Access form data in event-triggered function

I have a function that is triggered by a form submission with submission-created. I want to access the form fields submitted in the function, but cannot see how to access them.

I submit the form using the following:

    fetch("/", {
      method: "POST",
      headers: { "Content-Type": "application/x-www-form-urlencoded" },
      body: encode({ "form-name": "telephone", phonenumber: phoneNumber }),

I then try and access the phonenumber field like so:

const params = querystring.parse(event.body)
const telephone = params.phonenumber || “Not Set”

The above returns ‘Not Set’ and I cannot see any other way to access the data. Any points would be useful.

Hiya David!

I wonder if you could try a pattern like the one in @cfjedimaster’s blog post here:

He has a pretty good walkthrough and seems to parse the event body as JSON first which may help you out.

Yes that did it.

Get the function data with

And the form values are in the data block of the JSON
