At its core, setting up a standardized workflow is about enabling your service providers (agents, hosts, customer service reps, administrators, and the rest of the gang) to better serve your customers.
To illustrate a very real-world example, today we'll build a PHP and Laravel webapp for finding and booking vacation properties — tentatively called Airtng.
- A guest requests a reservation for a property
- ホストには予約リクエストを知らせるSMSが受信されます。 ホストは予約を「承諾」または「否認」します
- The guest is notified whether a request was rejected or accepted
We'll be using the Twilio REST API to send our users messages at important junctures. Here's a bit more on our API:
Let's boldly go to the next step! Hit the button below to begin.
Our workflow will require allowing users to create accounts and log-in in order to attempt to reserve properties.
User will need to have a
phone_number which will be required to send SMS notifications later.
Next up, we will create a table that represents a Vacation Rental property.
We're going to need a way to create the property listings for Airtng to be a success.
VacationProperty model belongs to a
User who created it (we'll call this user the host moving forward) and contains only two properties: a
description and an
It has two associations: it has many reservations and many users through those reservations.
Next at the plate: how we will model a reservation.
vacation_propertythe guest is requesting (and associated host)
Since the reservation can only have one guest in this example, we simplified the model by assigning
phone_number directly to the model (but you'll want to move it out).
Our tables are ready, now let's see how we would create a reservation.
The reservation creation form holds only a single field: the message that will be sent to the host user when reserving one of her properties.
The rest of the information necessary to create a reservation is taken from the user that is logged into the system and the relationship between a property and its owner.
A reservation is created with a default status
pending, so when the host replies with a
reject response the system knows which reservation to update.
Let's take a look at how the SMS notification is sent to the host when the reservation is created.
When a reservation is created for a property, we want to notify the owner of that property that someone has requested a reservation.
Now we just have to wait for the host to send an SMS response to 'accept' or 'reject', notify the guest, and update the reservation.
Let's see how we would handle incoming messages from Twilio and accept or reject reservations.
We're zoomed in for a closer look at the
acceptReject method. This method handles our incoming Twilio request and does three things:
- Responds to the host and sends a notification to the guest
In order to route an SMS messages to and from the host, we need to setup Twilio webhooks. The next pane will show you the way.
This method handles the Twilio request triggered by the host's SMS and does three things:
- Checks for a pending reservation from a user
- Responds to the host and sends a notification to the user
In the Twilio console, you should change the 'A Message Comes In' webhook to call your application's endpoint in the route
One way to expose your machine to the world during development is to use ngrok. Your URL for the SMS web hook on your phone number should look something like this:
We'll use the
From parameter to look up the host and check if he or she has any pending reservations. If she does, we'll use the message body to check for the message 'accepted' or 'rejected'. Finally, we update the reservation status and send an SMS to the guest telling them the host accepted or rejected their reservation request.
In our response to Twilio, we'll use Twilio's TwiML to command Twilio to send an SMS notification message to the host.
In the last step, we'll respond to Twilio's request with some TwiML instructing it to send an SMS to both the host and guest.
After updating the reservation status, we must notify the host that he or she has successfully confirmed or rejected the reservation. If the host has no pending reservation, we'll instead return an error message.
If we're modifying a reservation, we'll also send a message to the user who requested the rental delivering the happy or sad news.
We use the Message verb from TwiML to instruct Twilio to send two SMS messages.
Congratulations! We've just automated a rental workflow with Twilio's Programmable SMS, and now you're ready to add it to your own application.
Next, let's take a look at some other easy to add features you might like to add.
