ASP webform post_action problem

Hello, I am using the Web SDK 2.0 for ASP.Net MVC webform ASPX.
I am able to show Duo in iframe. But I could not find the way to make post_action call method in cs.

What should I put in this field?
post_action: ‘ResponseAction’

The cs method is
public void ResponseAction(string sig_response)

Hi @steve21, I think I am not understanding your question correctly (I am not skilled when it comes to our API to be honest), but the post_action should be the URL to POST the signed response to. Does that help at all? If not, hopefully someone else who knows what they’re doing can chime in :grin:
