So you want to start a faucet using EC to payout to your users. I will tell you how to apply and make your API keys in this guide.
First you need to go to the top right corner and find your username and click on the dropdown menu there.
You will then be directed to a page where you will need to fill out site information and upload a file to the server to confirm you are the owner. Don’t worry, this doesn’t mean you will be linked to that domain only.
Make sure that the site you add is working as it should or you will be declined for that reason. Now wait the 24 hours to be approved.
When you have been approved please go to the site owner from the same menu and you will be directed to the add site page where you can fill in Name, site URL, user token (user token can be anything) reward, currency and time between each payment. When thats done just click Link My site and you are done. You can see API key on the list of site page.
On the Add site page you can also find PHP libary and EC faucet auto script that you can use for your faucet or use the API documentation if you made your script your self.
