VivaLNK (Vivalink) is a connected-health company providing medical-grade wearable biosensors and a Biometrics Data Platform for remote patient monitoring (RPM), hospital-at-home, and decentralized clinical trials. Its wearable sensors capture ECG, heart rate, heart rate variability, respiratory rate, RR interval, body/axillary temperature, SpO2, blood pressure, and three-axis accelerometer data. Mobile edge clients read the sensors over Bluetooth Low Energy (BLE) and deliver data to the cloud over RESTful HTTPS services (Amazon API Gateway plus Amazon Kinesis for near-real-time ingestion). The platform exposes machine-to-machine (M2M) cloud web-service APIs, webhook push, FHIR-based integration, and bulk data-file downloads for EHR, CTMS, and clinical-application integration. The developer surface is delivered through VivaLNK's SDK and Developer Program and is partner-gated; the full API reference is provided under license rather than published openly, so the endpoints described here are modeled from VivaLNK's documented platform capabilities.
