# Update a call Update an active call resource. You can use this request to do additional actions: * [You can use this request to hangup the call by setting status to `completed`](#user-content-fn-1)[^1] * It can also be used to update the `callFlow` of the call. Commands of the new `callFlow` will be executed after the Patch. ### CallFlowCommand Check bellow the available commands when initiating an outbound call. In order to assess the options of each command, you may explore each command section. ``` type: string enum: - answer - hangup - playback - say - gather - record - bridge - pause - ringing ``` ##
