What's the difference between Webhooks and POSTing submitted data?

I'm trying to create a server-side (mine) handler for a Custom Thank-You page that fires after a form is submitted to your server. I'm working from an ASP.NET MVC backend and prefer POSTed forms to JSON data if that's relavant.

I'm seeing references to POSTing data and seeing references to Webhooks without seeing a document that clearly defines the difference(s).

thx

Hi,

Here is a great read on the difference between using API's to POST data vs. using webhooks:

Basically API's package data based on a pre-set list of conditions, then post it to the server and wait for the response.  Webhooks skip the API packaging and send the data whenever it is available.  Please let us know if there is anything else we can assist you with and we will be happy to help.
