💡 Hint

Common Mistakes

💡 Hint

Common Mistakes

Using 200 instead of 201 for creation.

Confusing 404 (Not Found) with success codes.

Status code 201 means 'Created', indicating the resource was successfully created.

hard

Fix the error in the REST API endpoint path to follow best practices for resource naming.

HLD

The incorrect endpoint path is: '/getUserDetails/[1]'. Correct it to a RESTful style.

Drag options to blanks, or click blank then click option'

A/getUserDetails/{{BLANK_1}}

B/users/{{BLANK_1}}

C/user-details/{{BLANK_1}}

D/userDetails/get/{{BLANK_1}}

💡 Hint

Common Mistakes

Including verbs like 'get' in the endpoint path.

Using singular nouns inconsistently.

RESTful APIs use plural nouns for resource names, so '/users/{id}' is correct.

4fill in blank

hard

Fill both blanks to complete the REST API design for updating a resource using the correct HTTP method and status code.

HLD

To update a resource, the client sends a [1] request, and the server responds with status code [2] if successful.

Drag options to blanks, or click blank then click option'

D204

💡 Hint

Common Mistakes

Using PATCH instead of PUT for full updates.

Using 204 when content is expected in response.

PUT is used to update a resource fully, and 200 means the update was successful with content returned.

5fill in blank

hard

Fill all three blanks to complete the REST API design snippet for deleting a resource, including HTTP method, endpoint path, and expected status code.

HLD

The client sends a [1] request to '[2]/[3]' to delete a resource, and the server responds with status code 204.

Drag options to blanks, or click blank then click option'

ADELETE

Busers

C123

DGET

Attempts:

3 left

💡 Hint

Common Mistakes

Using GET instead of DELETE to remove resources.

Omitting the resource ID in the path.

DELETE method is used to remove a resource at '/users/123'. Status 204 means success with no content returned.
