# Responders

In CFA when we refer to a `Responder` we are referring to the part of the CFA process that interacts with the human to ask for an OTP, this is typically a chat integration like Slack.  It is the service that will actually be "responding" to the OTP request.

Once you added your repository as a project in CFA you should be able to choose from any of our supported Responders to configure.  For more information on each Responder and how to configure them please check the individual Responder pages.
