# Create VM Signal

`POST /azure/compute/vm/signal`

The VM signal API is used for notifying Spot about the VM state so that Spot can act accordingly. Supported signals are vmReady – Whenever this signal is sent, Spot will register the instance to the relevant Load Balancer and Application Gateway. vmReadyToShutdown – When this signal is received after a vm is detached; we will immediately terminate the vm. You must define the expected signals for your Elastigroup in the group configuration.
