What are APIs?

Imagine you could access your real-time banking activity without exporting data, uploading files, or signing in to Online Banking for Business – BMO APIs let you do that and more.

APIs (Application Programming Interfaces) allow systems and apps to share information with each other. Whether you want to see your latest account balances in your accounting software or build an app to analyze your cash flow, our intelligent APIs make it easy to connect to your Online Banking for Business accounts. And because they use BMO’s bank-level security, you can trust that your data is safe.
