This plugin is not required anymore. From Post Pay Counter v2.780 (2023-06-07), Slimstat and other visits trackers are supported natively without need of extra addons.
This little addon allows integration of WP-Slimstat visits data with Post Pay Counter. This way, you will be able to use Post Pay Counter to pay your writers per visit using the tracking functions of WP-Slimstat.
Requires both Post Pay Counter and WP-Slimstat (both free).
