Zinc integration FAQ

Do I need to create my own auth app to connect Zinc to StackOne?
No, you don't need an auth app. Zinc uses an API Key instead (StackOne docs also call it the "Zinc Partner API key"). Generate one in Zinc under Company Settings > Integrations, then paste it into the StackOne dashboard auth config for the Zinc connector. See the Zinc setup docs.
