WordPress plugin
The installation of Uhmi on your WordPress website.Installation instructions
Install the plugin on your WordPress website.
When installed, you’ll find Uhmi in your menu. After adding the API keys to connect your Uhmi account, you’re ready to start.
How it works
Go to a post or page and fill in the title, price and other content details. Then, use the Uhmi shortcode [uhmi] ... [/uhmi] to wrap the paid part of your content. Or, add [uhmi] without the closing tag and all content below [uhmi] will be the paid part of your content.
You can place anything inside this shortcode: photos, videos, music, software, text, PDF’s, you name it. The content inside this shortcode will only be visible after the visitor has paid.
Tip: Give your visitors a preview of what they are about to pay for. For example: add the first paragraph of your article; a lower-res version of your photo; or a thumbnail of your video.
