## API Versioning

The HealthSherpa Medicare Partner API currently has two versions, `v1` which authenticates with **API keys** and `v2` which authenticates via **OAuth**.

In addition, `v2` has support for passing **provider**, **drug**, and **pharmacy** data from your CRM to HealthSherpa for Medicare if you can guarantee data with Connecture IDs.
