Plivo Ruby SDK

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


    Add this line to your application’s Gemfile:

    gem 'plivo', '>= 4.3.0'

    Then execute:

    $ bundle

    Or install it yourself as:

    $ gem install plivo

    For features in beta, use the beta branch:

    $ gem install plivo --pre

    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


    To make API requests, you need to create a RestClient and provide it with authentication credentials, which you can find on the Overview page of the Plivo console.

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

    client =;

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

    client ='your_auth_id', 'your_auth_token');

    The basics

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

    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

    Using client.resources.list lists the first 20 resources by default (the first page, with limit as 20, and offset as 0). Use limit and offset to get more pages of resources.

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

    client.resources.each do |resource|


    Send a message

    require 'rubygems'
    require 'plivo'
    include Plivo
    client =
    message_created = client.messages.create(
      %w[your_destination_number_1 your_destination_number_2],
      'Hello, world!'

    Make a call

    require 'rubygems'
    require 'plivo'
    include Plivo
    client =
    call_made = client.calls.create(

    Generate Plivo XML

    require 'rubygems'
    require 'plivo'
    include Plivo::XML
    response =
    response.addSpeak('Hello, world!')
    puts response.to_xml # Prints the XML string
    xml_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" ?>
      <Speak>Hello, world!</Speak>

    Run a PHLO

    require 'rubygems'
    require 'plivo'
    include Plivo
    client =, AUTH_TOKEN)
    # if credentials are stored in the PLIVO_AUTH_ID and the PLIVO_AUTH_TOKEN environment variables
    # then initialize client as:
    # client =
    # run a phlo:
        #parameters set in PHLO - params
        params = {
           from: '9999999999',
           to: '0000000000'
        response =
        puts response
      rescue PlivoRESTError => e
        puts 'Exception: ' + e.message
