module: acme_account_info
author: "Felix Fontein (@felixfontein)"
short_description: Retrieves information on ACME accounts
description:
  - "Allows to retrieve information on accounts a CA supporting the
     L(ACME protocol,https://tools.ietf.org/html/rfc8555),
     such as L(Let's Encrypt,https://letsencrypt.org/)."
  - "This module only works with the ACME v2 protocol."
notes:
  - "The M(community.crypto.acme_account) module allows to modify, create and delete ACME
     accounts."
  - "This module was called C(acme_account_facts) before Ansible 2.8. The usage
     did not change."

  retrieve_orders:
    description:
      - "Whether to retrieve the list of order URLs or order objects, if provided
         by the ACME server."
      - "A value of V(ignore) will not fetch the list of orders."
      - "If the value is not V(ignore) and the ACME server supports orders, the RV(order_uris)
         return value is always populated. The RV(orders) return value is only returned
         if this option is set to V(object_list)."
      - "Currently, Let's Encrypt does not return orders, so the RV(orders) result
         will always be empty."
