An API (application programming interface) is the building blocks developers use to create software and applications. Think of it as the linking of information between one source and another and the automation of tasks between them. You can use FreshBooks' API to automate different parts of your FreshBooks account or to create integrations with your favourite apps.
If you are a developer/programmer interested in building an app with your account, FreshBooks' API makes it easy to create these apps through OAuth2 for authentication. For inspiration, check out our AppStore for our available apps anytime here.
