Frequently Asked Questions

How can I integrate payments into my custom Point of Sale (POS) app? Expand

Software vendors (ISVs) looking to add payments to their product have countless software and hardware options to choose from. Most POS payment solutions use semi-integrated payment architecture because it keeps sensitive credit card data out of the ISV's and merchant's systems. See American PaySave’s semi-integrated APIs here for more information.

What are American PaySave’s no-code and low-code integration options? Expand

We have payment plugins like WooCommerce and BigCommerce as well as a Hosted Checkout form. View American PaySave’s Low-code and no-code ecommerce options here.

How do payment request APIs work? Expand

Payment APIs are similar to other APIs requests, but the requests travel through specific financial institutions for a successful response. When a payment request object is sent, the data is sent through an API gateway, on to the processor, to one of the major card networks, and finally, the issuing bank. Read this American PaySave Developers blog article for more information on Payment Request APIs.
