California (CalEVV) EVV Vendor Solutions Specifications v2.8

This article will help you to: 

  • Understand the required elements for the EVV Vendor Solutions program. 
  • Understand the interface processes and requirements. 


This specification is intended to document the requirements for using the Sandata Real Time Interface (part of the Open EVV Series of Interface) for receiving information from 3rd party EVV Vendors into the Sandata Aggregator. This interface is also referred to as the EVV Vendor Solutions Data Interface. A Third Party EVV Data Collection System will build one data pipe to the Aggregator and send synchronous data ‘packages’ per defined provider agency.

This interface includes clients, employees, visits, and their associated calls as well as the ability to send data related to visit modifications.
