# RejectRfc


Marks the specified RFC as rejected. The alternate operation to `ApproveRfc`.

An RFC with a CT of "Execution mode: Manual" requires approval; rarely it requires customer response, either approval or rejection. If your response is explicitly required, the `Approval Status: CustomerApproval Pending` RFC status is in the RFC execution output, but you receive no other notice. You must explicitly reject or approve the RFC by running this operation or the ApproveRfc operation.
