​
Overview

This guide shows how to receive SMS text messages on a Plivo phone number — something you might want to do to acknowledge a request from a customer, handle opt-ins and opt-outs, or implement an autoresponder application.You can reply to SMS messages either by using our PHLO visual workflow builder or our APIs. Follow the instructions in one of the tabs below.
You can create and deploy a PHLO to forward an incoming message with a few clicks on the PHLO canvas.

How it works

Receive SMS

​
Prerequisites

To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. To receive incoming messages, you must have a Plivo phone number that supports SMS. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.

​
Create the PHLO

To create a PHLO, visit the PHLO page of the Plivo console. If this is your first PHLO, the PHLO page will be empty.
Create a PHLO to forward SMS
  • Click Create New PHLO.
  • In the Choose your use case pop-up, click Build my own. 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 call, or API request.
  • From the list of components on the left-hand side, drag and drop the Send Message component onto the canvas. When a component is placed on the canvas it becomes a node.
  • Draw a line to connect the Start node’s Incoming Message trigger state to the Send Message node.
  • In the Configuration pane at the right of the canvas, configure the Send Message node with the phone number to which you want to forward the message.
  • 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.

​
Assign the PHLO to a Plivo number

Once you’ve created and configured your PHLO, assign it to a Plivo number.
  • On the Numbers page of the console, under Your Numbers, click the phone number you want to use for the PHLO.
  • In the Number Configuration box, select PHLO from the Application Type drop-down.
  • From the PHLO Name drop-down, select the PHLO you want to use with the number, then click Update Number.

You can now send a message to your Plivo phone number and see how the inbound message is forwarded to the phone number you specified.For more information about creating a PHLO application, see the PHLO Getting Started guide.
