Introduction

Edvak EHR’s API allows apps to securely access your health records in a standardized format called CCDA (Consolidated Clinical Document Architecture). This is a digital summary of your medical history that can include:
Medications
Allergies
Diagnoses
Lab results
Immunizations
Visit summaries
This information can be shared with apps — only with your permission — to help you manage your health better.
The CCDA data provided through this API conforms to the G9 certification standard for electronic health information access.

Security & Standards#

The Edvak EHR API follows:
CCDA (HL7) structure for patient documents.
OAuth 2.0 Bearer Token for secure app-level and user-level authorization.
HTTPS transport to encrypt all API requests and responses.

Why Use This?#

This lets you:
View your health history through apps
Share your medical info with new doctors or caregivers
Keep a personal copy of your health records
All access is protected using OAuth2 — meaning only you or apps you trust can view the data.

What Format Is the Data In?#

The data is provided in CCDA format, used widely across healthcare systems. It’s structured and app-friendly, making it easy to display and understand your information.

Example CCDA Document Types#

Continuity of Care Document (CCD)
Discharge Summary
Referral Note
Consultation Note
Progress Note
These documents follow the CDA R2 standard and include a header (with metadata and patient info) and a body (with clinical sections).

How It Works#

1.
An app requests access to your records
2.
You log in and approve access
3.
The app retrieves your CCDA summary securely using a token
