Refreshes an API authentication token using a valid refresh token.

Unique resource name: api_authentication.v1.refresh

This endpoint allows clients to obtain a new access token by providing a valid refresh token. The refresh token must be issued by the authentication service and must not be expired.

Authentication Process:

• The refresh-token header must contain a valid refresh token.
• If the refresh token is valid, a new access token is issued.
• If the refresh token is invalid or expired, a 401 Unauthorized response is returned.

Security Considerations:

• Refresh tokens should be stored securely and not shared.
