title: providing PayPal payments functionality to SaaS customers
body: <p>I am developing a system that provides event signup/registration services. Event hosts should be able to offer online payment options to their customers via this system.</p>
  
  <p>I need a scenario when event owner (assuming he/she already has proper PayPal Business account) configures the minimal amount of information in the system (like merchant ID) and then he's able to receive online payments without having to dive into technical details of the integration.</p>
  
  <p>I have started with JavaScript button solution, but it turns out that it's not very customizable (for example I cannot change button title from 'Buy now' to 'Pay now').</p>
  
  <p>Then I have spent some time researching Button Manager API, but it seems to be over-complicated to accomplish the task of just changing the button title.</p>
  
  <p>Could somebody point me in a right direction?</p>
