Square Payment Module for Zen Cart [Support Thread]

[DrByte]

I am so confused why something that is so straight forward looking doesn't working.

Agreed. But let's collaborate to find a solution.

version 0.97 Square Payment not working.
I have my Application ID & Application Secret filled from my square APP like instructions call for. Location ID is blank and wont show my store numbers.
I get (Access Token needed) in red.
I don't have any url redirects in turned on in my htaccess

This is a sub domain with its own url, that shouldn't affect anything?

A subdomain technically shouldn't be a problem, as long as the complete URL is set in your Square OAuth settings.

When I run my square_handler.php I get a HTTP ERROR 417

How EXACTLY are you getting that?
... cuz in the code, unless altered, a 417 is only sent if running it from a command-line, not a browser
... further, the text string "HTTP ERROR 417" is never sent in human-visible text
That said, a 417 response means that either the module is Disabled in your admin (status set to 'false'), or the token is not set/valid.

Next, what exactly happens when you click the green button in your Admin to get an access token? Step by step.
