=json_string)

Handling headers in a POST request

You may need to include headers in your POST request. Headers can be added using a dictionary:

headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}

response =, headers=headers, json=json_string)


In this article, I have explained how to send a POST request using the requests library in Python. You have learned how to send data in the request body, how to send JSON data, and how to add headers to your requests. With this knowledge, you can start building your own applications and interacting with APIs.
