Local Development

1. First clone this repository and cd into it.

   git clone git@github.com:TwilioDevEd/marketing-notifications-csharp.git
   cd marketing-notifications-csharp

2. Rename the file MarketingNotifications.Web/Local.config.example to MarketingNotifications.Web/Local.config and update the content.

   You can find your TWILIO_ACCOUNT_SID and TWILIO_AUTH_TOKEN in your Twilio Account Settings. You will also need a TWILIO_NUMBER, which you may find here.

3. Build the solution.

4. Run Update-Database at Package Manager Console to execute the migrations.

   Be sure to ckeck SQLServer 2019 (with LocalDB support) is up and running and the server name matches the one from the connection string on MarketingNotifications.web/Web.config.

5. Run the application.

6. Expose application to the wider internet. To start using ngrok on our project you'll have to execute the following line in the command prompt

   ngrok http 1086 -host-header="localhost:1086"

   Keep in mind that our endpoint is:

   http://<your-ngrok-subdomain>.ngrok.io/Subscribers/Register
   

7. Configure your Twilio number.

Go to your dashboard on Twilio. Click on Twilio Numbers and choose a number to setup. On the phone number page enter the address provided by ngrok into the Messaging Request URL field.

1. Wrap Up!

By now your application should be up and running at http://localhost:1086/. Now your subscribers will be able to text your new Twilio number to subscribe to your Marketing Notifications service.

To subscribe, just send any message to your configured Twilio phone number and it will reply with a text.
