## Getting Started

Here's a general overview of the Lob services available, click through to read more.

- [Postcards API](https://lob.com/products/print-mail/postcards)
- [Letters API](https://lob.com/products/print-mail/letters)
- [Checks API](https://lob.com/products/print-mail/checks)
- [Address Verification API](https://lob.com/products/address-verification)

Please read through the official [API Documentation](#api-documentation) to get a complete sense of what to expect from each endpoint.

### Registration

First, you will need to first create an account at [Lob.com](https://dashboard.lob.com/#/register) and obtain your Test and Live API Keys.

Once you have created an account, you can access your API Keys from the [Settings Panel](https://dashboard.lob.com/#/settings).

### Installation

lob-node can be installed through the npm:

```
$ npm install lob
```

To build and install from the latest source:

```
$ git clone git@github.com:lob/lob-node.git
$ npm install
```

**Requirements:** Node.js >= 24.15.0, npm >= 11.5.1

### Usage
```javascript
const Lob = require('lob')('YOUR API KEY');

// change api version
const Lob = require('lob')('YOUR API KEY', { apiVersion: 'API-VERSION' });

// change internal defaults (e.g. host)
const options = {/* see options below */};
const Lob = require('lob')('YOUR API KEY', options);

// you can also just pass options
const options = { apiKey: 'foo', host: 'bar' };
const Lob = require('lob')(options);

// callback pattern
Lob.addresses.list((err, body) => {
  if (err) return callback(err);
  return callback(null, body.data);
});
```

Additionally, every resource method returns a promise, so you don't have to use the regular callback. E.g.

```javascript
const Lob = require('lob')('YOUR API KEY');

Lob.addresses.list()
.then((res) => {
  console.log(res.data);
})
.catch((e) => {
  console.log(e);
});
```

### Options
The Lob constructor accepts an `options` object which may contain one or more of the following options:

* `apiVersion` - Optionally set the version of the Lob API to use. Defaults to latest.
* `host` - Override the default host API calls are issued to.
* `userAgent` - Override the default userAgent.
* `headers` - Edit the headers sent in all API calls.
* `agent` - Override the default HTTP agent used to make requests.

## Examples

We've provided various examples for you to try out [here](https://github.com/lob/lob-node/tree/master/examples).

There are simple scripts to demonstrate how to create all the core Lob objects (checks, letters, postcards. etc.) as well as more complex examples that utilize other libraries and external files.

### Accessing Response Headers

You can access response headers via a hidden `_response` property.

```javascript
Lob.addresses.list()
.then((res) => {
  res._response.headers['content-type'];
  // => "application/json; charset=utf-8"
});
```

You can also access headers from errors.

```javascript
Lob.addresses.retrieve('adr_bad_id')
.catch((err) => {
  err._response.headers['content-type'];
  // => "application/json; charset=utf-8"
});
```

## API Documentation

The full and comprehensive documentation of Lob's APIs is available [here](https://docs.lob.com/).

## Contributing

To contribute, please see the [CONTRIBUTING.md](https://github.com/lob/lob-node/blob/master/CONTRIBUTING.md) file.

## Testing

To run unit tests with coverage:

```
npm test
```

To run integration tests (requires API keys):

```
TEST_API_KEY=your_test_key npm run test:integration
```

Some integration tests require a live API key:

```
TEST_API_KEY=your_test_key LIVE_API_KEY=your_live_key npm run test:integration
```

To run lint:

```
npm run lint
```

To check for vulnerabilities:

```
npm audit
```

Target: zero `moderate` and zero `high` findings. Current status: **0 vulnerabilities**.
