%% @doc Welcome to the Amazon AppFlow API reference.
%%
%% This guide is for developers who need detailed information about the
%% Amazon AppFlow API operations, data types, and errors.
%%
%% Amazon AppFlow is a fully managed integration service that enables you to
%% securely transfer data between software as a service (SaaS) applications
%% like Salesforce, Marketo, Slack, and ServiceNow, and Amazon Web Services
%% like Amazon S3 and Amazon Redshift.
%%
%% Use the following links to get started on the Amazon AppFlow API:
%%
%% <ul> <li> Actions: An alphabetical list of all Amazon AppFlow API
%% operations.
%%
%% </li> <li> Data types: An alphabetical list of all Amazon AppFlow data
%% types.
%%
%% </li> <li> Common parameters: Parameters that all Query operations can
%% use.
%%
%% </li> <li> Common errors: Client and server errors that all operations can
%% return.
%%
%% </li> </ul> If you're new to Amazon AppFlow, we recommend that you review
%% the Amazon AppFlow User Guide.
%%
%% Amazon AppFlow API users can use vendor-specific mechanisms for OAuth, and
%% include applicable OAuth attributes (such as `auth-code' and
%% `redirecturi') with the connector-specific `ConnectorProfileProperties'
%% when creating a new connector profile using Amazon AppFlow API operations.
%% For example, Salesforce users can refer to the Authorize Apps with OAuth
%% documentation.
