# Paubox Node.js SDK

> Send HIPAA-compliant email and submit Paubox Forms from Node.js applications using the official Paubox Node.js SDK.

The Paubox Node.js SDK is the official JavaScript client library for the [Paubox Email API](/email-api) and [Paubox Forms](/forms). All service methods return Promises, making them compatible with `async/await` and promise chains.

```bash theme={null}
npm install --save paubox-node
```

## What you can do

* Send encrypted, HIPAA-compliant email to one or more recipients
* Send batches of up to 50 messages in a single API call
* Create, update, and delete dynamic Handlebars templates
* Send templated messages with per-message variable substitution
* Track delivery status and engagement per recipient
* Retrieve Paubox Form schemas and submit form responses with file attachments

## Requirements

* Node.js v22 or later
