Hi Ashish,
iHealth is not in Terra's supported integrations list. Terra's Health & Fitness API covers 500+ data sources across bloods, wearables, fitness trackers, nutrition apps, and medical devices, but iHealth is not among them yet!
For connected health monitor data like blood pressure or weight readings, Omron, Withings and Tenovi are both available in the medical devices category today. You can browse the full list here: https://docs.tryterra.co/reference/health-and-fitness-api/supported-integrations
If iHealth support matters for your use case, you can submit an integration request to the Terra team at https://tryterra.co/enterprise/contact.
