# Learn about RFCs
<a name="ex-rfc-works"></a>

Requests for change, or RFCs, work in a two-fold manner. First, there are parameters required for the RFC itself. These are the options in the `CreateRfc` API. And second, there are parameters required for the action of the RFC (the execution parameters). To learn about the `CreateRfc` options, see the [CreateRfc](https://docs.aws.amazon.com/managedservices/latest/ApiReference-cm/API_CreateRfc.html) section of the *AMS API Reference*. These options typically appear in the **Additional configurations** area of the Create RFC pages.

You can create and submit an RFC with the `CreateRfc` API, `aws amscm create-rfc` CLI, or using the AMS console Create RFC pages. For a tutorial on creating an RFC, see [Create an RFC](ex-rfc-create-col.md).
