Workflow Automation with PHP and Laravel

One of the more abstract concepts you'll handle when building your business is what the workflow will look like.

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.

Here's how it'll work:

A host creates a vacation property listing
A guest requests a reservation for a property
The host receives an SMS notifying them of the reservation request. The host can either Accept or Reject the reservation
The guest is notified whether a request was rejected or accepted

Workflow Building Blocks

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.

User and Session Management

Our workflow will require allowing users to create accounts and log-in in order to attempt to reserve properties.

Each 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.

Vacation Property

We're going to need a way to create the property listings for Airtng to be a success.

The 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 image_url.

It has two associations: it has many reservations and many users through those reservations.

35        Schema::drop('vacation_properties');
36    }

Next at the plate: how we will model a reservation.

Our Reservation Model

The Reservation model is at the center of the workflow for this application. It is responsible for keeping track of:

The guest who performed the reservation
The vacation_property the guest is requesting (and associated host)
The status of the reservation: pending, confirmed, or rejected

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).

39    public function down()
40    {
41        Schema::drop('reservations');
42    }
43}

Our tables are ready, now let's see how we would create a reservation.

Reservation Creation

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 confirm or reject response the system knows which reservation to update.

107        }
108    }
109}

Let's take a look at how the SMS notification is sent to the host when the reservation is created.

Notify the Host

When a reservation is created for a property, we want to notify the owner of that property that someone has requested a reservation.

This is where we use Twilio's Rest API to send an SMS message to the host, using our Twilio phone number. Sending SMS messages using Twilio takes just a few lines of code.

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.

Notify the host of a new reservation request

Let's see how we would handle incoming messages from Twilio and accept or reject reservations.

Handle Incoming Messages

We're zoomed in for a closer look at the acceptReject method. This method handles our incoming Twilio request and does three things:

Checks for a pending reservation from the incoming user
Updates the status of the reservation
Responds to the host and sends a notification to the guest

Accept or reject a reservation logic

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.

Handle Incoming Twilio Requests

This method handles the Twilio request triggered by the host's SMS and does three things:

Checks for a pending reservation from a user
Updates the status of the reservation
Responds to the host and sends a notification to the user

Setting Up Incoming Twilio Requests

In the Twilio console, you should change the 'A Message Comes In' webhook to call your application's endpoint in the route /reservation/incoming:

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:

1http://<subdomain>.ngrok.io/reservation/incoming
2

An incoming request from Twilio comes with some helpful parameters. These include the From phone number and the message Body.

We'll use the From parameter to look up the host and check if they have any pending reservations. If they do, 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.

TwiML Response

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.

TwiML Response

After updating the reservation status, we must notify the host that they have 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.
