Hi Henry,

Thank you for submitting this feature request! I looked into this and confirmed that the NextRoll API does support Personal Access Token (PAT) authentication as a documented alternative to OAuth2. 

I've created an internal feature improvement ticket to add PAT authentication as an alternative auth mode. While I can't provide a specific timeline, your request has been logged and will be considered in our prioritization process.

To help set priority, can you elaborate on your use case and why the current OAuth authentication doesn't work for you?

Thank you for helping improve the AdRoll connector!
