I want to automate certain payments through scripts. mainly for personal reasons. what is the best way to automate ?<p>so lets say i want to send some money to some number, i can type in terminal<p>`upi send 9954312345 5000`<p>it should send without any password.<p>mainly looking for information on what API providers are there, is it only banking apps that can do this? can we have sandboxed version so it works for 1 developer or 1 account.
