The plugin serves as a versatile framework, allowing for easy addition of new providers. To do this, explore the Flow directory in the plugin’s code. The Flow.h file is the foundational interface that all flows adhere to. For a practical example, see the External/AuthorizationFlow class, which demonstrates OAuth Authorization Code Flow implementation. This modular design means adding a new provider is as simple as creating a new class and defining a few basic properties, similar to the External/FacebookAuthorizationFlow class.

The plugin functions by using a universal login node that selects the appropriate implementation based on the config parameter type. This configuration occurs in UOAuthPP_SubSystem::Login. To integrate an additional provider, include it in this section.

For assistance with implementing a new provider, feel free to reach out to me on Discord at taigi100.

I’m looking to reorder the parameters in the config object, but I’m uncertain if Unreal Engine allows for this. If you know how to achieve this, I’d appreciate your guidance.
