Hello Playfab Team and members,
This page is the top 5 results in Google for "playmaker prefab actions".I tried importing the GitHub scripts but they are giving an error in Unity 2019.3 and being a 2016 thread I do not expect it to be supported, especially by an indie dev for so long.
The paid alternative on the asset store has not been updated since AUG 2019 with reviews of broken scripts plaguing the Store.
I would have tried the SDK Generator mentioned but I do not have the coding knowledge to do so.
So, I would like to humbly request the dev team to officially release at least an essentials pack of Playmaker scripts of PlayFab. There are still a lot of users who are developing games using PlayMaker.
That combined with Unity gives a substantial edge in game dev for faster prototyping and eventually publishing the titles.
