  title: Prismatic Rotate Refresh Token
  summary: Refresh an access token, use it, then revoke the old refresh token.
  description: >-
    Implements a secure credential rotation pattern. The flow exchanges the
    current refresh token for a fresh access token, immediately exercises that
    access token against the documented listCustomers GraphQL query to confirm it
    works, and then revokes the original refresh token so it can no longer be used
    to mint new access tokens. Note: Prismatic exposes dedicated auth endpoints
    for refresh and revoke, while the data read is a request body sent through the
    single GraphQL-over-HTTP executeGraphQLQuery endpoint.
