I am trying to implement my site's form processing as described here (this is the same form processing that webflow uses internally, I wish to implement it on my own server).
It is working great! For the most part. I have all parts working as described, except the success message and fail message. In webflow, you can design a response that the form will respond to.
I am not sure how to make the form react to these, as the official method is not described. If anyone knows how I can set up this part, it would be much appreciated.
