Hmm, looks like it’s not possible.
It is highly recommended that requests sent to Make’s Custom Webhook module should be in JSON if possible.
A possible workaround I can think of is to use Zapier as the intermediary to parse the FormData into JSON, before forwarding it to your Make webhook as JSON, so that you can apply the “JSON Pass-Through” option to YES.
Unfortunately there is no “FormData Pass-Through” option, and Make just converts it all into variables.
I’m sure you and others would agree that this is a nice feature to have.
You can submit this suggestion to the Idea exchange, under App improvement ideas](https://www.make.com/en/app-improvement-ideas/).
Don’t forget to search for it first, just in case someone already suggested it, so that you don’t end up creating a duplicate.
