Host users can offer rental properties which other guest users can reserve. The guest and the host can then anonymously communicate via a disposable Twilio phone number created just for a reservation. In this tutorial, we'll show you the key bits of code to make this work.
To run this sample app yourself, download the code and follow the instructions on GitHub.
The first step in connecting a guest and host is creating a reservation. Here, we handle a form submission for a new reservation which contains the guest's name and phone number.
Part of our reservation system is receiving reservation requests from potential renters. However, these reservations need to be confirmed. Let's see how we would handle this step.
Before the reservation is finalized, the host needs to confirm that the property is still available. Learn how to automate this process in our first AirTNG tutorial, Workflow Automation.
Once the reservation is confirmed, we need to create a Twilio number that the guest and host can use to communicate in the
Once the reservation is confirmed, we need to purchase a Twilio number that the guest and host can use to communicate.
Here we use a Twilio REST API Client to search for and buy a new phone number to associate with the reservation. When we buy the number, we designate a Twilio application that will handle webhook requests when the new number receives an incoming call or text.
We then save the new phone number on our
Reservation model, so when our app receives calls or texts to this number, we'll know which reservation the call or text belongs to.
Now that each reservation has a Twilio Phone Number, we can see how the application will look up reservations as guest or host calls come in.
In our controller, we create a filter which gets executed every time Twilio asks our application how to handle an incoming call or text. This filter finds and stores the correct reservation (the one associated with the anonymous number) as an instance variable that will be used as we connect the guest and host via voice or SMS.
Next, let's see how to connect the guest and the host via SMS.
Our Twilio application should be configured to send HTTP requests to this controller method on any incoming text message. Our app responds with TwiML to tell Twilio what to do in response to the message.
If the initial message sent to the anonymous number was made by the host, we forward it on to the guest. But if the message was sent by the guest, we forward it to the host.
Let's see how to connect the guest and the host via phone call next.
Our Twilio application will send HTTP requests to this method on any incoming voice call. Our app responds with TwiML instructions that tell Twilio to
Play an introductory MP3 audio file and then
Dial either the guest or host, depending on who initiated the call.
That's it! We've just implemented anonymous communications that allow your customers to connect while protecting their privacy with the help of the Twilio Ruby Helper Library.
