HHAeXchange is a homecare management platform providing scheduling, Electronic Visit Verification (EVV), Medicaid billing, and caregiver management for home health agencies and payers. The platform exposes RESTful HTTPS APIs enabling third-party EVV systems to integrate with state Medicaid programs.
The HHAeXchange EVV API allows third-party EVV vendors and aggregators to submit caregiver records and visit data for state Medicaid compliance. The API uses OAuth 2.0 (client credentials flow) for authentication and returns JSON responses.
