# Install the SDK

Bunny provides server side libraries that abstract much of the authentication, authorization and request formation boilerplate code required to make API requests.

You can find the source code for the two SDKs here:

* [Node SDK](https://github.com/bunnyapp/bunny-node)
* [Ruby SDK](https://github.com/bunnyapp/bunny-ruby)

Installing the SDKs is straighforward.

{% tabs %}
{% tab title="Node.js" %}
Install the Bunny SDK via NPM

```
npm install @bunnyapp/api-client --save
```

Set the access token

```javascript
const Bunny = require("bunny");

const bunny = new Bunny({
  accessToken: "<access-token>",
  baseUrl: "https://<subdomain>.bunny.com"  
});
```

Or alternatively use client credentials. This will enable automatic refresh of expired access tokens.

```javascript
const Bunny = require("bunny");

const bunny = new Bunny({
  clientId: "<bunny-client-id>",
  clientSecret: "<bunny-client-secret>",
  scope: "standard:read standard:write",
  baseUrl: "https://<subdomain>.bunny.com"  
});
```

{% endtab %}

{% tab title="Ruby" %}
Install the Bunny SDK via RubyGems

```
gem install bunnyapp
```

Use Rails generator to create `initializers/bunny_app.rb`

```
bin/rails g bunny_app:install
```

Set access token

```ruby
require 'bunny_app'

BunnyApp.config do |c|
  c.access_token = 'xxx'
  c.base_uri = 'https://<subdomain>.bunny.com'
end
```

Or alternatively use client credentials. This will enable automatic refresh of expired access tokens.

```ruby
require 'bunny_app'

BunnyApp.config do |c|
  c.client_id = 'xxx'
  c.client_secret = 'xxx'
  c.scope = 'standard:read standard:write'
  c.base_uri = 'https://<subdomain>.bunny.com'
end
```

Source: <https://github.com/bunnyapp/bunny-ruby>
{% endtab %}
{% endtabs %}

We recommend using one of our official SDKs, however if you want to write your own code then you will need to [generate an access token and include it in the Authorization header of your GraphQL requests](/developer/using-the-graphql-api/authorizing-api-requests.md). You should also keep in mind handling access token expiry errors and retries.
