# CancelCertificateTransfer
<a name="API_CancelCertificateTransfer"></a>

Cancels a pending transfer for the specified certificate.

 **Note** Only the transfer source account can use this operation to cancel a transfer. (Transfer destinations can use [RejectCertificateTransfer](API_RejectCertificateTransfer.md) instead.) After transfer, AWS IoT returns the certificate to the source account in the INACTIVE state. After the destination account has accepted the transfer, the transfer cannot be cancelled.

After a certificate transfer is cancelled, the status of the certificate changes from PENDING\$1TRANSFER to INACTIVE.

Requires permission to access the [CancelCertificateTransfer](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions) action.
