What restrictions should be considered when using REST API?

When using REST API, the following limitations should be considered:

• Stateless: Each request must contain all necessary information; the server does not store state between requests.
• Size limitations: Requests and responses may have size restrictions, especially when using GET requests with URL parameters.
• Rate limiting: Many APIs restrict the number of requests within a certain time frame.
• Idempotency: Some HTTP methods (e.g., GET, PUT, DELETE) should be idempotent, meaning repeated requests should not change the server state.
• Security: Authentication and authorization are necessary, often through tokens (OAuth, JWT).
• Caching: REST API may use caching to improve performance, but this should be considered during design.
• Versioning: When changing the API, it is important to maintain versions to avoid breaking existing clients.

Example: When using a GET request to retrieve data, sensitive information should not be passed in the URL, as it may be cached or logged.
