# Authentication

Version 1 of the HealthSherpa Partner API uses API key authentication to secure all requests.

Each partner organization is provided with an unique API key that must be included in all API requests. These API keys are tied to your agency.

Additionally, each endpoint requires an `agent_email` parameter which is used to authenticate individual downline agents within your agency.
