Help with post variables to get Strip webhook data

Wappler General

I’m trying to pull some webhook data into my webhook. The other data I am able to extrapolate, just not sure what I"m doing wrong on trying to get the data that I need.

This is from my post variables:

And this is screenshot of the data I am trying to get to:

If no other objects are potentially added to custom_fields, then this will work:

$_POST.data.object.custom_fields[0].dropdown.value

But since it is an array, it is safe to assume there could be multiple values, so you need to do a lookup on some unique key:

$_POST.data.object.custom_fields.where('type', '==', 'dropdown')[0].dropdown.value

That did the trick Ken! Thanks a lot.

So how do you know that you would need to use the [0] index from looking at the JSON?

In the POST json, anything inside square brackets [ ] is an array. Arrays can be referenced by their index number, in this case 0, which is the first item in the array.

yeah that makes total sense! duh. I’ll know next time
