Definition
The practice of maintaining multiple versions of an API to allow gradual migration when breaking changes are introduced.
In Depth
API versioning strategies include URL versioning (/v1/users), header versioning, and query parameter versioning. Proper versioning allows API consumers to upgrade at their own pace without breaking existing integrations.
Example Usage
Releasing /api/v2/orders with a new response format while keeping /api/v1/orders running for existing integrations.
Business Context
API versioning prevents integration breakage and allows you to improve APIs without forcing all consumers to update simultaneously.
