[Solved] Identify the error in this HAL JSON snippet: { "_links": { "self": "/orders/123", "items": [{ "href": "/items/1" }, { "href": "/items/2" }] } } | Rest API

Rest API - HATEOAS and Linking

Identify the error in this HAL JSON snippet:

{
  "_links": {
    "self": "/orders/123",
    "items": [{ "href": "/items/1" }, { "href": "/items/2" }]
  }
}

AThe JSON is correct as is

B"items" should be a single object, not an array

C"self" link should be an object with an "href" property

D"_links" key should be "links" without underscore

Step-by-Step Solution

Solution:

Step 1: Check the structure of the "self" link
In HAL, each link must be an object with an href property. Here, "self" is a string, which is incorrect.
Step 2: Verify other parts
"items" is correctly an array of link objects. The _links key must have an underscore. So only "self" link is wrong.
Final Answer:
"self" link should be an object with an "href" property -> Option C
Quick Check:
HAL links = objects with href [OK]

Quick Trick: All HAL links must be objects with href keys [OK]
