Want to see it working first? Try the live OpenCart demo store, then install it on your own shop below.
Install the module
Upload and install the Filecheck extension from Extensions → Installer, then enable it under Extensions → Modules.
Add your keys
In the module settings, enter your publishable key and secret key from the dashboard. Save. Once saved, your active workflows will automatically load as a dropdown.
Choose a default workflow
Select your default Workflow from the dropdown menu to apply it across your catalog.
Enable per product
On a product edit screen, enable Filecheck, tick Require upload, and select the specific workflow from the loaded dropdown list (or leave empty to inherit the default). The Element renders on the product page and gates Add to cart until a file passes.
Verify after purchase
Use your secret key server-side to fetch the job and download the validated file. See Verify jobs.
