A quick segue into some exciting and relevant theories about the FDK you used to build your first app. When you run the FDK using the fdk run command, it creates a local server and serves your app over it on port :10001. Each Freshworks product can render this app served on your localhost on any page the app configures to be displayed by just appending ?dev=true to the URL.
While the first app you built did not use them, it is worth knowing that apps can also consume REST APIs. Most integrations you build will require this. For example, you can programmatically create contacts on Freshdesk or view an appointment on Freshsales Suite. Each product has its own set of REST APIs that any app can consume as a client.
For now, we will leave you with that tidbit and come back to this a little later!
