To authenticate your app and gain access to the Network International (NI) APIs, you will need to obtain an API key and secret. The following steps will guide you through the process of creating and obtaining your API keys:

• To create and obtain API keys, you need to log in to your developer account on the NI API developer portal. From the main menu, click on "My Apps". The My Apps page is where you can manage your NI API applications. To create a new NI Developer Application, click on the "+ Create App" button on the My Apps page.
• In the Create App window, provide a unique name for your app. The app name should be descriptive and easily identifiable. Select the API products that you wish to associate with your app. The API products that you select will determine which NI APIs your app can access. Once you have provided all the required information, click on the "Create App" button to complete the process.
• Once the App is created you can get the consumer key and secret which will be used to authenticate and generate a token for temporary access.
