## Request Parameters
<a name="API_UpdateRfc_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [Description](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-Description"></a>
The new description of the RFC.  
Type: String  
Required: No

 ** [ExecutionParameters](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-ExecutionParameters"></a>
The new parameters that are required to execute the RFC, submitted in JSON format.  
Type: String  
Required: No

 ** [ExpectedOutcome](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-ExpectedOutcome"></a>
A new description of the effects of the change.  
Type: String  
Required: No

 ** [ImplementationPlan](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-ImplementationPlan"></a>
The new actions or steps required to implement the change (for change types that are not automated).  
Type: String  
Required: No

 ** [Notification](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-Notification"></a>
Notice that an RFC has been updated.  
Type: [RfcNotification](API_RfcNotification.md) object  
Required: No

 ** [RequestedEndTime](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-RequestedEndTime"></a>
The new end of the change window, expressed in ISO 8601 format. The default format is the *basic* format (`YYYYMMDDThhmmssZ`). For example, 2017/02/27 at 2:30 PM would be 20170227T143000Z. An RFC does not fail if the requested end time is exceeded.  
Type: String  
Required: No

 ** [RequestedStartTime](#API_UpdateRfc_RequestSyntax) **   <a name="amscm-UpdateRfc-request-RequestedStartTime"></a>
The new start of the change window, expressed in ISO 8601 format. The default format is the *basic* format (`YYYYMMDDThhmmssZ`). For example, 2017/02/27 at 2:10 PM would be 20170227T141000Z. For best results, set the requested start time to at least 10 minutes past the time that you expect to submit the RFC. For review required change types, you must set a start time that's at least 24 hours after you expect to submit the RFC. Alternatively, you can use the ASAP option, which causes the RFC to execute as soon as it's approved. To use the ASAP option, don't specify a start time. If the RFC doesn't pass syntax or other checks before the requested start time (if set), then the RFC is canceled.  
Type: String  
Required: No
