Batch delete patterns in Rest API - Cheat Sheet & Quick Revision

Recall & Review

What is a batch delete pattern in REST APIs?

A batch delete pattern allows clients to delete multiple resources in a single request, improving efficiency by reducing the number of calls to the server.

Name two common HTTP methods used for batch delete operations.

DELETE and POST are commonly used. DELETE is standard but sometimes POST is used with a payload listing items to delete when DELETE with a body is not supported.

Why might a REST API use POST instead of DELETE for batch deletes?

Because some servers or clients do not support sending a body with DELETE requests, POST is used to send a list of IDs to delete in the request body.

What is a common request body format for batch delete operations?

A JSON array or object listing the IDs or identifiers of the resources to delete, for example: {"ids": [1, 2, 3]}

beginner

What HTTP status code usually indicates a successful batch delete?

204 No Content indicates success with no response body. Sometimes 200 OK with details about deleted items is used.

Which HTTP method is standard for deleting a single resource in REST?

A GET

B DELETE

C POST

D PUT

DELETE is the standard HTTP method to remove a resource.

Why might POST be used for batch deletes instead of DELETE?

A Because POST is the only method supported by browsers

B Because POST is faster than DELETE

C Because POST can include a request body listing multiple items

D Because DELETE cannot delete resources

POST allows sending a request body with multiple IDs to delete, which DELETE sometimes does not support.

What is a typical response status code after a successful batch delete?

A 204 No Content

B 500 Internal Server Error

C 404 Not Found

D 301 Moved Permanently

204 No Content means the server successfully processed the request but returns no content.

Which of these is a common way to specify which items to delete in a batch delete request?

A Sending a JSON array of IDs in the request body

B Including IDs in the URL query string only

C Using HTTP headers to list IDs

D Sending IDs as cookies

A JSON array in the request body is a clear and common way to specify multiple IDs.

What is a benefit of batch delete patterns in REST APIs?

A Makes the API slower

B Prevents deletion of resources

C Increases server load unnecessarily

D Reduces the number of HTTP requests needed

Batch deletes reduce network overhead by combining multiple deletions into one request.

Explain how batch delete patterns improve REST API efficiency.
