Python Requests Post Body JSON

If you're working with APIs, sending JSON data as the request body is a common task. Python's requests module makes it easy to send POST requests with JSON data.

Using the json Parameter

The simplest way to send JSON data in a POST request is by using the json parameter. Here's an example:

import requests

data = {"name": "John", "age": 30}
response ="", json=data)


In the above code, we create a dictionary with the data we want to send as JSON. Then we pass that dictionary as the value of the json parameter in the post method. The requests module automatically sets the Content-Type header to application/json.

Using the data Parameter

If you need more control over the headers or if you want to send data in a format other than JSON, you can use the data parameter instead. Here's an example:

import json
import requests

data = {"name": "John", "age": 30}
json_data = json.dumps(data)
headers = {"Content-Type": "application/json"}

response ="", data=json_data, headers=headers)


In the above code, we first convert the data dictionary to a JSON string using the json module's dumps method. Then we create a dictionary of headers with the Content-Type set to application/json. Finally, we pass both the JSON data and headers as values of the data and headers parameters, respectively, in the post method.
