Urgent: send custom parameters to dynamic transfer call vapi
If I use parameters that I need to receive at my webhook when creating my dynamicTransfer function, the “transfer-destination-request” is not executed.

If I don't use parameters and leave everything blank, the
“transfer-destination-request” is executed, but I can't receive the variables I need.
