POS API with javascript possible?

I am working on a web based POS system that is accessed on raspberry pi's. I have looked through the square docs and the only POS API seems to be for Android/iOS. Is there something I am missing? My front end is HTML/Javascript and the backend uses PHP. There are also a few small python programs running for example, to fill in text inputs like product weight with a USB connected scale.

I know square has the web form API, but that is not what I am looking for. The goal is to have cards scanned with a square card reader and then charge based on a given value. Thanks.

The docs say you can access their rest api via postman so you should be able to access it via an http client on your server docs.connect.squareup.com/api/connect/… - vbranden
@vbranden From what I've read, to charge a card you need to generate a nonce but you can only do that with SqPaymentForm which requires entering all of the credit card fields, # CVV, date, etc. Otherwise you need a customer_id which requires one of: given_name, family_name, company_name, email_address, phone_number. But I do not have any of these because customers here do not have an account. Can I just generate random nonsense for one of these fields? - Apickle
Not sure but in sasl a nonce can be any one time random string so I’d imagine you can generate your own nonce as long as it meets any requirements for length - vbranden
Unfortunately it looks like for this you need their nonce because it corresponds with the card you are charging and it expires after 24 hours. - Apickle

You will not be able to connect a Square card reader to your raspberry pi. You could let customers key in transactions with the e commerce APIs however.
