After installing and activating the plugin, it is available in the WordPress administration area under Settings > Lightning Publisher.
At this point, the URL and API token of the Lightning Charge server must be stored.
We can find these anbagben in our BTCPay server. However, this requires that C-Lightning (instead of LND) has been selected as Lightning Node when setting up the BTCPay server.
We go to our BTCPay server in the Server Settings section. There under Services and Lightning Charge Services. In the Credential section we can find the required information.
The information from the server in the AuthendicatedUri field is entered in the Server Url field. The information from Uri goes to Public URL and the APIToken goes to API token.

Article provided with payment barrier.
After all the technical requirements for setting a paywall have been met, we will create an article that will be offered for a fee.
On this page we will show you how to add a Lightning Publisher for WordPress paywall to your WordPress article.
To do this, go to a post and switch to the text view.
In the text view you go to the place, from which the contribution is to become liable to pay costs.
At this point you insert the shortcode: [ifpaid AMOUNT CURRENCY]
For Amount you enter the amount and for Currency the corresponding currency. Please place the square brackets flush with the text. We had to insert a space here to describe the code. Otherwise, the rest of the text would have disappeared behind a paywall. So please do not insert a space after the [ifpaid XXX]
For example, you can offer the post for 5 cents, then you need to enter [ ifpaid 0.05 EUR ]. If you want to charge the item for 5 satoshi, then you enter [ ifpaid 0.00000005 BTC ].
You can also display a specific text and label the corresponding pay button.
[ ifpaid 0.05 EUR text="Für nur 5 Cent kannst Du den ganzen Artikel lesen" button="Jetzt mit Bitcoin Lightning bezahlen" ]
In the article it then looks like this:
When the reader clicks on the “Pay now with Bitcoin Lightning” button, the following payment window opens:
