API key authentication in Rest API - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to add the API key to the request headers.

Rest API

headers = {"Authorization": "[1]"}

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

A"ApiKey 12345"

B"Key 12345"

C"Token 12345"

D"Bearer 12345"

💡 Hint

Common Mistakes

Using "Bearer" instead of "ApiKey" prefix.

Not including the API key in the header.

Using incorrect header names.

The API key is usually sent in the Authorization header with the prefix "ApiKey" followed by the key.

medium

Complete the code to send a GET request with the API key in the headers using Python requests.

Rest API

response = requests.get(url, headers=[1])

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

💡 Hint

Common Mistakes

Passing the API key in 'auth' or 'params' instead of 'headers'.

Not passing headers at all.

The API key should be sent in the headers parameter of the requests.get() function.

3fill in blank

hard

Fix the error in the code to correctly include the API key in the request headers.

Rest API

headers = {"Authorization": "ApiKey " + [1]
response = requests.get(url, headers=headers)

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

A"12345"

B12345

C'12345'

D"Bearer 12345"

💡 Hint

Common Mistakes

Not quoting the API key value causing syntax errors.

Using the wrong prefix like "Bearer".

The API key value must be a string inside quotes and combined with the prefix "ApiKey" in the header value.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that filters headers to only include the API key header.

Rest API

filtered_headers = {k: v for k, v in headers.items() if k [1] "Authorization" and v [2] "ApiKey 12345"}

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

B!=

C>

D<

💡 Hint

Common Mistakes

Using != which excludes the API key header.

Using comparison operators like > or < which don't make sense here.

We want to keep headers where the key equals "Authorization" and the value equals "ApiKey 12345".

5fill in blank

hard

Fill both blanks to build a dictionary comprehension that includes headers with keys starting with 'X-' and values containing 'token'.

Rest API

filtered = {k:v for k, v in headers.items() if k[1] "X-" and "token" [2] v}

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

A:

B.startswith(

Cin

D==

💡 Hint

Common Mistakes

Using '==' instead of ':' in dictionary comprehension.

Using '==' instead of 'in' for substring check.

Not using startswith() for prefix check.

The dictionary comprehension syntax uses ':' between key and value. The key check uses startswith(), and the value check uses 'in' to find substring.
