National Immunization Information Platform Opens Reservation Surplus API
Five provinces pilot vaccine appointment surplus query interface; first integration with regional medical group apps, OAuth 2.1 security, commercial monetization prohibited.
The National Immunization Information Platform began gray-scale opening of vaccine appointment surplus query APIs in five provinces today, with first integration targets being regional medical group official apps.
API Design
Interface specifications:
- Endpoint:
GET /api/v1/vaccine/slots/{regionId} - Authentication: OAuth 2.1, requires medical institution qualification
- Returns: Vaccination site surplus, appointment slots, fastest available time
- Rate limit: Maximum 1000 calls per app per hour
Security Constraints
The platform has set strict restrictions on API usage:
- OAuth 2.1 authentication: Only registered medical institution apps can access
- Audit log retention: Callers must retain logs for over 90 days for regulatory inspection
- Commercial prohibition: Explicitly prohibits using surplus data for commercial ranking or scalping
- Data anonymization: Return data contains no personally identifiable information
First Pilot Provinces
- Beijing, Shanghai, Guangdong, Zhejiang, Jiangsu
Market Impact
Previously, vaccine appointments mainly relied on community health service center phone calls or on-site queuing. Non-transparent surplus information led to:
- Parents frequently calling to inquire
- Popular vaccines "hard to find"
- Off-peak hours ignored
With API opening, third-party apps can develop smart reminders, appointment scheduling, and other features to improve vaccination efficiency.
