The main idea of this feature request it's to receive an webhook when something external occurs.
Like: I create an payment on typebot, the customer paid, and I receive from my payment method the POST request on typebot to show an message to the customer notifying that his payment has been received.
This will prevent a lot of pooling's that a lot of users need to make to recognize that some payment has been received.
Actually I think that it's needed use an external integrator, but having it on Typebot will be cool
