YNAB authentication

YNAB supports managed and customer-owned OAuth

Use Composio-managed OAuth for the standard connection flow. Create a custom auth config with the customer's YNAB client ID and client secret when they need control over the provider app. For custom OAuth, register the exact redirect URI shown by the current Composio auth-config flow.

If YNAB reports that an application is restricted, review the YNAB app's current review and access-token restrictions. An app intended only for its owner and an app distributed to unrelated users can have different provider review requirements. Do not promise a provider approval date.
