A cURL command is a compact, portable description of an HTTP request. Converting a tested Postman request to cURL helps you reproduce it in a terminal, a bug report, documentation, or a shell-based workflow.

The FindUtils [Postman to cURL Converter](/developers/postman-to-curl/) reads Postman JSON and generates commands for nested collection requests or a single request. It supports common methods, headers, Bearer and Basic authentication, raw bodies, URL-encoded fields, and multipart form data.

## Before You Export: Remove Secrets

A Postman collection can contain API keys, tokens, passwords, cookies, personal data, and private hostnames. Treat the export as sensitive data.

Before conversion:

- Replace live tokens with clear placeholders.
- Remove cookies and temporary session headers.
- Remove client secrets and passwords.
- Check example request bodies for personal data.
- Review private hostnames before sharing the output.

Use placeholders such as `$API_TOKEN`, `YOUR_API_KEY`, or `https://api.example.com`. Do not paste a secret into a public issue, documentation page, chat, or command history.

## How to Export a Postman Collection

Postman's current export workflow creates a JSON file:

1. Open **Collections** in the Postman sidebar.
2. Open the collection actions menu.
3. Select **More**, then **Export collection**.
4. Select **Export JSON**.

Postman also supports environment and bulk data exports. The request converter needs the collection or request JSON, not a full account dump.

## How to Convert Postman JSON to cURL

### 1. Open the Converter

Go to the [Postman to cURL Converter](/developers/postman-to-curl/).

### 2. Paste or Upload JSON

Paste the collection JSON or upload the exported file. The converter walks nested collection folders and finds each request.

### 3. Choose the Output Style

Keep headers enabled when the server needs content negotiation, authentication, or a body content type. Disable headers only when you deliberately want a minimal request.

Enable long-form flags for documentation. `--header`, `--request`, and `--form` are easier for a new reader than `-H`, `-X`, and `-F`.

### 4. Convert and Review

The tool produces one command for each request. Read every command before you run it.

Check these parts:

- The HTTP method.
- The complete URL and query string.
- Required request headers.
- Authentication values.
- Body encoding.
- File placeholders.

### 5. Copy One Command at a Time

Run a command first against a safe development or test endpoint. Add diagnostic cURL flags only when needed.

```bash
curl --verbose 'https://api.example.com/users'
```

`--verbose` can expose headers and connection details. Remove secrets before you copy its output.

## What the Converter Supports

| Postman data | cURL output |
|---|---|
| GET and other HTTP methods | URL plus `--request` when needed |
| Request headers | `--header` or `-H` |
| Bearer authentication | `Authorization: Bearer …` header |
| Basic authentication | `--user` or `-u` |
| Raw request body | `--data` or `-d` |
| URL-encoded fields | `--data-urlencode` |
| Multipart text fields | `--form` or `-F` |
| Multipart files | `field=@path` placeholder |
| Nested collection folders | One command per request |

## What Needs Manual Work

Postman is more than a request file. It can resolve variables, inherit authentication, run scripts, generate dynamic values, and execute collection logic. A static converter cannot reproduce all of that behavior.

Review these cases manually:

- `{{variable}}` values from environments, collections, or globals.
- Authentication inherited from a parent collection or folder.
- Pre-request scripts and test scripts.
- Dynamic variables and generated signatures.
- OAuth refresh flows.
- Client certificates and proxy settings.
- Files referenced through a local Postman working directory.

Replace unresolved variables before running the command. If a signature depends on a script, create the signature in your target workflow instead of copying a stale value.

## Example Conversion

Postman request data:

```json
{
  "method": "POST",
  "url": "https://api.example.com/users",
  "header": [
    { "key": "Content-Type", "value": "application/json" },
    { "key": "Authorization", "value": "Bearer $API_TOKEN" }
  ],
  "body": {
    "mode": "raw",
    "raw": "{\"name\":\"Ada\"}"
  }
}
```

Readable cURL output:

```bash
curl --request POST 'https://api.example.com/users' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer $API_TOKEN' \
  --data '{"name":"Ada"}'
```

## Verification Checklist

Before you publish or automate a generated command:

- Replace or remove all secrets.
- Confirm the target environment.
- Confirm the HTTP method.
- Confirm body encoding and content type.
- Confirm variable substitution.
- Confirm file paths exist on the target system.
- Run against a safe endpoint.
- Check the response status and body.
- Add failure handling in automation.

For a script, consider `--fail-with-body`, `--show-error`, and a suitable timeout. Read the cURL manual before you add retry behavior to a non-idempotent request.

## FAQ

**Can the converter run the collection?**

No. It generates cURL commands. It does not run Postman scripts, tests, collection order, or environment logic.

**Does it resolve Postman variables?**

No. Replace `{{name}}` placeholders with safe values or shell variables before use.

**Can it convert every request in nested folders?**

Yes. It walks nested `item` arrays and generates a command for each request it finds.

**Should I put a real token in the generated command?**

Avoid it. Use an environment variable or a secure secret store. Shell history and logs can retain literal tokens.
