Thanks.

I have a mail with html and javascript, when user click botton into mail, call web api appian, but I get error into image.

ca you help me?

Thanks!

You cannot call an API in Appian from some HTML in an email. Any API call requires authentication. And, to be able to modify any data in Appian, that API has to use the POST method. And you cannot do a POST from a link.

ok, but if I enable web api authentication with API_KEY and I insert this api_key into header post, the authentication it should work?

Thanks!
