What’s a common best practice when designing RESTful APIs?
REST API Must Accept and Respond with JSON
It is a common practice that APIs should accept JSON requests as the payload and also send responses back. JSON is a open and standardized format for data transfer. It is derived from JavaScript in a way to encode and decode JSON via the Fetch API or another HTTP client.
What is the best way to secure Web API?
For security concerns, it is recommended that the Web APIs should use the HTTPS (HTTP secure) endpoints to ensure that the data communication is encrypted using TLS/SSL (Transport Layer Security). By the way, SSL is a cryptographic protocol responsible for ensuring secure communication over a computer network.
How do you secure a REST service?
How do you secure a REST API? The first step in securing an API is to ensure that you only accept queries sent over a secure channel, like TLS (formerly known as SSL). Communicating with a TLS certificate protects all access credentials and API data in transit using end-to-end encryption.
What are the 5 principles for a RESTful API?

What kind of authentication works best for a web service that needs to be secure yet easy to implement across different programming languages?
Always use TLS
Every web API should use TLS (Transport Layer Security). TLS protects the information your API sends (and the information that users send to your API) by encrypting your messages while they’re in transit.
Which three methods can be used to authenticate to an API?
We’ll highlight three major methods of adding security to an API — HTTP Basic Auth, API Keys, and OAuth. We’ll identify the pros and cons of each approach to authentication, and finally recommend the best way for most providers to leverage this power.
Authentication is stating that you are who are you are and Authorization is asking if you have access to a certain resource. When working with REST APIs you must remember to consider security from the start. RESTful API often use GET (read), POST (create), PUT (replace/update) and DELETE (to delete a record).
