Using logic to invite users through webhook

Hey guys! Has anyone had success automatically inviting users to set up a user account from an incoming webhook? I can’t work out how to format the webhook data to get logic to recognise the incoming data as an email address (and therefore it won’t let me invite a new user). I’ve used Zapier to set up the Webhook if that helps!

For this it’s easier to use an external automation platform like Make.
Logic has difficulty dealing with webhook triggers since the data is untyped and can be complexly structured as nested objects and arrays.
