Yep. Want to accept onchain bitcoin? When a customer wants to pay, generate a fresh address. Store that address in a dab associated with the customer id. When they come for the service, see if that address has received payment. Easy peasy. You can run your own node and do this all yourself, or you can use services that run the software for you and work on callbacks or api calls.

Want to accept lightning (bitcoin over a low cost and high speed payment network)? It’s an api call to generate an invoice and another api call to see if that invoice has been paid. Again you can run everything yourself or use a managed service. Bitcoin make programmatic payment processing SO MUCH EASIER than traditional payment rails.
