An API is an Application Programming Interface. It’s a connection between computers or between computer programs; a type of software interface, offering a service to other pieces of software. In this case, between the OS Data Hub, and your servers.
You can use APIs on your website or apps, to create maps for customer engagement. It’s very likely that you’ve already used an OS API elsewhere, and not noticed. A very basic example would be an interactive map on an About Us page, to help you find a physical location like a shop or head office. They can help customers solve queries, with potential to reduce customer contact calls.
OS APIs provide direct access to our detailed, accurate, trusted data, with a variety of functionality options. The data is updated regularly so you always have the latest view.
