Authentication to the #ArcGIS #REST #API is handled by providing a #token parameter. There are two ways to obtain tokens: authenticate ArcGIS Online users via #OAuth 2.0 or register your application with ArcGIS Online and make a request for a token with your application's credentials. Tokens obtained with application credentials are limited to accessing premium content and services in ArcGIS Online but are easier to generate. Refer to this comparison of user and application authentication for more in-depth information.
If not fulfilled, you have to install Postman on your computer in order to be able to create, inspect, and debug #HTTP requests.
