SMS Marketing using PHP

    Overview

    Keeping customers updated of the new offerings and deals about your company aids in the growth of your company. Plivo provides you with a function called SMS marketing to help you do this. In this guide, we’ll show you how to SMS marketing to any phone number.

    Start your implementation with Plivo to SMS Markteing using PHLO or the traditional API way. PHLO allows you to create and deploy your flows using its intuitive canvas in few clicks. Refer to the instructions from the respective tabs below to start your integration with PHLO or API as you wish.

    To implement SMS Marketing use-case, you can create and deploy a PHLO with a few clicks on the PHLO canvas. PHLO also lets you visually construct your entire use-case. With PHLO, you only pay for SMS you send/receive, and building with PHLO is free.

    Implementation

    In this section, we will guide you to create a PHLO to implement SMS marketing use-case.

    Prerequisites

    1. Create a Plivo Account(if you don’t have one already): You can sign up with your work email address and complete the phone verification step using your mobile number.
    2. Buy a Plivo number(optional): You must have a SMS-enabled Plivo phone number if you are willing to receive incoming SMS. You can purchase numbers from the Numbers section of your Plivo Console. It is also possible to purchase numbers using the Numbers API.

    Create the PHLO

    With PHLO, you can quickly create a workflow that suits your use case. To use PHLO, make sure to register and log on to Plivo Console.

    Use the following components to create this PHLO:

    • Send SMS

    When you send an API request to the PHLO, it triggers a SMS message to the user using the Send SMS component. This is a simple use case, yet it is one of the most widely used.

    Note: The Callback function provides the user details required to send the SMS message.

    To create this PHLO

    1. On the top navigation bar, click PHLO. The PHLO page will appear and display your existing PHLOs, if any exist. If this is your first PHLO, then the PHLO page will be empty.
    2. Click CREATE NEW PHLO to build a new PHLO.
    3. In the Choose your use-case window, click Build my own. The PHLO canvas will appear with the Start node. Note: The Start node is the starting point of any PHLO. You can choose between the four available trigger states of the Start node; Incoming SMS, Incoming Call, and API Request. For this PHLO, we will use the API Request trigger state.
    4. Click the Start node to open the Configurations tab and then enter the information to retrieve from the HTTP Request payload. For example, this could be a list of numbers to send an SMS message to.
    5. Click Validate to save the configurations for the node.
    6. From the list of components on the left-hand side, drag and drop the Send SMS component onto the canvas. This will add a Send SMS node onto the canvas.
    7. Connect the Start node with the Send SMS node, using the API Request trigger state.
    8. Rename the node to Send_Notification. Note: You can rename the nodes as per your requirements. We are using specific names to help you relate to the different nodes used in this use case.
    9. Next, configure the Send SMS node to select the From and To numbers from the Start node. Note: The SMS message can be static or dynamic. In this example, we will use a combination of a static message along with some dynamic message.
    10. On the Send SMS Configurations tab, enter a static message (For example, Your order status is: ) in the Message field, followed by a variable to include the dynamic text. You can choose a variable by entering two curly brackets in the Speak Text field. Note:
      • Enter two curly brackets to view all available variables.
      • The values for the From and To numbers are picked from the HTTP Request Payload. Make sure to clearly define the variables in the Start node.
    11. Click Validate to save the configurations for the node.
    12. After you complete the configurations, click Save. You can trigger your PHLO using the PHLO URL to test it out.

    Your complete PHLO will look like this:


    Set up Your PHP Dev Environment

    You must set up and install PHP and Plivo’s PHP SDK for SMS marketing. Here’s how.

    Install PHP

    Operating SystemInstructions
    OS XYou can install PHP using the official installer. You can also install it from here.
    LinuxTo install PHP on Linux you can find the instructions here.
    WindowsTo instll PHP on Windows you can use the official installer.

    Install Composer

    Composer is a dependency manager for PHP that is used in all modern PHP frameworks, such as Symfony and Laravel. We highly recommend using Composer as the package manager for your web project.

    1. Download the latest version of Composer.
    2. Run the following command in Terminal in order to run the composer:

       $ php ~/Downloads/composer.phar --version
      

      Note: PHAR (PHP archive) is an archive format for PHP that can be run on the command line

    3. Run the following command to make it executable:

       $ cp ~/Downloads/composer.phar /usr/local/bin/composer
       $ sudo chmod +x /usr/local/bin/composer
       $ Make sure you move the file to bin directory.
      
    4. To check if the path has /usr/local/bin, use

       $ echo $PATH
      

      If the path is different, use the following command to update the $PATH:

       $ export PATH = $PATH:/usr/local/bin
       $ source ~/.bash_profile
      

      Note: If your PATH doesn’t include /usr/local/bin directory, we recommend adding it so that you can access it globally.

    5. You can also check the version of Composer by running the following command:

       $ composer --version.       
      

    1. Run the following command:

       $ curl -sS https://getcomposer.org/installer | php
      
    2. Run the following command to make the composer.phar file as executable:

       $ chmod +x composer.phar
      

      Note: PHAR (PHP archive) is an archive format for PHP that can be run on the command line

    3. Run the following command to make Composer globally available for all system users:

       $ mv composer.phar /usr/local/bin/composer
      

    1. Download and run the Windows Installer for Composer.

      Note: Make sure to allow Windows Installer for Composer to make changes to your php.ini file.

    2. If you have any terminal windows open, close all instances and open a fresh terminal instance.
    3. Run the Composer command.

       $ composer -V
      

    Install Plivo PHP Package

    • Create a project directory, run the following command:

      $ mkdir myphpapp
      
    • Change the directory to our project directory in the command line:

      $ cd myphpapp
      
    • To install the stable release, run the following command in the project directory:

      $ composer require plivo/plivo-php
      
    • Alternatively, you can download this source and run

      $ composer install
      

    Trigger the PHLO

    Once you have created and setup your Node.js dev envrironment, you can go to your Plivo Consolse and copy the PHLO_ID. You can integrate a PHLO into your application workflow by making an API request to trigger the PHLO with the required payload.

    With Static Payload

    You can choose to either configure the mandatory params required for a PHLO while creating the PHLO itself or, you can pass the params as payload while triggering the PHLO from your app.

    Note: When you configure the params while creating the PHLO, the values(From & To) are hardcoded, and they act as static payload.

    With Static Payload

    Code

    Now, create a file called TriggerPhlo.php and paste the following code:

    1
    2
    3
    4
    5
    6

    <?php
    require 'vendor/autoload.php';
    use Plivo\Resources\PHLO\PhloRestClient;
    use Plivo\Exceptions\PlivoRestException;
    $client = new PhloRestClient("YOUR_AUTH_ID", "YOUR_AUTH_TOKEN");
    
    $phlo = $client->phlo->get("YOUR_PHLO_ID");
    try {
        $response = $phlo->run();
        print_r($response);
    } catch (PlivoRestException $ex) {
        print_r($ex);
    }
    

    With Dynamic Payload

    To use dynamic values for the parameters, follow the below steps.

    • Select the Start node - under API request, fill the Payload key as From & To and keep the values empty, then click validate & save.

    With Dynamic Payload

    • Use the liquid templating params while creating the PHLO and pass the values while triggering the PHLO.

    With Dynamic Payload

    Code

    Now, create a file called TriggerPhlo.php and paste the following code:

    1
    2
    3

    use Plivo\Resources\PHLO\PhloRestClient;
    use Plivo\Exceptions\PlivoRestException;
    $client = new PhloRestClient("YOUR_AUTH_ID", "YOUR_AUTH_TOKEN");
    
    $phlo = $client->phlo->get("YOUR_PHLO_ID");
    try {
        $response = $phlo->run(["From" => "+14157778888", "To" => "+14157778889"]); // These are the fields entered in the PHLO console
        print_r($response);
    } catch (PlivoRestException $ex) {
        print_r($ex);
    }
    

    You can get your Auth_ID and Auth_token from your dashboard AUTHID

    You can find the PHLO_ID on the PHLO Listing page. PHLO Listing

    Test and Validate

    You can save the file and use the below command to run your code.

    $client = new RestClient("<auth_id>","<auth_token>");
    $response = $client->messages->create(
      "+14151234567", #from
      ['+14157654321'], #to
      "Half price clothing today at MB Sports. Offer closes at midnight sharp. No extension. Use code 50off at checkout. Mbsports.com To optout text abcd to 89022",
    );
    print_r($response);
    ?>
    
    Note:
    • Replace the placeholders auth_id & auth_token with your credentials from yourPlivo Console.
    • We recommend that you store your credentials in the auth_id & auth_token environment variables, so as to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and it will automatically fetch them from the environment variables
    • You can use $_ENV or putenv/getenv function to store environment variables and fetch them while initializing the client.
    • Replace the placeholder +14151234567 with the Phone number which you have purchased and +14157654321 with the phone number you will be sending SMS to.
    • Both plivo_source_number and +14157654321 should be in E.164 format
    • For other countries, this can be either a Alpha Sender ID or Numeric Sender ID based on the Sender ID support for the respective countries, to know more you can refer to the Sender ID Usage guide

    Test and Validate

    Once you have created the Send SMS App, You can save the file and use the below command to run your code.

    $ php SendSMS.php
    
    Note: If you are using a Plivo Trial account for this example, you can only send SMS to phone numbers that have been verified with Plivo. Phone numbers can be verified at the Sandbox Numbers page.

    Common Use Cases for SMS Marketing

    You can also use this SMS Marketing structure for other use cases, like Bulk SMS & SMS survey.
