Mastering API Consistency: Kroger's Journey and Tools
summary
Kroger describes concrete moves: a central developer Marketplace and API catalog that ingest OpenAPI specs via CI/CD, an OAuth2 standard for auth, a live linter service (iterated to v4) that enforces the style guide, an external-facing gateway plus app registration, and an integration layer that shields internal teams from partner variability. Those pieces reduce duplicate endpoints, speed left-shifted testing, and make APIs reusable across 20 banner brands and 2,500 stores; next goals are more self‑service and AI/ML-assisted automation.
