How The Plivo — High-Level Objects (PHLO) — Communications System Works

The Plivo System — High-Level Objects (PHLO), pronounced “flow” — is a visual workflow design studio. Usually, it provides building blocks for creating custom voice and SMS applications without writing program code. Instead, you drag and drop components onto a canvas and connect them to create custom workflows. Something that lets you build applications easily and quickly.

With PHLO, you can turn real-time performance into data-driven insights to optimize how you serve your customers. At the same time, the most reliable cloud Contact Center Solution — powered by Plivo’s trusted cloud communications platform — helps you exceed your business customer needs. As well as keep your agents productive and identify coaching opportunities in real-time.

  • Canvas: The canvas is where you place and connect components to create a PHLO. If a PHLO grows to cover the visible canvas, you can scroll the canvas in any direction to declutter the display.
  • Components: Components are PHLO’s building blocks. You drag and drop components to the canvas to create nodes, then connect the nodes to create workflows. You can view a list of all components on the Components Library page.
  • Nodes: A node is an instance of a component placed on the canvas. Each node must have a unique name within the PHLO.
  • States: A component is set to or based on these properties for each action. Each has one input state (at least one output state).

Every node has a set of default configuration values associated with it. When you click on a node, you can view its configuration in the Configuration tab on a panel on the right of the canvas. To view the list of configuration options available for the node, click the Information tab at the top of that panel. It helps display the nodes, default variables, and node-specific options and states.

At the same time, you can also change a node’s configuration by entering values in the Configuration tab. After you make changes, you must validate the node by clicking on Validate at the bottom of the panel. The side panel will display validation errors, if any, or slide off the canvas if the node is validated. Note that you must correct all validation errors before you save the PHLO.

How To Access The Plivo System Platform

When you Sign Up With Plivo, they give you a free trial account and free credits to experiment with and learn about their services. You can Add A Phone Number to your account to start testing the full range of their voice and SMS service features.

The steps to get a free trial account:
  1. First, Sign Up with your work email address.
  2. Secondly, check your inbox for an activation email message from Plivo.
  3. Thirdly, click the link in your email to activate your account.
  4. Next, enter your mobile number to complete the phone verification step.
  5. That’s it! Please get in touch with their Support Team for any assistance.

Afterward, you’ll need the help of the Plivo PHP Server to set up your PHP development environment. You must set up and install PHP and Plivo’s PHP SDK before you send your first message. Please follow the official PHP instructions to download and install PHP on macOSWindows, or Debian Linux, or use your favorite package manager to install PHP on any Linux distro.

Modernize Your Customer Communications Using A PHP Server Environment

Once you’ve set up your development environment, you can send and receive messages using PHLO, their visual workflow design studio, or their APIs and XML documents. You can create and deploy a PHLO to send your first outbound SMS message with a few clicks on the PHLO canvas and trigger it with simple code. Below are a few everyday use cases to help you get started.

  1. To create a PHLO, visit the PHLO Page through the Plivo console.
  2. If this is your first PHLO, the PHLO page will be empty.
  3. Click Create New PHLO.
  4. In the Choose your use case pop-up, click Build My Own.
  5. The PHLO canvas will appear with the Start node.

Note: The Start node is the starting point of any PHLO. It lets you trigger a PHLO to start upon one of three actions: incoming SMS message, incoming, or API request.

How To Create PHLO Environment For Outbound SMS Messages Using Plivo

Note: You can define a static payload by specifying values when you create the PHLO or define a dynamic load by passing values through Liquid Templating Parameters when you trigger the PHLO from your application.

The simple steps to get started:
  • Drag and drop the Send Message component onto the canvas from the list of components on the left-hand side.
  • Remember, when a component is placed on the canvas, it becomes a node.
  • Draw a line to connect the Start node’s API Request trigger state to the Send Message node.
  • Configure the Send Message node with a sender ID in the From field in the Configuration pane at the right of the canvas.
  • Enter the destination number to which you wish to send a message in the To field.
  • Put your message in the Text field provided on the PHLO development environment.
  • If you’d like to send an MMS message, configure the Media URLs field with the files you want to send.
  • Once you’ve configured the node, click Validate to save the configuration.

After you complete the configuration, give the PHLO a name by clicking in the upper left, then click Save. Your PHLO is now ready to test. The next thing is for you to trigger the PHLO environment. Firstly, you integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload — the set of parameters you pass to the PHLO.

Secondly, you can define a static load by specifying values when you create the PHLO or define a dynamic payload by passing values through parameters when you trigger the PHLO from your application. As you can see from the image below, in either case, you need your Auth ID and Token, where you can get an overview page of the Plivo Dashboard Console if you are a beginner builder.

How To Trigger The PHLO Environment Through Plivo

In addition, you also need the PHLO ID, which you can copy from the PHLO List on their official webmaster page. Notwithstanding, when you configure values when creating the PHLO, they act as a static payload. You can visit the Plivo Console to replace the auth placeholders with your authentication credentials. As well as replace the phlo_id placeholder with your PHLO ID.

To use dynamic values for the parameters, use Liquid templating parameters when you create the PHLO and pass the values from your code when you trigger it. This will help you to replace the phone number placeholders with actual phone numbers in E.164 format (for example, +12025551234). Next, save the file and run your code.
