Generate ready-to-use code from any API request in 15 languages. One click to export, one click to copy.

CODE EXPORT

Overview

Generate ready-to-use code from any request in 15 languages. Click the </> button next to Send to open the code export panel.

Variables are resolved in generated output — {{base_url}} becomes the actual value

Auth headers and params are injected automatically into the generated code

Copy to clipboard with one click — paste directly into your project

No need to send the request first — export works from the current request state

cURL (Windows)	curl CLI	cmd syntax, double-quotes, ^ line continuation
PowerShell	Invoke-WebRequest	PowerShell cmdlet
JavaScript (Fetch)	fetch API	Browser/Node.js fetch API
JavaScript (Axios)	axios	axios library with async/await
Python (Requests)	requests	requests library
Python (http.client)	http.client	stdlib, no dependencies

PHP	cURL extension (curl_*)	cURL extension
Rust	reqwest + tokio	reqwest crate with tokio
Swift	URLSession	Foundation framework
grpcurl	grpcurl CLI	gRPC CLI tool (only for gRPC requests)

How to Export

Five steps from request to code — no need to send the request first:

Build your request

Set the URL, headers, body, and auth as needed

Click the `</>` button

Located in the request builder toolbar, next to the Send button

Select language from dropdown

Choose from 15 languages — your selection is remembered

Code generated instantly

All variables resolved, auth injected, body serialized for the target language

Click 'Copy' to clipboard

Paste directly into your project or terminal

💡 Tip: No need to send the request first — export works from the current request state. Build your request and export immediately.

What's Included in Generated Code

The generated code includes everything needed to reproduce the request:

Resolved URL — variables replaced with actual values from the active environment

HTTP method — GET, POST, PUT, PATCH, DELETE, etc.

All enabled headers — including auth-injected ones (Bearer, Basic, API Key)

Request body — serialized appropriately for the target language

Query parameters — appended to URL or constructed via the language's API

Content-Type header — set based on body type

Comment stripping — inline body comments removed before export

gRPC export: For gRPC requests, the grpcurl output includes -plaintext flag, -proto path, -H metadata headers, and -d message body.

Examples

Given a POST request to https://api.example.com/users with Bearer auth and a JSON body, here's the output in three languages:

cURL (Unix)

curl -X POST 'https://api.example.com/users' \
  -H 'Authorization: Bearer token123' \
  -H 'Content-Type: application/json' \
  -d '{"name":"John"}'

Python (Requests)

import requests

url = "https://api.example.com/users"
headers = {
    "Authorization": "Bearer token123",
    "Content-Type": "application/json"
}
payload = {"name": "John"}

response = requests.post(url, headers=headers, json=payload)
print(response.json())

JavaScript (Fetch)

const response = await fetch("https://api.example.com/users", {
  method: "POST",
  headers: {
    "Authorization": "Bearer token123",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ name: "John" })
});

const data = await response.json();
console.log(data);

CLI Export

Export code from the command line — useful for scripting and CI/CD pipelines:

openpost export curl "Collection" "Request Name" --env production

Outputs generated code to stdout — pipe to a file or clipboard

Variables resolved from the specified environment

Also available via the Management MCP server: export_curl tool
