# Paubox CLI

> Send HIPAA compliant email and drive Paubox Forms from the terminal or CI pipelines using the Paubox CLI.

The Paubox CLI is a command-line tool for the [Paubox Email API](/email-api) and [Paubox Forms](/forms). Use it to send encrypted email, check delivery status, fetch and submit forms, and manage configuration directly from your terminal, shell scripts, or CI pipelines, with no HTTP client required.

```bash theme={null}
npm install -g paubox-cli
```

## What you can do

* Send encrypted, HIPAA compliant email with a single command
* Check delivery and open status for any sent message
* Retrieve and submit Paubox Forms responses from the terminal
* Store API credentials securely in the OS keychain
* Use `--json` output for scripting and automation
* Set a default sender address so you don't repeat `--from` on every send

## Requirements

* **Node.js** ≥ 20.12.0: [download at nodejs.org](https://nodejs.org)
* **Linux only**: `libsecret-1-dev` is required for OS keychain support. Without it, credentials fall back to `~/.config/paubox/config.json` with `0600` permissions.
