  MX provides test institutions in the integration environment rather than card
  fixtures (it is a data aggregator, not a card acquirer). Credentials come from
  the Client Dashboard (dashboard.mx.com): client_id as username, api_key as
  password via HTTP Basic. The OpenAPI declares two servers — int-api.mx.com
  (integration/test) and api.mx.com (production).
