## Getting help and support

If you are having difficulty using this SDK, or working with the RingCentral
API, please visit our
[developer community forums](https://community.ringcentral.com/spaces/144/) for
help and to get quick answers to your questions. If you wish to contact the
RingCentral Developer Support team directly, please
[submit a help ticket](https://developers.ringcentral.com/support/create-case)
from our developer website.

## Official VS. Community maintained SDKs

This is the **official** RingCentral SDK for the Ruby programming language.
While there are other Ruby SDKs for RingCentral, those are maintained by the
community. We’re including this clarification to help avoid confusion, as some
SDKs have similar names. That said, we truly appreciate and welcome community
contributions and alternative SDKs.

## Installation

```
gem install ringcentral-sdk
```

If for some reason `eventmachine` failed to install, please check
[this](https://stackoverflow.com/a/31516586/862862).

Please note that, there is a gem with a similar name "ringcentral_sdk" which is
not maintained by us. Please make sure that you install the correct gem.

### Name collision with `ringcentral` gem

The `ringcentral` gem is using RingCentral's legacy API which was End-of-Lifed
in 2018. Everyone is recommended to move to the REST API.

If you have both the `ringcentral` and `ringcentral-sdk` gems installed, you
will run into a collision error when attempting to initialize the
`ringcentral-sdk` RingCentral SDK.

The solution is `gem uninstall ringcentral`

## Documentation

https://developer.ringcentral.com/api-docs/latest/index.html

## Usage

```ruby
require 'ringcentral'

rc = RingCentral.new('clientID', 'clientSecret', 'serverURL')
rc.authorize(jwt: 'jwt-token')

# get
r = rc.get('/restapi/v1.0/account/~/extension/~')
expect(r).not_to be_nil
expect('101').to eq(r.body['extensionNumber'])
```

## Samples

For more code samples, please refer to the test cases in `spec` folder.

## How to specify query parameters

### for get & delete

```ruby
rc.get('/restapi/v1.0/account/~/extension', { hello: 'world' })
```

### for post, put & patch

```ruby
rc.post('/restapi/v1.0/account/~/extension/~/sms', payload: body, params: { hello: 'world' })
```

### multi-value query parameter

```ruby
rc.get('/restapi/v1.0/account/~/extension', { hello: ['world1', 'world2'] })
```

Above will be translated to
`/restapi/v1.0/account/~/extension?hello=world1&hello=world2`.

### Token Refresh

Access token expires. You need to call `rc.refresh()` before it expires. If you
want the SDK to do auto refresh please `rc.auto_refresh = true` before
authorization.

### Load pre-existing token

Let's say you already have a token. Then you can load it like this:
`rc.token = your_token_object`. The benefit of loading a preexisting token is
you don't need to go through any authorization flow.

If what you have is a JSON string instead of a Ruby object, you need to convert
it first: `JSON.parse(your_token_string)`.

If you only have a string for the access token instead of for the whole object,
you can set it like this:

```ruby
rc.token = { access_token: 'the token string' }
```

### Send SMS

```ruby
r = rc.post('/restapi/v1.0/account/~/extension/~/sms', payload: {
    to: [{phoneNumber: ENV['RINGCENTRAL_RECEIVER']}],
    from: {phoneNumber: ENV['RINGCENTRAL_SENDER']},
    text: 'Hello world'
})
```

### Send fax

```ruby
rc.post('/restapi/v1.0/account/~/extension/~/fax',
payload: { to: [{ phoneNumber: ENV['RINGCENTRAL_RECEIVER'] }] },
    files: [
        ['spec/test.txt', 'text/plain'],
        ['spec/test.png', 'image/png']
    ]
)
```

### Send MMS

```ruby
r = rc.post('/restapi/v1.0/account/~/extension/~/sms',
    payload: {
        to: [{ phoneNumber: ENV['RINGCENTRAL_RECEIVER'] }],
        from: { phoneNumber: ENV['RINGCENTRAL_SENDER'] },
        text: 'hello world'
    },
    files: [
        ['spec/test.png', 'image/png']
    ]
)
```

## Subscriptions

### WebSocket Subscriptions

```ruby
events = [
  '/restapi/v1.0/account/~/extension/~/message-store',
]
subscription = WS.new(rc, events, lambda { |message|
  puts message
})
subscription.subscribe()
```

#### How to keep a subscription running 24 * 7?

There are two main cases that a subscription will be terminated:

- Absolute time out. The maximum time for a subscription to run is 24 hours.
  After that, the websocket connection will be closed by the server.
- Network issue. It could be your local network issue or the server's network
  issue. In either case, your websocket connection will be closed

In order to keep a subscription running 24 * 7, you need to re-subscribe when
the connection is closed.

```ruby
subscription.on_ws_closed = lambda { |event|
  # make sure that there is no network issue and re-subscribe
  subscription.subscribe()
}
```

## How to test

```
bundle install
```

Rename `.env.sample` to `.env`.

Edit `.env` file to specify credentials.

`RINGCENTRAL_RECEIVER` is a phone number to receive SMS, Fax..etc.

Run `bundle exec rspec`
