💡 Hint

Common Mistakes

Using the data variable name instead of a URL string.

Omitting quotes around the URL string.

The self link should point to the current resource URL, which is "/api/users/123" here.

💡 Hint

Common Mistakes

Using the current page number instead of the next page.

Using an invalid page number like 0.

The 'next' link should point to the next page, which is page 2 in this example.

💡 Hint

Common Mistakes

Using variable names instead of URL strings.

Missing the leading slash in the URL.

The 'related' link must be a URL string starting with a slash to be a valid hypermedia link.

Rest API

💡 Hint

Common Mistakes

Using the wrong variable name for data.

Setting the 'next' link to an incorrect page.

The data key should hold the variable items, and the 'next' link should point to page 2.

5fill in blank

hard

Fill all three blanks to build a hypermedia response with filtered data and links.

Rest API

filtered = [item for item in all_items if item['type'] == [1]]
response = {"data": filtered, "_links": {"self": [2], "related": [3]

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

A"book"

B"/api/items?type=book"

C"/api/items/related"

Attempts:

3 left

💡 Hint

Common Mistakes

Using variable names instead of string literals for filtering.

Omitting quotes around URL strings.

The filter uses the string "book". The 'self' link points to the filtered URL, and 'related' points to a related resource URL.
