# Cancel an activation

DELETE https://{hostname}/edgeworkers/v1/ids/{edgeWorkerId}/activations/{activationId}

Cancel a pending activation. You can cancel any activation whose `status` is still `PENDING`. After that you need to wait for the activation to complete and then deactivate it. Once the deactivation is complete you can then delete the EdgeWorker version.
