Get Started with .NET Core

Set up your .NET Core dev environment

You must set up and install .NET Core and Plivo’s .NET SDK before you send your first message.

Install .NET Core

You can check whether you already have .NET Framework installed under macOS or Linux and what version is installed by running the command dotnet --version in a terminal window. Under Windows there are several ways to check. If you don’t have it or need a more current version, download and install it.

Install the Plivo .NET SDK

Create a projects directory and change into it.

  $ mkdir mydotnetcoreapp
  $ cd mydotnetcoreapp

Install the Plivo SDK using the .NET CLI.

  $ dotnet new console
  $ dotnet add package Plivo

Once you’ve set up your development environment, you can start sending and receiving messages using PHLO, our visual workflow design studio, or using our APIs and XML documents. Here are three common use cases to get you started.

Send your first outbound SMS/MMS message

You can create and deploy a PHLO to send an outbound text message with just a few clicks on the PHLO canvas, and trigger it with some simple code.

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.

• SMS
• MMS

• 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 API Request trigger state to the Send Message node.

• In the Configuration pane at the right of the canvas, configure the Send Message node with a sender ID in the From field. Enter the destination number you wish to send a message to in the To field. Put your message in the Text field.

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

• If you’d like to send an MMS message, configure the Media URLs field with the media files you’d like 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.

Trigger the PHLO

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. You can define a static payload 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.

In either case, you need your Auth ID and Auth Token, which you can get from the overview page of the Plivo console.

You also need the PHLO ID, which you can copy from the PHLO list page.

With a static payload

When you configure values when creating the PHLO, they act as a static payload.

Code

In Visual Studio, in the CS project, edit Program.cs and paste into it this code.

namespace test_PHLO
{
    class Program
    {
        public static void Main(string[] args)
        {
            var phloClient = new PhloApi("<auth_id>", "<auth_token>"); 
            var phloID = "<phlo_id>";
            var phlo = phloClient.Phlo.Get(phloID);   
            Console.WriteLine(phlo.Run());
        }
    }
}

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console.

With a dynamic payload

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.

Code

In Visual Studio, in the CS project, open the file Program.cs and paste into it this code.

namespace test_PHLO
{
    class Program
    {
        public static void Main(string[] args)
        {
            var phloClient = new PhloApi("<auth_id>", "<auth_token>");
            var phloID = "<phlo_id>";
            var phlo = phloClient.Phlo.Get(phloID); 
            var data = new Dictionary<string, object>
            {
                { "From", "<sender_id>" },
                { "To", "<destination_number>" }

            };  
            Console.WriteLine(phlo.Run(data));
        }
    }
}

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phlo_id placeholder with your PHLO ID from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, +12025551234).

Test

Save the file and run it.

$ dotnet run

Receive your first inbound SMS/MMS message

You can create and deploy a PHLO to receive an SMS text message with a few clicks on the PHLO canvas.

Prerequisite

To receive incoming text messages, you must have an SMS-enabled Plivo phone number. You can rent numbers from the Numbers page of the Plivo console, or by using the Numbers API.

Create the PHLO

• SMS
• MMS

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 HTTP Request 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 HTTP Request node.

• In the Configuration pane at the right of the canvas, configure the HTTP Request node. Specify the address of your web server and specify that from, to, and text fields should be passed along with the request.

• 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 text message to your Plivo phone number and see how the inbound text is handled.

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.

Forward an incoming SMS/MMS message

You can create and deploy a PHLO to forward an incoming message with a few clicks on the PHLO canvas.

• SMS
• MMS

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.

• 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 text message to your Plivo phone number and see how the inbound text is forwarded.
