Hey @shanegraham I wanted to follow up with you on this question after I talked with our SDK team about this.
OAuth is a known direction for MyGeotab integrations, and the team intends to document and officially support it for public use. However, that work is not complete yet, and there is currently no confirmed timeline for when the public documentation and supporting automation will be available.
Because of that, I would treat the OAuth credential type as experimental for now. It may work in production if you have already configured and tested it successfully, but it is not yet an officially documented or supported integration path. There is also a possibility that the current implementation could change before the supported public version is released.
If your integration requires a fully supported production authentication method, I would recommend holding off for now or continuing to use the currently documented authentication approach.
Hope that helps!
