Rest API - HATEOAS and Linking

ALink: <https://api.example.com/items?page=4>; rel="next", <https://api.example.com/items?page=6>; rel="prev"

BLink: <https://api.example.com/items?page=6>; rel="next", <https://api.example.com/items?page=4>; rel="prev"

CLink: <https://api.example.com/items?page=5>; rel="next", <https://api.example.com/items?page=5>; rel="prev"

DLink: <https://api.example.com/items?page=7>; rel="next", <https://api.example.com/items?page=3>; rel="prev"

Step-by-Step Solution

Solution:

Step 1: Calculate next and previous pages for page 5
Next page after 5 is 6, previous page before 5 is 4.
Step 2: Match correct URLs with rel attributes
Link: ; rel="next", ; rel="prev" correctly assigns page=6 to rel="next" and page=4 to rel="prev".
Final Answer:
Link: <https://api.example.com/items?page=6>; rel="next", <https://api.example.com/items?page=4>; rel="prev" -> Option B
Quick Check:
Page 5 next=6, prev=4 [OK]

Quick Trick: Next page = current +1, prev page = current -1 in Link header [OK]

Common Mistakes:

Swapping next and prev URLs
Using current page number for both next and prev
Incorrect page numbers outside valid range
