RhoConnect REST API
===
The RhoConnect REST API allows you to control, monitor, and debug a running RhoConnect application using a simple HTTP API.

Below we describe the REST API using ruby sample code.

NOTE: All routes that require admin privileges must pass the API token using the special header
 	  'X-RhoConnect-API-TOKEN':api_token_string

## API Errors

All API calls will return http 200 and requested data (if applied). Otherwise, API will return http error code and specific error message in the http message body.

	:::ruby
	def handle_api_error(error_message)
	  @errors ||= []
	  begin
	    yield
	  rescue RestClient::Exception => re
	    if re.response.body.nil? or re.response.body.length == 0
	      @errors << "#{error_message}: [#{re.http_code}] #{re.message}"  
	    else
	      @errors << "#{error_message}: #{re.response.body}"
	    end
	  rescue Exception => e      
	    @errors << "#{error_message}: #{e.message}"
	  end     
	end  

	handle_api_error("Can't get the url of the plugin's backend from the RhoConnect server") do
	  @license_info = JSON.parse(
		RestClient.get(
		  "#{server}/rc/v1/system/appserver", 
	     {'X-RhoConnect-API-TOKEN' => @api_token}
	    ).body
	  )
	end

## System Resource - POST login

	POST /rc/v1/system/login

Before you can use RhoConnect API you should login to the RhoConnect server and get API token:

	:::ruby
	require 'rest_client'
	require 'json'

	server = "http://localhost:9292"
	login = "rhoadmin"
	password = ""

	@api_token = RestClient.post("#{server}/rc/v1/system/login", { :login => login, :password => password }.to_json, :content_type => :json)

## System Resource - POST reset

	POST /rc/v1/system/reset

Reset the server: flush db and re-bootstrap server

	RestClient.post("#{server}/rc/v1/system/reset",
  	  {}.to_json, 
      {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
    )

## System  Resource - GET appserver

	GET /rc/v1/system/appserver

Returns the url of the plugin's backend from the RhoConnect server.

	:::ruby

    ).body

## System Resource - POST appserver

	POST /rc/v1/system/appserver

Saves the url of the plugin's backend to the RhoConnect server.

	:::ruby
	RestClient.post(
	  "#{server}/rc/v1/system/appserver",
      {
        :adapter_url => url
      }.to_json,
      {:content_type => :json,

	  }
	)

Retrieves a list of metric keys matching a given pattern.  This supports 'glob' or '*' style pattern matching.  For example, all metric keys associated with 'Product' source adapter methods:

	:::ruby
	RestClient.get(
	  "#{server}/rc/v1/system/stats",

      :sources => source_name,
      :message => 'hello world',
      :vibrate => 2000,
      :sound => 'hello.mp3'
    }

	RestClient.post(

	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
	)

This will set the refresh time to 100 seconds from the current time.  Calling `set_refresh_time` with no `:refresh_time` will trigger a refresh on the sync request for the source.

## Source Controller - GET partition_type

	  }
	).body

## Source Controller - GET source_id

	GET /rc/v1/sources/:source_id

Return attributes associated with a given source:

* `name` - name of the data source
* `poll_interval` - query poll interval; defines how often RhoConnect will call source adapter to query for new data, set to -1 to disable polling, 0 to always poll
* `partition_type` - to share data across all users, set partition to :app; otherwise use `:user` partition (default)  
* `sync_type` - set to `:bulk_only` to disable `:incremental` sync; regular sync is `:incremental` (default) 
* `queue` - name of the queue for both query and create/update/delete (CUD) jobs (used if no specific queues not specified)
* `query_queue` - name of query queue
* `cud_queue` - name of CUD queue

**NOTE: query or create/update/delete methods of the source adapter will be executed [asynchronously](/rhoconnect/async-jobs) if a queue name is defined.**

	:::ruby
	attributes = RestClient.get("#{server}/rc/v1/sources/<source_id>", 
	  { 
		'X-RhoConnect-API-TOKEN' => @api_token
	  }
	).body

## Source Controller - PUT source_id

	PUT /rc/v1/sources/:source_id

Updates attributes associated with a given source:

`poll_interval` - query poll interval; defines how often RhoConnect will call source adapter to query for new data, set to -1 to disable polling, 0 to always poll.

	:::ruby
	RestClient.put("#{server}/rc/v1/sources/<source_id>", 
	  { 
		:user_name => user,
		:data => {:poll_interval => 25} 
	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
	).body

## Client Resource - GET client_id

	GET /rc/v1/clients/:client_id

Returns client (device) attributes, such as `device_type`, `device_pin`, `device_port`. These attributes are used by [RhoConnect push](/rhoconnect/push). 

	:::ruby
	client_attributes = RestClient.get(
	  "#{server}/rc/v1/clients/<client_id>", 
	  {
	   'X-RhoConnect-API-TOKEN' => @api_token
	  }
	).body

## Client Resource - GET source_id docnames

	GET /rc/v1/clients/:client_id/sources/:source_id/docnames

Returns list of document keys associated with particular client for a given source. These documents are used by the server to sync data with the client. 

	:::ruby
	docs = RestClient.get(
	  "#{server}/rc/v1/clients/:client_id/sources/:source_id/docnames", 
	  { 
		'X-RhoConnect-API-TOKEN' => @api_token
	  }
	).body

## Client Resource - GET source_id doc

	GET /rc/v1/clients/:client_id/sources/:source_id/docs/:doc

Return content of a given source document for the specified client.

	:::ruby
	res = RestClient.get(
	  "#{server}/rc/v1/clients/<client_id>/sources/<source_id>/docs/<docname>", 
	  { 
		'X-RhoConnect-API-TOKEN' => @api_token
	  }
	).body

## Client Resource - POST source_id doc

	POST /rc/v1/clients/:client_id/sources/:source_id/docs/:doc

Sets the content of the specified source document for the given client. Data should be either a string or hash of hashes.
If `append` flag is set to `true` , the data is appended to the current doc (if it exists) instead of replacing it.

	:::ruby
	RestClient.post(
	  "#{server}/rc/v1/clients/<client_id>/sources/<source_id>/docs/<docname>", 
	  { 
		:data => data,
		:append => false
	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
    )

## Plugin source_name - POST push_objects

	POST /app/v1/:source_name/push_objects

Push new objects or object updates to RhoConnect. These changes will be sent to the device the next time it synchronizes.

**NOTE: you may use [ping](/rhoconnect/push) to notify client and trigger sync.**

	:::ruby
	# list of objects in the canonical hash of hashes structure
	data = {
	  '5' => {
	    'name' => 'iPhone'  
	  }
	}
	RestClient.post(
	  "#{server}/app/v1/<source_name>/push_objects", 
	  { 
        :user_id => user_id, 
	    :objects => data 
	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
	)
	
**NOTE: Normally, `push_objects` method will refresh the whole :md document in Redis. However, in case of large-size
documents, `push_objects` method can be optimized by invoking only the necessary updates. This can help reducing
the number of transactions with Redis. To force the optimization, user can use the `:rebuild_md => false` flag
in the `push_objects` parameters hash.**

## Plugin source_name - POST delete_objects

	POST /app/v1/:source_name/push_deletes

Delete objects from RhoConnect. These objects will be deleted from the device the next time it synchronizes.

**NOTE: You may use [ping](/rhoconnect/push) to notify client and trigger sync.**

	:::ruby
	# object_ids is an array of objects to be deleted
	RestClient.post(
	  "#{server}/app/v1/<source_name>/push_deletes", 
	  { 
	    :user_id => user_id, 
	    :objects => object_ids 
      }.to_json, 
     {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
    )

**NOTE: Normally, `push_deletes` method will refresh the whole :md document in Redis. However, in case of large-size
documents, `push_deletes` method can be optimized by invoking only the necessary updates. This can help reducing
the number of transactions with Redis. To force the optimization, user can use the `:rebuild_md => false` flag
in the `push_deletes` parameters hash.**

## Plugin sourece_name - POST fast_insert

	POST /app/v1/:source_name/fast_insert

Push new objects to RhoConnect. Changes are inserted into the Redis set without any checking for previous existence.
This way, the insert is very fast, but user must ensure that the object didn't exist before. No safeguards are implemented. 
Use this method only when you can ensure the integrity of the data.

**NOTE: you may use [ping](/rhoconnect/push) to notify client after the insert and trigger sync.**

	:::ruby
	# list of objects in the canonical hash of hashes structure
	data = {
	  '5' => {
	    'name' => 'iPhone'  
	  }
	}
	RestClient.post(
	  "#{server}/app/v1/<source_name>/fast_insert", 
	  { 
        :user_id => user_id, 
	    :objects => data 
	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
	)
	
## Plugin source_name - POST fast_update

	POST /app/v1/:source_name/fast_update

Push object updates to RhoConnect. This method doesn't involve pulling the existing data out of Redis. Instead it required user to provide the previous state of the data. This way, this method allows for very fast updates (since it just removes the previous data from set and adds new ones). However, no data integrity checks are performed. Therefore, this method must be used only if user can ensure the integrity of the data (i.e. previous state must exist, otherwise it won't be properly deleted). Also, this method can be used to perform fast appends and deletes for any of the object's attributes (However, you shouldn't use this method to remove all of the attributes, `fast_delete` should be used instead.)

**NOTE: you may use [ping](/rhoconnect/push) to notify client after the update and trigger sync.**

	:::ruby
	# list of objects in the canonical hash of hashes structure
	# delete_data contains previous state of the object (to be deleted)
	delete_data = {
	  '5' => {
	    'name' => 'iPhone'  
	  }
	}
	# data contains new state of the object
	# to be inserted
	data = {
	  '5' => {
	    'name' => 'HTC'  
	  }
	}
	RestClient.post(
	  "#{server}/app/v1/<source_name>/fast_update", 
	  { 
        :user_id => user_id, 
	 	:delete_data => delete_data,
	    :data => data 
	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
	)

## Plugin source_name - POST fast_delete

	POST /app/v1/:source_name/fast_delete

Push object deletes to RhoConnect. This method doesn't involve pulling the existing data out of Redis and removing all of its attributes. Instead it requires the user to provide all of the object's data in the hash to be removed. This way, this method allows for very fast deletes (since it just removes the object's data from set). However, no data integrity checks are performed. Therefore, this method must be used only if user can ensure the integrity of the data (i.e. supply all of the object's data to be removed, otherwise some object's data will remain in Redis).

**NOTE: you may use [ping](/rhoconnect/push) to notify client after the delete and trigger sync.**

	:::ruby
	# list of objects in the canonical hash of hashes structure
	# data contains all of the object's data (to be deleted)
	data = {
	  '5' => {
	    'name' => 'iPhone'  
	  }
	}
	RestClient.post(
	  "#{server}/app/v1/<source_name>/fast_delete", 
	  { 
        :user_id => user_id, 
	    :data => data 
	  }.to_json, 
	  {:content_type => :json,
	   'X-RhoConnect-API-TOKEN' => @api_token}
	)
