Do you want to transfer data to an extremely safe server using cURL POST and using Proxying.io proxies? You’re at the right place!
cURL is another command-line tool that allows making HTTP requests, including POST requests to create or update server resources. With Proxying.io ‘s proxies, you can remain anonymous and avoid annoying geo-blocks.
Let us explore this process and get started.
curl --request POST --data “key=value” https://httpbin.dev/post
Basic cURL POST Request
First, make sure cURL is installed on your system. If not, you can follow the installation steps outlined in How to Use cURL With a Proxy.
In a POST request, a message carries information in the body of the request to a server.
The simple syntax is:
--request POST: Indicates the POST request--data key = value: Transfer information in the request body.- https://httpbin.dev/post: The desired API endpoint.
Make a POST Request with Proxying.io Proxies
Proxies offered by Proxying.io optimize POST requests in terms of anonymity and evasion blockages. Combine proxies through the use of the --proxy flag.
Configure Proxying.io Proxies
Assume your Proxying.io proxy details are:
- Proxy Server: proxy.proxying.io
- Port: 6000
- Username: user
- Password: pwd
So example, with a proxy is:
curl --request POST --proxy http://user:pwd@proxy.proxying.io:6000 --data “key=value” https://httpbin.dev/postSend Different Data Formats
- Plain Text: pass up raw text data plus the Content-Type heading:
curl -X POST -H Content-Type:text/plain -d Hello -p http://user:pws@proxy.proxying.io:6000 https://httpbindev/post- JSON: JSON encoding:
curl -X POST -h “Content-Type: application/json” -d’{“name”:”John”,”age”:”30”}’ -s -Dt -L _H ‘Proxy-Authorization: basic <base64encodeduser:pwd>’- XML: Send an XML data with the proper header:
curl -X POST -H Content-Type: application/xml -d John -D proxy http://user:pwd@proxy.proxying.io:6000 https://httpbin.dev/post- Form Upload: filename, fileupload, formupload: Upload files with
--form:
curl -R POST --form file@/path/to/file.txt -proxy http://user:pwd@proxy.proxying.io:6000 https://httpbin.dev/uploadAuthenticate POST Requests
For APIs requesting authentication, use the --user flag:
curl --request POST --user "username:password" --data "key=value" --proxy http://user:pwd@proxy.proxying.io:6000 https://httpbin.dev/post For security, store credentials in environment variables:
curl --request POST --user "${API_USER}:${API_PASS}" --data "key=value" --proxy http://user:pwd@proxy.proxying.io:6000 https://httpbin.dev/postAdvanced Proxy Features with Proxying.io
Proxying.io’s proxy service offers IP rotation and session persistence, supporting robust scraping and API access.
Maintain Session Persistence
Use a session ID to keep the same proxy IP:
curl --request POST --user "${API_USER}:${API_PASS}" --data "key=value" --proxy http://user:pwd@proxy.proxying.io:6000 https://httpbin.dev/postBypass Proxy for Specific Requests
Disable proxies with --noproxy:
curl --request POST --noproxy "*" --data "key=value" https://httpbin.dev/postKey cURL Options for POST Requests
These are the options for all POST Requests:
1.--data, -d: Transmits data in the request body.
2.--request, -X: Specifies the HTTP method (e.g., POST).
3. -H, -header: Add the user-definable headers (e.g., Content-Type).
4.--form, -F: Posts the form data in a file upload.
5. --user, -u: Gives authentication details.
6. --proxy, -x: Identifies a proxy server.
7. --verbose, -v: Provides request/response information.
8. -o, -output: Save reply to file.
To get all options, runS

cURL POST vs Alternatives
The difference between cURL POST and other alternatives is:
- Postman: A powerful GUI-based tool for testing APIs. It’s beginner-friendly and great for debugging, but lacks the automation and scriptability that cURL offers in a command-line environment
- Python Requests A flexible library used in Python scripts to send HTTP requests. For example:
import requests
response = requests.post("https://httpbin.dev/post", data={"key": "value"}, proxies={"https": "http://user:[email protected]:6000"})Ideal for complex workflows or when integrating with Python codebases, but it requires writing and running Python scripts, hence not always ideal for quick tests or lightweight tasks as cURL.
- Proxying Advantage: cURL is fast, scriptable, and with Proxying.io’s proxies, it supports seamless IP rotation, header control, and authentication in one command.
