Vital Link API covers only cloud-based providers.Your mobile app has to manage connections with SDK-based providers — such as Apple HealthKit and Android Health Connect — through the Vital Mobile Health SDK, separately from Vital Link.
The Vital Link flow starts when a user wants to connect a wearable device with Vital. An overview of the process can be found below.
