I'm an author at Envato marketplaces and I need a tiny self-hosted html file that has a small form to determine if, based on my input, a user has purchased one of my items and if he still has support included.
Both can be checked with the Envato API: [login to view URL]
I would provide e.g. the customers Envato username and the unique purchase code.
No graphical UI is required. Just plain and simple HTML.
For the development I will provide a API key and test data.
Please add API in your bid to show me that you've read the requirements.
As it's just a few lines of code I'll pay up to $10 for the job.
