You send a POST request to `https://api.example.com/orders` with a JSON body containing order details. What is the expected outcome?

The server creates a new order and returns its details.

The server deletes the order with the specified ID.

The server returns the existing order with ID 1.

The server updates the order with the specified ID.

What is the primary purpose of authentication in a REST API?

To verify the identity of the client making the request.

To encrypt the request and response data.

To compress the data being sent.

To log all requests for auditing purposes.

Which authentication mechanism is commonly used in REST APIs where the client sends a secret key in the request header?

OAuth 2.0 client credentials flow

Basic authentication with username and password in the URL

A security-conscious organization requires that all API interactions use OAuth 2.0 with short-lived access tokens. An automation script needs to create a new project via POST /projects. The script has already obtained an access token. How should the script include the token in the request?

In the URL as a query parameter

In a custom header named 'X-API-Key'

In the Authorization header as 'Bearer '

In the request body as a JSON field
