Common questions about the Wise API.

An API allows different platforms and tools communicate with one another and share important stuff. For example, ever wonder how Google docs can appear on your Slack feed? Well – Google uses the Slack API to keep all your documents in one place. Another example is having the option to create a profile with your Facebook account. It really speeds up getting start with a new food delivery app, right?

For us, we know there are ways to make Wise work even better for you – but it would take us a while to build it all. Giving you access to our open API is like us opening the door to the inside of Wise – come on in and take what you need for your business.

An API token is a unique identifier that an app or website can use to access to the API of other companies, like Wise. You can generate an API token with Wise from our sandbox environment or your business account page. Your developers would need it to build the integration.
