Which HTTP method would you use to update a record through an API?

To update a record through an API, the HTTP method commonly used is PUT or PATCH. The choice between PUT and PATCH depends on the semantics of the update operation.

• PUT: Typically used to update a resource or create it if it doesn’t exist. When you use PUT to update a resource, you generally send the full representation of the resource in the request.

• PATCH: Used to apply partial modifications to a resource. It is often used when you want to update only specific fields of a resource, rather than sending the entire updated representation.

Which REST methods require an ID parameter?

• GET: Retrieve a resource.
• PUT: Update a resource.
• DELETE: Delete a resource.

What’s the relationship between REST and CRUD?

REST (Representational State Transfer) is an architectural style for designing networked applications, and CRUD (Create, Read, Update, Delete) operations align with the standard HTTP methods in a RESTful API.

If you had to describe the process of creating a RESTful API in 5 steps, what would they be?

• Define Resources and Endpoints:

  • Identify the entities/resources your API will expose.
  • Define unique URLs (endpoints) for each resource.

• Use HTTP Methods for Operations:

  • Map CRUD operations to appropriate HTTP methods.
  • POST for Create.
  • GET for Read.
  • PUT or PATCH for Update.
  • DELETE for Delete.

• Design Data Formats:

  • Choose data formats for requests and responses (e.g., JSON or XML).
  • Define clear and consistent data structures.

• Implement Server-Side Logic:

  • Develop the server-side logic to handle requests.
  • Use frameworks or libraries that support routing, request handling, and database interactions.

• Handle Errors and Security:

  • Implement error handling mechanisms, providing meaningful error responses.
  • Address security concerns (authentication, authorization, and secure communication).
