# Java SDK

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

## Install

Add to your Maven `pom.xml`:

```xml
<dependency>
  <groupId>com.dropbox.sign</groupId>
  <artifactId>dropbox-sign</artifactId>
  <version>2.x.x</version>
</dependency>
```

Package: [`com.dropbox.sign:dropbox-sign`](https://search.maven.org/artifact/com.dropbox.sign/dropbox-sign) on Maven Central

## Authenticate

Configure the default API client, then instantiate API classes:

```java
import com.dropbox.sign.Configuration;

var apiClient = Configuration.getDefaultApiClient()
    .setApiKey("YOUR_API_KEY");
```

```java
import com.dropbox.sign.Configuration;

var apiClient = Configuration.getDefaultApiClient()
    .setBearerToken("YOUR_ACCESS_TOKEN");
```
