What is an API key?

API stands for Application Programming Interface - it's the technology that lets two systems, like IRIS and Allica Online Banking, exchange information with each other.

An API key is like a secure password for that connection. It lets IRIS and Allica Online Banking talk to each other safely, without you having to log in each time. It only allows the specific connection it's set up for, so it's safer than sharing your regular banking login.
