Is it possible to charge taxes using the square POS API? I want to start a POS transaction from my APP and send a tax percentage to be added with the ChargeRequest.Builder.
Example: Customer charges $1.00 using my app and it redirects the customer to the square register app. I want to send a percentage tax along with the ChargeRequest. Is it possible?
No, you cannot pass a tax with your transaction at this time, but you can set up taxes in the Point of Sale app and and transactions that you create will use that tax. See https://squareup.com/help/us/en/article/5061-modify-your-tax-settings
