Edit an existing CRM (PHP, Code Ignitor)

I currently use an Excel spreadsheet to track clients, projects, and invoices. I've well-and-truly outgrown it and I've recently purchased an open-source CRM (called Perfex) to take its place. Perfex is written in PHP (with a MySQL database) and uses the CodeIgnitor framework. Perfex does ticketing and invoicing, but is weak regarding timesheets. I currently use a web-based tool called Toggl for timesheeting. Toggl has an API, and I have some VBA code that automatically creates customers and projects in Toggl from Excel. It's pretty simple code, which you can see in the attached screenshot (that's all of the code, minus a helper class to handle JSON encoding, and another to handle base64 encoding, neither of which we'll need to worry about in PHP). I'm after someone to implement the same code in Perfex. Ie: * Given a client ID and name in Perfex, you need to add a function to create that client in Toggl. Your function should return the Toggl client ID and save it to the Perfex database. * Given a project ID, project name, and client ID in Perfex, you need to add a function to create the project in Toggl. The project name should be called "<perfex_project_id> - <perfex_project_subject>". I will create the UI and add the database fields. I would like the freelancer to create the functions in the controller and model, and also write the code to call them. You can see the Toggl API at [login to view URL] There is an existing PHP library ([login to view URL]) which you are welcome to use. I personally don't think it's needed though - as you'll see from the attached VBA code it's just a single API call. Also note that I won't be adding any more Toggl integration (as this is just a stop-gap until timesheets are properly built into Perfex). I think that covers everything in a lot of detail, but if you have any questions please ask. Oh - I can give you access to my Perfex installation. You won't need to set it up on a test environment.
