4. Troubleshooting:

If you experience this error: Plugin 'PlayFab' failed to load because module 'PlayFab' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.

Your Unreal project is not set up to be a C++ project. Here is a tutorial that will help fix this problem. http://idkudk.blogspot.com/2015/02/how-to-get-plugins-to-package-correctly.html

General troubleshooting:

For a complete list of available APIs, check out the online documentation.

4.b Known Issue:

In Unreal 4.25, there is a step that is highly recommended:

Fix it in the Unreal Editor GUI:

Open Unreal Editor for your project
Edit -> Project Settings ... -> Engine -> Network
At the top of the Network section is the checkbox "Verify Peer".
Toggle it off.
Save All. (ctrl + shift +s)
Toggle it on.
Save All. (ctrl + shift +s)

Fix it in the files:

{Project}/Config/DefaultEngine.ini
Add/Replace these lines:
- [/Script/Engine.NetworkSettings]
- n.VerifyPeer=True

5 Limitations

This sdk is meant for use with a network connection. It relies heavily on HttpModule which is known in Unreal Engine to not be threadsafe. https://udn.unrealengine.com/questions/526017/view.html "HTTP requests are only supported to be created/destroyed on the main thread."

If you want to step around this Unreal Engine limitation, you may clone Epic's Unreal Engine source code and enable FORCE_THREADSAFE_SHAREDPTRS in SharedPointerInternals.h https://udn.unrealengine.com/questions/252125/view.html and load your project with that built version of Unreal.
