Configure your prerequisites

There are a few prerequisites that you need to complete before you can work through this tutorial. If you've already completed any of them, feel free to skip that step.

You can create a Vonage account via the Dashboard.

Within the Dashboard you can create Applications and purchase Vonage numbers. You can also perform these tasks using the Nexmo CLI.

If you want to carry out tasks such as creating applications, purchasing Vonage numbers and so on, you will need to install the Nexmo CLI. As the Nexmo CLI requires node.js you will need to install node.js first.

The Nexmo CLI allows you to carry out many operations on the command line. Examples include creating applications, purchasing numbers, and linking a number to an application.

To install the Beta version of the CLI with NPM you can use:

npm install nexmo-cli@beta -g

Set up the Nexmo CLI to use your Vonage API Key and API Secret. You can get these from the settings page in the Dashboard.

Run the following command in a terminal, while replacing api_key and api_secret with your own:

nexmo setup api_key api_secret

If you want to use the Client SDK for Android, you need to install Android Studio.
