1. Incorporating SMS into your Rails app using Andrew Porterfield @ajporterfield
2. Did you know? • Text messages have a 98% open rate (vs. email’s 20%) • 90% of text messages are read within 3 minutes of delivery • Texting is the most frequently used feature on phones today (more than internet use, voice calls, email, social media, etc)
3. Getting started • Sign up for a free at https://www.twilio.com/try- twilio • Get a local Twilio phone number • Create an API key • Add the twilio-ruby gem to your Gemfile • https://github.com/twilio/twilio-ruby
4. Sending your first SMS # Creating a new client @client = Twilio::REST::Client.new account_sid, auth_token # Or, pre-configure in an initializer Twilio.configure do |config| config.account_sid = account_sid config.auth_token = auth_token end # Then you can create a new client without parameters @client = Twilio::REST::Client.new
5. Sending your first SMS @client.messages.create( from: '+14159341234', # your Twilio number to: '+16105557069', body: ‘indyrb: Reminder that our monthly meetup is tonight @ 7pm at The Speak Easy. See http://bit.ly/1Mozn3q for more details. Reply STOP to cancel.’, )
6. Two-factor authentication • Let’s look at Twitter’s implementation • Getting started with Authy • Sign up through Twilio. • Add the authy-ruby gem to your Gemfile • https://github.com/authy/authy-ruby
7. Authy # config/initializers/authy.rb Authy.api_key = 'your-api-key' Authy.api_uri = ‘https://api.authy.com/' # STEP 1: Register user w/authy response = Authy::API.register_user( email: @user.email, cellphone: @user.phone_number, country_code: 1 ) @user.update(authy_id: response.id)
8. Authy # STEP 2: Send SMS w/token Authy::API.request_sms(id: @user.authy_id) # STEP 3: Verify token response = Authy::API.verify( id: @user.authy_id, token: params[:token] ) if response.ok? sign_in @user redirect_to account_path else flash.now[:error] = 'Incorrect code, please try again' render 'new' end
9. TwiML - Responding to incoming messages
10. TwiML - Responding to incoming messages response = Twilio::TwiML::Response.new do |r| r.Message 'Hello indy.rb!' end puts response.text <?xml version="1.0" encoding="UTF-8"?> <Response> <Message>Hello indy.rb!</Message> </Response>
11. Knock knock jokes • Predictable 4-step format • Twilio acts just like a browser sending a cookie back with each request • Cookie is associated with to/from phone numbers • Go ahead, try it! Text “knock knock” to 317-900-4588. • To the code!
12. Text to give • Giving Tuesday 2015 • Two scenarios 1. New donor 2. Existing donor • More code!
