  description: The iLab API enables customers to seamlessly integrate outside applications with iLab's billing and reporting modules. It leverages a RESTful application architecture with HATEOAS (Hypermedia as the Engine of Application State) and OAuth2 for secure access. The API supports integrations with institutional financial systems such as SAP, Oracle/PeopleSoft, Lawson, and Banner, as well as identity management systems and LIMS.
