In case you need to integrate a third-party service, Oneteam does support a couple of these apps.
To start integrating, in Homepage select [Settings] from Oneteam menu bar.
Once settings menu is displayed, select Integrations.
Note that, Integrations and Billing are only viewable and accessible to Owner and Admin.
Once you're in Integration page, you may now select the third-party app you wish to integrate on your team.
Click the Add new integration button and select any apps you wish to setup.
Select either, Slack notification, Webhook or maybe create a custom notification for your own team.
Once you have decided, just login the necessary credentials.
You'll be all set when all necessary third-party authorization has been given.
