There are three different ways of transferring data from OpenApply.
1. We support direct integrations with ManageBac, iSAMS and PowerSchool
3. For schools who would like to build their own custom integrations, we also provide a comprehensive Public API. Further details on our API can be accessed in your OpenApply account via Settings > Integrations > Public API > API Documentation
Our Public API should be implemented in a RESTful style using JSON over HTTP. We use GET, POST and PUT. We have further information on enabling the Public API and generating the API key here
