@spec create(Sumup.Config.t(), String.t(), keyword() | map()) ::
  {:ok, Sumup.Member.t()} | {:error, Sumup.Error.t()}

Creates a member under merchant_code.

• :email (String.t/0) - Required.

• :roles (list of String.t/0) - Required. Role ids to assign on creation.

• :is_managed_user (boolean/0) - Create a SumUp-managed (virtual) user rather than inviting a real one.

• :password (String.t/0) - Required when is_managed_user: true.

• :nickname (String.t/0)

• :metadata (map/0) - Free-form metadata you control.

• :attributes (map/0) - Free-form attributes you control.

@spec delete(Sumup.Config.t(), String.t(), String.t()) ::
  :ok | {:error, Sumup.Error.t()}

Removes a member from a merchant.

@spec get(Sumup.Config.t(), String.t(), String.t()) ::
  {:ok, Sumup.Member.t()} | {:error, Sumup.Error.t()}

Retrieves a single member.

@spec list(Sumup.Config.t(), String.t(), keyword()) ::
  {:ok, map()} | {:error, Sumup.Error.t()}

Lists a single page of members.

• :offset (non_neg_integer/0) - Page offset. The default value is 0.

• :limit (pos_integer/0) - Page size (max 25). The default value is 10.

• :scroll (boolean/0) - Use scroll-based pagination instead of offset/limit.

• :email (String.t/0) - Filter/search by email (substring).

• :user_id (String.t/0) - Filter by the underlying user id (maps to user.id).

• :status

• :roles (list of String.t/0) - Filter to one or more role ids.

@spec list_all(Sumup.Config.t(), String.t(), pos_integer()) :: Enumerable.t()

Lazily streams every member, paging by offset/limit. See Sumup.Pagination.

@spec update(Sumup.Config.t(), String.t(), String.t(), keyword() | map()) ::
  {:ok, Sumup.Member.t()} | {:error, Sumup.Error.t()}

Replaces a member's roles/metadata/attributes/managed-user credentials.
