Twilio provides APIs that allow developers to build voice and text messaging applications. The APIs allow developers to make and receive phone calls, send and receive text messages, buy phone numbers, record messages, and more. Developers can use the APIs by creating a Twilio account, buying a phone number, writing code to integrate with their number, and hosting the application on their own server. Twilio also offers pre-built applications called Twimlets that can be used without hosting code.

- 1. Twilio Infrastructure APIs for building voice and text messaging apps Michael Peacock Twilio Lightning Talk
- 2. Collection of “Infrastructure APIs” supporting: • Make and receive phone calls • Send and receive text messages • Buy phone numbers • Record caller messages • Conference calls • IVR: Interactive Voice Response • DTMF: Gathering number presses • Text to speech Via the web Twilio Lightning Talk
- 3. How does it work? • Create an account • Buy a phone number ($1/month) • Write the code, hosted on your server • Link the application to the phone number • When someone calls the number, twilio hooks into your application which tells it what to do Twilio Lightning Talk
- 4. Writing an application Its all XML <?xml version="1.0" encoding="UTF-8"?> <Response> <Gather numDigits="4" action=“verify.php"> <Say> This is the ACME telephone verification service. To verify your telephone number, please enter the four digit code shown on your screen now. </Say> </Gather> </Response> Twilio Lightning Talk
- 5. Writing an application • <Say> something • <Play> a file • <Gather> digits the caller presses • <Dial> a number to transfer/conference the caller • Send an <Sms> • <Record> what the caller is saying Twilio Lightning Talk
- 6. Writing an application Many of the libraries support generating “TwiML” programatically. E.g. Twilio Lightning Talk
- 7. Application flow At each stage during the call, you define a URL for twilio to redirect to. This allows you to verify details, or act upon a specific request. Twilio Lightning Talk
- 8. Make a call You don’t have to wait for someone to phone you. There is a REST API which allows you to: – Initiate a call from your application – Send an SMS – Buy a phone number Twilio Lightning Talk
- 9. Use cases • Verify a customers phone number – https://github.com/mkpeacock/Phone-Number- Verification • Telephone access to your application – Let customers check the status of their orders • Lead generation – Use a number per lead source and track your marketing efforts – A / B testing on your website (auto-provision a number) • Request a call back form Twilio Lightning Talk
- 10. Costs (its really cheap!) • Phone numbers: $1/month – Inbound calls: 1c/minute – Outbound calls: 2c/minute (landlines) – Outbound calls: 14c/minute (mobiles) • Freephone numbers: $2/month – Inbound calls: 6c/minute Twilio Lightning Talk
- 11. Don’t want to host the code? For pre-defined basic applications (twimlets) which don’t require continuous back and forth between the user and the server, Twilio can host your code. Twilio Lightning Talk
- 12. Twimlets • Call forwarding • Ring upto 5 numbers until one of them answers • Voicemail • Simple menu • Simple message: plays predefined text and audio • Conference calls Twilio Lightning Talk
- 13. Connect Twilio connect lets you build and sell twilio powered applications which then connect to another users twilio account. This lets you sell the application, but lets the buyer pay for their own usage directly. Twilio Lightning Talk
