Can I integrate actual payment gateways with a free Blogspot shop template, and if so, how?

Blogspot does not have native integrated payment gateways. However, you can integrate payment functionality by linking 'Buy Now' buttons on your product pages to external services. This typically involves using PayPal 'Buy Now' buttons, Gumroad links, or other third-party payment links generated by services that handle transactions. Customers are redirected to these secure external platforms to complete their purchase, and you manage orders manually.
