Redeem a handoff token for a shopper session
Step two of the handoff. Consumes the opaque token from the exchange operation and returns the member’s shopper session in the X-Customer-Token response header. Single use: a token is destroyed on redemption, and one issued for a different member or under a different company’s credential is rejected. The path member is part of the binding, so the session returned is always the one this URL names.
