To create or update data via an API, which HTTP method is commonly used?

• A. PUT
• B. POST
• C. GET
• D. PATCH

Answer: (B)

HTTP methods define what action you want to perform on a resource. POST is used to submit data to a server for processing, and it’s commonly used to create a new resource under a collection. Because POST is not idempotent, sending the same payload twice can result in multiple resources being created, which fits typical create workflows. For updates, other methods are used: PUT replaces a resource entirely, and PATCH applies a partial update; GET simply retrieves data. So when the goal is to send data to the API to have it created or changed, POST is the standard choice, which is why it’s the best answer here.
