# Losant Ruby REST API Client
[](https://travis-ci.org/Losant/losant-rest-ruby) [](https://badge.fury.io/rb/losant_rest)
The [Losant](https://www.losant.com) REST API client provides a simple way to use the comprehensive Losant API. You can authenticate either as a Losant device or with your user account, and have access to all the functionality of the Losant platform.
This client works with Ruby 2.1 and higher. It uses [HTTParty](https://github.com/jnunemaker/httparty) under the covers for the actual HTTP communication.
## Installation
The latest stable version is available in RubyGems and can be installed using
```bash
gem install losant_rest
```
## Example
Below is a high-level example of using the Losant Ruby REST API client to authenticate against the Losant Platform and report state for a device.
```ruby
require "losant_rest"
response = LosantRest.auth.authenticate_device(credentials: {
deviceId: "my-device-id",
key: "my-app-access-key",
secret: "my-app-access-secret"
})
LosantRest.auth_token = response["token"]
app_id = response["applicationId"]
state = { data: { temperature: AnalogSensor.read } }
response = LosantRest.device.send_state(deviceId: "my-device-id",
applicationId: app_id, deviceState: state)
puts response
# { "success" => true }
```
## API Documentation
### LosantRest
LosantRest is the wrapping module, but it also acts as a singleton [Client](#losantrestclient) instance. So if you only need a single client instance, you do not need to instantiate one yourself - the LosantRest module will act exactly like an instance of LosantRest::Client.
### LosantRest::Client
A client is a single api instance. By default, it is unauthenticated, but can
be given an access token to perform authenticated requests.
#### Initializer
```ruby
LosantRest::Client.new(auth_token: nil, url: "https://api.losant.com")
```
The ``Client()`` initializer takes the following arguments:
* auth_token
The access token to be used for authentication - by default there is no access token. An access token can be acquired through any of the [Auth](docs/auth.md) methods, or can be created for a particular application through [application_api_tokens](docs/applicationApiTokens.md).
* url
The url of the Losant API - by default .
#### Client Accessors
* auth_token
The access token can be accessed or changed after Client creation through this accessor.
* url
The api base url can be accessed or changed after Client creation through this accessor.
#### Resources
Each of the following is a method on the client object, and returns a wrapper for the actions against that particular resource. See each resource documentation file for more information.
