# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.continuousauth.dev/usage/responders.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
