SD Release can retrieve the Joomla! Extensions Directory reviews and can copy these to your website! You can show these reviews by creating a review tab template and tab, however, some setup is required before you can start showing them.
Every extension that is listed in the JED has its ID. You can find this ID by opening your extension, clicking the reviews tab and hover over the Write Review button. The URL of this button should look something like
https://extensions.joomla.org/write-review/review/add?extension_id=13100. Notice the extension_id? You need to enter that ID into the JED Extension ID field of extensions.
Then set up the cronjob. SD Release comes with a cron command to automatically sync the reviews. You need to execute the
/cli/sdr-getreviews.php file once every day using cronjobs on your webserver. Contact your hosting if you are not sure how to set up cronjobs.
