Creating webhooks generates "unable to parse the type of this backend API" error

I’m sorry I forgot to reply here.

Turns out it’s completely normal to have that warning pop up! It actually doesn’t indicate an error at all!!!

The warning is there to let you know it isn’t done yet. When it’s like that, you trigger the API on the other end and it will receive it, then you can save it and everything should be good. It was a while ago so I’m forgetting the exact sequence, but the important takeaway is: this is not actually an error!!!
