Using Freshdesk API to create a new ticket

Hello,

I'm not from a coding background so I'm struggling a little. We have a scenario where we do not want customers to reopen 'Closed' tickets as we want Freshdesk to open a new ticket. As this is not part of the default scenarios/actions, I have read that this needs to be done via the API.

I've created a rule, based on the ticket status and currently just from a specific requester (my test email address) and have asked it to create a new ticket via the API. I have, unfortunately, received 2 automated emails from Freshdesk explaining that the rule is not working, however it does not detail what is wrong, nor can I find log files within the UI to explain what is going on to give me the slightest clue what is wrong.

This is my API configuration so far: 

Trigger webhook

Request Type: POST

URL: https://ourdomain.freshdesk.com/api/v2/tickets

Requires authentication: currently unchecked, however I have used my API key AND my username and password, neither have worked

Add custom headers: unchecked (not required)

Encoding: JSON

Content: Simple

(Subject, Last Public Comment, Source, Ticket Type)

This is all the information we need, currently.

Could somebody with some expertise, please provide an insight into where I am going wrong, or what I have maybe not configured? 

Thanks in advance,

Simon
