Python Requests Post Limit

Python Requests is a Python library that allows users to send HTTP/1.1 requests using Python. It is widely used for web scraping, testing, and automation. However, when sending POST requests, there is a limit to how much data can be sent in the request body.

Limitations of POST Requests

The limit on the amount of data that can be sent in a POST request varies depending on the server and the client. Generally, servers have a limit on the maximum size of a POST request, which is usually set to around 2MB. If the payload exceeds this limit, the server may reject the request or return an error code.

In addition, some clients, such as web browsers, also have limits on the amount of data that can be sent in a POST request. For example, Internet Explorer has a default limit of 2MB, while other browsers may have different limits.

Solutions to POST Request Limitations

If you need to send large amounts of data in a POST request, there are several solutions you can try:

  • Chunking: Splitting the data into smaller chunks and sending them in multiple POST requests. This can be done using the "chunked" transfer encoding.
  • GZip Compression: Compressing the data before sending it in the POST request can reduce its size and allow more data to be sent within the limit.
  • Using a Different Method: If the data is too large to be sent in a single POST request, consider using a different HTTP method, such as PUT or PATCH, which may have higher limits.

import requests

url = ''
data = {'key1': 'value1', 'key2': 'value2'}
headers = {'Content-Type': 'application/json'}

# send the data using a POST request
response =, json=data, headers=headers)

# print the response content

In the example above, we are sending a JSON payload in a POST request using the Python Requests library. We set the "Content-Type" header to "application/json" to indicate that we are sending JSON data. If the payload exceeds the limit, the server may return an error code.
