Creating a new user account via web link http post

[trappedatuf]

Right now, my current software takes orders on my website and creates an entry in our seperate database system.

 

I can have it format a string that can be just entered into a browser window and it will then create the account in WHMCS... that is if WHMCS accepts GET requests.

 

For example: http://www.mywhmcslink.com/admin/clientsadd.php?firstname=John&lastname=Doe&companyname=Test%20Company&email=johndoe@email.com (etc...)

 

Then if I paste that link into a browser it will call WHMCS and create that account. Now the only thing is that it will have to be a public function I am sure, so if someone could give me some advice on how to do this it would be much appreciated.

 

PS: I know I could have my other software just add it the client info to the WHMCS database directly by an internal function I write, but I would rather do it the link way because it would be much easier.

 

Thanks for the help,

Dave
