403 Forbidden - Some users cannot be imported. How to fix it?
If you only started the work with the Proactive Campaigns app and see the next error: ‘Some users cannot be imported,’ this means that your Zendesk account does not allow mass user import.
No worry, as this option is disabled by default. All you need to do is to contact the Zendesk support team and ask to enable the mass user import. Then you can start a campaign again.
In case of questions or problems, contact our certified support agents.
