In order to use the content extractor, an API Key is required.
You must enter your customer account and go to Panel -> API Key (Link)
There you will find a series of numbers and letters that you will have to place in the Appyn theme panel.
Likewise, you will have to add your websites so that they are enabled. You can add a maximum of 10 sites. If you want more sites, you can contact us by creating a ticket.
