 ## USOS API
 The USOS API, a cornerstone of academic data access, opens up a world of possibilities for developers seeking to integrate educational information into their applications. Following the OAuth 1.0a workflow as outlined in the official documentation from 'https://apps.usos.edu.pl/developers/api/authorization/', developers can securely implement user authentication and gain authorized access to the wealth of data stored in the USOS system.
 
 The OAuth 1.0a workflow ensures a robust and secure authentication process, safeguarding user credentials while granting seamless access to the USOS API. By adhering to the guidelines provided in the official source, developers can confidently build applications that tap into the extensive educational resources offered by USOS, enriching their projects with academic data in a reliable and user-friendly manner. Explore the possibilities of educational integration through the USOS API and OAuth 1.0a, empowering your applications with a wealth of valuable information.

 ## Scopes
 When you request a Request Token, you may pass the scopes parameter, which describes the things you want the User to share with you. Many API methods require you to have the access to multiple scopes.
 
 When you ask a User to authorize your Request Token, USOS API will notify the User which scopes your application requires. Choose wisely - users may discard your request if you want too much!
