Plivo Ruby SDK

The Plivo Ruby SDK makes it simpler to integrate communications into your Ruby applications using the Plivo REST API. Using the SDK, you will be able to make voice calls, send SMS and generate Plivo XML to control your call flows.

This is to get started with the 4.0.0 version. You can get started with the legacy version here.

Prerequisites

Installation

Add this line to your application’s Gemfile:

gem 'plivo', '>= 4.0.0'

And then execute:

$ bundle

Or install it yourself as:

$ gem install plivo

If you have the 0.3.19 version (a.k.a legacy) already installed, you may have to first uninstall it before installing the new version.

Getting started

Authentication

To make the API requests, you need to create a RestClient and provide it with authentication credentials (which can be found at https://console.plivo.com/dashboard/).

We recommend that you store your credentials in the PLIVO_AUTH_ID and the PLIVO_AUTH_TOKEN environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialise the client with no arguments and it will automatically fetch them from the environment variables:

client = RestClient.new;

Alternatively, you can specifiy the authentication credentials while initializing the RestClient.

client = RestClient.new('your_auth_id', 'your_auth_token');

The basics

The SDK uses consistent interfaces to create, retrieve, update, delete and list resources. The pattern followed is as follows:

client.resources.create(params); # Create
client.resources.get(resource_identifier); # Get
client.resources.update(resource_identifier, params); # Update
client.resources.delete(resource_identifier); # Delete
client.resources.list; # List all resources, max 20 at a time

You can also use the resource directly to update and delete it. For example,

resource = client.resources.get(resource_identifier);
resource.update(params); # update the resource
resource.delete(); # Delete the resource

Also, using client.resources.list would list the first 20 resources by default (which is the first page, with limit as 20, and offset as 0). To get more, you will have to use limit and offset to get the second page of resources.

To list all resources, you can simply use the following pattern that will handle the pagination for you automatically, so you won’t have to worry about passing the right limit and offset values.

client.resources.each do |resource|
  puts resource.id
end

Examples

Send a message

require 'rubygems'
require 'plivo'

include Plivo

client = RestClient.new
message_created = client.messages.create(
  'your_source_number',
  %w[your_destination_number_1 your_destination_number_2],
  'Hello, world!'
)

Make a call

require 'rubygems'
require 'plivo'

include Plivo

client = RestClient.new
call_made = client.calls.create(
  'your_source_number',
  ['your_destination_number'],
  'https://answer.url'
)

Generate Plivo XML

require 'rubygems'
require 'plivo'

include Plivo::XML

response = Response.new
response.addSpeak('Hello, world!')
puts response.to_xml # Prints the XML string

xml_response = PlivoXML.new(response)
puts xml_response.to_xml # Prints XML along with XML version & encoding details

This generates the following XML:

<?xml version="1.0" encoding="utf-8" ?>
<Response>
  <Speak>Hello, world!</Speak>
</Response>
