# What is it? **The Dataloy REST API** allows for the retrieval, updating and entry of all data in Dataloy VMS. As the Dataloy API is based on REST principles it is easy to write and simple to use when testing applications. A typical company uses many applications, of which many or most are not designed to work with one another. Integrating separate, but related, applications help organizations achieve greater levels of operational consistency, efficiency and quality. Integration can be considered if a system generates/consumes data relevant to Dataloy VMS and/or can share data with the VMS. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
