I want to integrate this in my website. How can i make the script whitelabel to my domain rather than it showing pickaxe?
You cannot white-label the actual embed code. The actual source code of the embed needs to reference Pickaxe’s URL in order to work.
If that’s really important to you, I suggest you embed using the script embed instead of the iframe. This is more difficult, but you will be able to hide the pickaxe url in the header and refer to the embed simply using a div.
