# Node SDK

The official Dropbox Sign Node SDK is generated from our [OpenAPI specification](https://github.com/hellosign/hellosign-openapi/blob/main/openapi.yaml) and provides full API coverage.

## Install

```bash
npm install @dropbox/sign
```

Package: [`@dropbox/sign`](https://www.npmjs.com/package/@dropbox/sign) on npm

## Authenticate

Set credentials on each API class you instantiate:

```javascript
import { SignatureRequestApi } from "@dropbox/sign";

const signatureRequestApi = new SignatureRequestApi();
signatureRequestApi.username = "YOUR_API_KEY";
```

```javascript
import { SignatureRequestApi } from "@dropbox/sign";

const signatureRequestApi = new SignatureRequestApi();
signatureRequestApi.accessToken = "YOUR_ACCESS_TOKEN";
```
