We want to transfer our credit card processing from an older system to the Square API ([url removed, login to view])
We would pass credit card number, expiration date, CID, billing address to your php code that would interact with Square's API to process the payment and return "accepted" or "declined".
The Square API docs mention use of Composer to install components, but we are on a shared hosting system that does not provide this privilege, so you would have to figure out how to alternatively install the required Square libraries.
Should be a plain-vanilla PHP script.
I'm PHP programmer. I didn't work with Square, but I worked with some other payments APIs. Square has documentation, examples, sandbox for testing. I'm sure that I will not have any difficulties with your project.
