Fallback values in flow (webhook) template

[Ted_Steen]

I’m passing some arguments to a webhook flow ({{$trigger.payload.my_field}}) but if it is undefined I want it to default to an empty string. Can’t find any documentation about how to achieve that, can someone point me in the right direction?

Hello,

You can use script to transform the payload and define a empty string.
