Getting error on call a webhook in Zoho Flow from deluge.

Getting error on call a webhook in Zoho Flow from deluge.

I with to trigger a Zoho Flow via a webhook trigger by invoking a URL  from deluge.

The Zoho Flow is all set up and running smoothly - but I keep getting an effort with invoking the URL via deluge (which is running as a function with Zoho Sales IQ Bot   - Zia Skills. 

Following is my deluge code (keys randomized, of course)

// create an API to create an inquiry process request to Zoho Flow
urlCall = "https://flow.zoho.com/123456791012345/flow/webhook/incoming";
urlparams = Map();
urlparams.put("zapikey","243123412.123412341234214332142134213412421435144235");
urlparams.put("isdebug","false");
urlparams.put("email",email);
urlparams.put("name",name);
urlparams.put("subject",inquirysubject);
urlparams.put("description",inquirydescription);
resp = invokeUrl(urlCall,"PUT",urlparams);
info resp;


info resp returns the following: 

info: {"type":"security","status":"error", "info":{}}

 What I am doing wrong with this URL invoker?

Best regards,
Joe
