Forward Incoming SMS Messages

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

Prerequisites

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.

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.

Test

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.

Here’s how to use Plivo APIs to forward incoming SMS text messages.

How it works

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. If this is your first time using Plivo APIs, follow our instructions to set up a Node.js development environment and a web server and safely expose that server to the internet.

Create an Express server to forward messages

Create a file called forward_sms.js and paste into it this code.

const plivo = require('plivo');
const express = require('express');
const bodyParser = require('body-parser');
const app = express();

app.use(bodyParser.urlencoded({
    extended: true
}));
app.use(function(req, response, next) {
    response.contentType('application/xml');
    next();
});
app.set('port', (process.env.PORT || 3000));
app.all('/forwardsms/', function(request, response) {
    let from_number = request.body.From || request.query.From;
    let to_number = request.body.To || request.query.To;
    let text = request.body.Text || request.query.Text;
    console.log(`Message received details - From: ${from_number}, To: ${to_number}, Text: ${text}`);

    //send the details to generate an XML
    let r = plivo.Response();
    let params = {
        'src': to_number,
        'dst': "<destination_number>",
    };
    let message_body = text;
    r.addMessage(message_body, params);
    console.log(r.toXML());
    response.end(r.toXML());
});
app.listen(app.get('port'), function() {
    console.log('Node app is running on port', app.get('port'));
});

Replace the destination number placeholder with an actual phone number in E.164 format (for example, +12025551234).

Expose your local server to the internet.

Create a Plivo application to forward messages

Associate the Express server you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Give your application a name — we called ours Forward SMS. Enter the server URL you want to use (for example https://<yourdomain>.com/forwardsms/) in the Message URL field and set the method to POST. Click Create Application to save your application.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Forward SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone. The message should be forwarded to the destination number you specified.

Create a Rails controller to forward messages

Change to the project directory and run this command to create a Rails controller to forward incoming messages.

$ rails generate controller Plivo sms

This command generates a controller named plivo_controller in the app/controllers/ directory and a respective view in app/views/plivo. We can delete the view as we don’t need it.

$ rm app/views/plivo/sms.html.erb

Edit app/controllers/plivo_controller.rb and paste this code in the PlivoController class.

include Plivo
include Plivo::Exceptions
include Plivo::XML

class PlivoController < ApplicationController
  skip_before_action :verify_authenticity_token
  def forwardsms
    from_number = params[:From]
    to_number = params[:To]
    text = params[:Text]
    response = Response.new
    params = {
      src: to_number,
      dst: "<destination_number>",
    }
    message_body = text
    response.addMessage(message_body, params)
    xml = PlivoXML.new(response)
    puts xml.to_xml
    render xml: xml.to_xml
  end
end

Replace the destination number placeholder with an actual phone number in E.164 format (for example, +12025551234).

Add a route

Edit config/routes.rb and change the line

Rails.application.routes.draw do
  get 'plivo/sms' 
end

Rails.application.routes.draw do
  post 'plivo/forwardsms/' => 'plivo#forwardsms'
end

Start the Rails server

$ rails server

You should see your basic server application in action at http://localhost:3000/plivo/autoresponder/.

Set up ngrok to expose your local server to the internet.

Note: For ngrok testing, add this line to config/environments/development.rb.
config.hosts << /[a-z0-9-]+\.ngrok\.io/

        );
        $message_body = text;
        $response->addMessage($message_body, $params);

        Header('Content-type: text/xml');
        return $response->toXML();
    }
}

Replace the destination number placeholder with an actual phone number in E.164 format (for example, +12025551234).

Add a route for the forwardsms function and expose your local server to the internet.

Create a Plivo application to forward messages

Associate the Laravel server you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Forward SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone. The message should be forwarded to the destination number you specified.

Overview

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

Prerequisites

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.

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.

Test

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. For information on components and their variables, see the PHLO Components Library.

Here’s how to use Plivo APIs to forward incoming SMS text messages.

How it works

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. If this is your first time using Plivo APIs, follow our instructions to set up a .NET development environment and a web server and safely expose that server to the internet.

Create an MVC controller to forward messages

In Visual Studio, create a new project. Use the template for Web Application (Model-View-Controller).

Give the project a name — we used Forwardsms.

Navigate to the Controllers directory in the Forwardsms project. Create a controller named ForwardsmsController.cs and paste into it this code.

using System;
using System.Collections.Generic;
using Microsoft.AspNetCore.Mvc;

namespace Forwardsms.Controllers
{
    public class ForwardsmsController : Controller
    {
        // GET: /<controller>/
        public IActionResult Index()
        {
            String from_number = Request.Form["From"];
            String to_number = Request.Form["To"];
            String text = Request.Form["Text"];
			Plivo.XML.Response resp = new Plivo.XML.Response();
			resp.AddMessage(text,new Dictionary<string, string>()
			{
				{"src", to_number},
				{"dst", "<destination_number>"},
				{"type", "sms"}
			});
			var output = resp.ToString();
			Console.WriteLine(output);
			return this.Content(output, "text/xml");
		}
    }
}

Replace the destination number placeholder with an actual phone number in E.164 format (for example, +12025551234).

Expose your local server to the internet.

Create a Plivo application to forward messages

Associate the controller you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.

From the Application Type drop-down, select XML Application.

From the Plivo Application drop-down, select Forward SMS (the name we gave the application).

Click Update Number to save.

Test

Send a text message to the Plivo number you specified using any phone. The message should be forwarded to the destination number you specified.

Create a Spring application to forward messages

Use Spring Initializr to create a boilerplate project called Plivo SMS. Open the file PlivoSmsApplication and paste into it this code.

package com.example.Plivo.SMS;

import com.plivo.api.exceptions.PlivoXmlException;
import com.plivo.api.xml.Message;
import com.plivo.api.xml.Response;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class PlivoSmsApplication {

	public static void main(String[] args) {
		SpringApplication.run(PlivoSmsApplication.class, args);
	}
	
	@GetMapping(value = "/forwardsms/", produces = {"application/xml"})
	public String getBody(String From, String To, String Text) throws PlivoXmlException {
		System.out.println(From + " " + To + " " + Text);
		Response res = new Response().children(
				new Message(To, "<destination_number>", Text));
		return res.toXmlString();
	}
}

Replace the destination number placeholder with an actual phone number in E.164 format (for example, +12025551234).

Expose your local server to the internet.

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. If this is your first time using Plivo APIs, follow our instructions to set up a Go development environment and a web server and safely expose that server to the internet.

Create a Go server to forward messages

Create a file called forward_sms.go and paste into it this code.

package main

import (
	"net/http"
	"plivo-go/xml"
)

func handler(w http.ResponseWriter, r *http.Request) {
	fromnumber := r.FormValue("From")
	tonumber := r.FormValue("To")
	text := r.FormValue("Text")
	print("Message Received - ", fromnumber, " ", tonumber, " ", text)

	response := xml.ResponseElement{
		Contents: []interface{}{
			new(xml.MessageElement).
				SetDst("<destination_number>").
				SetSrc(fromnumber).
				SetContents(text),
		},
	}
	w.Write([]byte(response.String()))
}

func main() {
	http.HandleFunc("/forwardsms/", handler)
	http.ListenAndServe(":8080", nil)
}

Replace the destination number placeholder with an actual phone number in E.164 format (for example, +12025551234).

Expose your local server to the internet.

Create a Plivo application to forward messages

Associate the Go server you created with Plivo by creating a Plivo application. Visiting Messaging > Applications and click Add New Application. You can also use Plivo’s Application API.

Assign a Plivo number to your application

Navigate to the Numbers page and select the phone number you want to use for this application.
