I was able to create a ticket using the API. However, I'm having problem with the API key and the IP address. It requires that the IP address I put is the IP address of the machine where the OSTicket is hosted. And when I try to call the API, regardless of which machine I use, it successfully creates a ticket. This is problematic because anyone can create a ticket. What I want to achieve is only the API call from IP_address_1 should be successful. And all requests from other IP addresses should be blocked. How will I be able to achieve this?
