Question

How is it possible to post form data to an external rest api?

At the moment i have an html form:

Answer 1

Let me contribute to the accepted answer since I don't have enough reputation to comment. Rather than pick all the form inputS one by one into a model, you could do the following

var model = this.forContollname.value

Then you could call the following

 var values = JSON.stringify(model)

The values can then be passed into your post method. I hope this simplifies the process for someone with a large form.
