Synchronizer API V3: Post Payments, Read Claims, Treatment Plans

Published July 9, 2026 by Alamin Uddin, CEO & Co-Founder, NexHealth

Today, we're releasing a new stable version of the NexHealth Synchronizer API. It's the biggest release in the platform's history. Available to every developer now, and effective August 1 it becomes the official stable version of the Synchronizer API.

What's New in V3 (v20240412)

Financial Write-Back

Post payments and adjustments directly into the practice's system of record, using the practice's own payment and adjustment types. Revenue cycle, payments, and billing products can finally close the loop.

The Complete Financial Picture

Patient balances, guarantor balances, insurance balances, and fee schedules down to the procedure level. If it affects what a practice is owed, it's in the API.

Insurance Intelligence

Read claims and their statuses, coverage details, and eligibility data across all supported EHRs.

Clinical Data

Treatment plans and clinical notes are now accessible via the API, enabling clinical decision support and documentation tools.

27 New Developer Workflows

V3 adds 27 new end-to-end API workflows across all 15 supported practice management systems.

Scale

Synchronizer now connects over 10,000 practice locations. That's a larger developer ecosystem than the Open Dental, Henry Schein, Planet DDS, and Patterson developer programs combined.
