Predefined Format for single call leg flow :

{	
    "callDetails": [
		{
			"calleeNumber": "Phone number of the callee",
			"connectTime": "Timestamp of call when started",
			"didNumber": "DID used in call",
			"duration": "Total Call duration in seconds",
			"endTime": "Timestamp of call when ended",
			"hangupCause": "Hangup cause code of the call",
			"incoming": True if the call was incoming false otherwise,
			"startTime": "Timestamp of call when started"
		}
	],
	"keys": [
		{
			"name": "$flow.key.variable1",
			"value": "value of variable"
		},
		{
			"name": "$flow.key.variable2",
			"value": "value of variable"
		} // This will be repeated for all the variables passed during the call
		
	],
	"phonon-uuid": "Phonon uuid of the call",
	"recordingUrls": [
		{
			"recordedFileName": "file name of the recording",
			"recordedFilePublicPath": "URL of the recording, where it is stored"
  }
  ]
  }

Outcome : Everytime the flow is executed, all the flow details (as mentioned in the format) will be send Predefined Format for flow with two call legs, i.e customer and agent call legs in outbound multicast flow :
