A webservice is defined by the W3C as "a software system designed to support interoperable machine-to-machine interaction over a network."
Put simply, The LabelEd webservice programming interface (API) gives third party developers the ability to write custom applications which can make use of, and/or update, the data in your LabelEd system.
For more detailed information on the LabelEd public APIs please see the developer documentation or contact us with any questions.
