Web services are application programming interfaces (APIs) exposing a platform features across the web, for integration by systems and applications rather than normal users. For instance a platform could feature a way to look up average rental prices by zip code, which an external application could integrate to allow its users to perform this look up. Web services are integral to the architecture of Internet applications across the world, enabling systems, apps and websites to leverage external data sources or facilities to deliver their own services.

Any designer or developer for online applications will require knowledge of integrating web services, and will have experience in the use of such APIs in their code, typically using standard libraries or software development kits (SDK) provided by the party hosting the web services. Businesses can quickly leverage powerful functionality by the integration of existing web services, and may look to offer web services of their own to be integrated by other parties; for either purpose development skills for web services are invaluable.
