If you use Gumroad to sell your WordPress plugins or themes you can now use Kernl to validate those licenses before new updates are made available.
How does it work?
When you create a plugin/theme in Kernl you can select the “Validate Gumroad License?” checkbox and fill out the “Gumroad Product Permalink” field. With those two fields completed Kernl will validate the license code passed into the Kernl via the update checker against Gumroad’s public license API. If the license code passes validation Kernl will allow the update to proceed.
That’s all there is to it! If you need any help getting things set up reach out to jack@kernl.us.
