This WHMCS module will allow you to integrate Square with WHMCS. By enabling the module, you will be able to select Square Gateway in WHMCS, and will need to enter your developer API credentials, which can be requested for free from https://squareup.com/us/en/developers
Upon purchase, you will receive the square gateway files. Simply put everything as required into the modules file, although square.tpl will go into your WHMCS template folder. You will be able to click Addon Modules and Enter your License Key. IF you do not enter your license key, the form will not show, as your license would not show valid.
Upon validation, and inputting your API credentials, you will be able to select your Square Store Location, and will be able to officially take payments through the gateway. There is a SANDBOX mode with SANDBOX Credentials, so you will be able to TEST the module before accepting official payments through square.
It is also important to note, that a legal WHMCS license is required. If you are found with an INVALID WHMCS license, we may suspend your license for the use of the gateway. An Installation Service is offered for purchase for assistance with installing the module!
