Set up

Requirements

• .NET Framework
• A Twilio account - sign up
• ngrok

Twilio Account Settings

This application should give you a ready-made starting point for writing your own application. Before we begin, we need to collect all the config values we need to run the application:

Config Value	Description
Account Sid	Your primary Twilio account identifier - find this in the Console.
Auth Token	Used to authenticate - just like the above, you'll find this here.

Local development

After the above requirements have been met:

1. Clone this repository and cd into it

git clone [email protected]:TwilioDevEd/send-sms-during-inbound-calls-csharp.git
cd send-sms-during-inbound-calls-csharp

2. Set your configuration variables

copy TwilioApp/Local.config.example TwilioApp/Local.config

See Twilio Account Settings to locate the necessary environment variables.

3. Build the solution

4. Run the application

5. Expose the application to the wider Internet using ngrok.

$ ngrok http 49341 -host-header="localhost:49341"

Or, use ngrok Extensions for Visual Studio. Select "Tools... Start ngrok Tunnel".

6. Configure Twilio to call your webhooks

You will need to configure Twilio to call your application when calls are received in your Twilio Number. The voice url should look something like this:

https://<your-ngrok-subdomain>.ngrok.io/answer

7. Make a call to your number.

That's it!
