HTTPRequest class doesn't exist in PHP 7+ (replacement in documentation)

[igvinc]

Problem: 

HTTPRequest class doesn't exist in PHP 7+

The HTTP extension is a PECL package that needs to be installed separately.

This is 'difficult to impossible' to accomplish on shared hosting platforms

$request = new HttpRequest();

However, the https://v3.developer.constantcontact.com/ guide consistently uses HttpRequest() as the example.

Requested Solution:

Test, confirm and show real world working examples using cURL instead.

Your feedback and experience with this request is essential to improving our product, so thank you for reaching out to us regarding this matter.

In the meantime, here are the example calls that are currently available for V3:
