NexHealth
NexHealth is a universal, real-time API for healthcare that lets developers read from and write to dozens of electronic health record (EHR) and practice management systems through a single standardized interface. The NexHealth Synchronizer API covers patients, providers, locations, scheduling and available slots, appointments, working hours, clinical notes, treatment plans, documents, insurance (plans, coverages, claims, balances), and practice financials (charges, payments, adjustments, fee schedules), with signed webhooks for real-time events. It is used across dental and medical practices and by health-tech companies building scheduling, billing, and patient-engagement products.
NexHealth publishes 33 APIs on the APIs.io network, including Adjustment Types API, Adjustments API, Appointment Types API, and 30 more. Tagged areas include Company, Healthcare, EHR, Practice Management, and Scheduling.
The NexHealth catalog on APIs.io includes 1 event-driven AsyncAPI specification.
NexHealth’s developer surface includes authentication, changelog, sandbox, documentation, API reference, getting-started guide, support, and 27 more developer resources.
