Nintex/SharePoint 2013 on prem
Outside of Nintex I can manually format a url to query a 3rd party url to receive a token for futher api work.
When I use a web request action either post or get I keep receiving the following error message:
"Error performing web request. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
For the web request action I'm using a farm account for authenticationI've looked in CA>Security>Manage Trust as per other posts. There is no 3rd party certificate for the above. There shouldn't be. Do I need one ? Not sure why as outside of Nintex workflow it works without me knowing the certificate.
I'd try the following:
1) Try to get the response on a Nintex Form
2) Try to build my Proxy Web Service. So the call will be WebRequest Action >>> your ProxyWS >>> your 3rdpartyWS
