Healthcare APIs & integration
The integration layer is where most healthcare programmes quietly fail. It is worth designing properly.
Overview
The layer everything else depends on
The integration layer is where most healthcare programmes quietly fail. It is worth designing properly.

- Data governance
- Monitoring & alerting
- Incident response
- Secure integration patterns
On standards
Architectures are designed to support the requirements of frameworks such as DPDP, and — where applicable — HIPAA, GDPR, ISO 27001 and SOC 2. Design alignment is not certification and none is claimed here.
