%% @doc Amazon Web Services Support App in Slack
%%
%% You can use the Amazon Web Services Support App in Slack API to manage
%% your support cases in Slack for your Amazon Web Services account.
%%
%% After you configure your Slack workspace and channel with the Amazon Web
%% Services Support App, you can perform the following tasks directly in your
%% Slack channel:
%%
%% <ul> <li> Create, search, update, and resolve your support cases
%%
%% </li> <li> Request service quota increases for your account
%%
%% </li> <li> Invite Amazon Web Services Support agents to your channel so
%% that you can chat directly about your support cases
%%
%% </li> </ul> For more information about how to perform these actions in
%% Slack, see the following documentation in the Amazon Web Services Support
%% User Guide:
%%
%% <ul> <li> Amazon Web Services Support App in Slack
%%
%% </li> <li> Joining a live chat session with Amazon Web Services Support
%%
%% </li> <li> Requesting service quota increases
%%
%% </li> <li> Amazon Web Services Support App commands in Slack
%%
%% </li> </ul> You can also use the Amazon Web Services Management Console
%% instead of the Amazon Web Services Support App API to manage your Slack
%% configurations. For more information, see Authorize a Slack workspace to
%% enable the Amazon Web Services Support App.
%%
%% You must have a Business or Enterprise Support plan to use the Amazon Web
%% Services Support App API.
%%
%% For more information about the Amazon Web Services Support App endpoints,
%% see the Amazon Web Services Support App in Slack endpoints in the Amazon
%% Web Services General Reference.

%% @doc Creates a Slack channel configuration for your Amazon Web Services
%% account.
%%
%% You can add up to 5 Slack workspaces for your account.
%%
%% You can add up to 20 Slack channels for your account.
%%
%% A Slack channel can have up to 100 Amazon Web Services accounts. This
%% means that only 100 accounts can add the same Slack channel to the Amazon
%% Web Services Support App. We recommend that you only add the accounts that
%% you need to manage support cases for your organization. This can reduce
%% the notifications about case updates that you receive in the Slack
%% channel.
%%
%% We recommend that you choose a private Slack channel so that only members
%% in that channel have read and write access to your support cases. Anyone
%% in your Slack channel can create, update, or resolve support cases for
%% your account. Users require an invitation to join private channels.

%% @doc Registers a Slack workspace for your Amazon Web Services account.
%%
%% To call this API, your account must be part of an organization in
%% Organizations.
%%
%% If you're the management account and you want to register Slack workspaces
%% for your organization, you must complete the following tasks:
%%
%% <ol> <li> Sign in to the Amazon Web Services Support Center and authorize
%% the Slack workspaces where you want your organization to have access to.
%% See Authorize a Slack workspace in the Amazon Web Services Support User
%% Guide.
%%
%% </li> <li> Call the `RegisterSlackWorkspaceForOrganization' API to
%% authorize each Slack workspace for the organization.
%%
%% </li> </ol> After the management account authorizes the Slack workspace,
%% member accounts can call this API to authorize the same Slack workspace
%% for their individual accounts. Member accounts don't need to authorize the
%% Slack workspace manually through the Amazon Web Services Support Center.
%%
%% To use the Amazon Web Services Support App, each account must then
%% complete the following tasks:
%%
%% <ul> <li> Create an Identity and Access Management (IAM) role with the
%% required permission. For more information, see Managing access to the
%% Amazon Web Services Support App.
%%
%% </li> <li> Configure a Slack channel to use the Amazon Web Services
%% Support App for support cases for that account. For more information, see
%% Configuring a Slack channel.
