API Standardization – Two Approaches
Industry Standard API Provider Proprietary API
“As industry API provider, I want to
design my own API specifications
following industry agreed best
practices, and collaborate with IATA
team to certify my API.”
“Under industry governance, I want to
collaborate with other airlines and
partners to design a common industry
standard API specification.”

9.
IATA’s Open Air Program
addresses those challenges by building an Open API
ecosystem through industry standards and services
under industry governance

Swagger is the OpenAPI Specification
A Single Source of Truth for API Development
Single source of truth for
• Design
• Development
• Testing
• Operations
• Documentation
Provide structure at scale
• Team / Organization arrangement
• Manage permissions and sharing across teams
• Integrate w/SSO services
• Robust version support
Create design-driven workflows + processes
• Built-in commenting and feedback loop

• Hand off designs through SDLC stages
• Share common assets across teams and projects

14.
Enforce design rules from the top down
• Define design rules to be used across an organization
• Resolve quality issues before reaching development
• Give real-time feedback as definitions are written
Create a library of reusable assets
• Store pre-approved definitions
• Teams create references
• Updates are pushed down to other services
Built on the industry standard for API definitions
• OpenAPI Initiative is a collaboration of leaders in the industry
• Industry wide support for OAS
• Evolving standard is growing and adapting to the needs of API
providers and consumers Asset Library

Open Air adoption so far
12 Airlines and 1 start up have already certified
and published Open Air compliant APIs:
IATA’s API certification program validates the compliance of APIs
against Best Practices described in the Open Air API Certification
Compliance Checklist.
Exposure of APIs to
potential consumers
and possibility to gain
new business partners
Certification is free
of charge
