# Enables automatic scaling for a Pool.

`POST /pools/{poolId}/enableautoscale`

You cannot enable automatic scaling on a Pool if a resize operation is in progress on the Pool. If automatic scaling of the Pool is currently disabled, you must specify a valid autoscale formula as part of the request. If automatic scaling of the Pool is already enabled, you may specify a new autoscale formula and/or a new evaluation interval. You cannot call this API for the same Pool more than once every 30 seconds.
