API Terminology

• Idempotency: In the context of REST APIs, when making multiple identical requests has the same effect as making a single request. The API supports idempotency for safely retrying requests without accidentally performing the same operation twice. This is useful when an API call is disrupted in transit and you do not receive a response. For example, if a request to create a charge does not respond due to a network connection error, you can retry the request with the same idempotency key to guarantee that no more than one charge is created.
• Safety: Action does not have any effect on the State. For example, Get action.

• APIs must be carefully crafted so they’re attractive to the intended consumer so it “sells.” (not literally)
