Momentum allows you to integrate with Outreach, in order to, for example, add a newly created prospect to one of your nurturing sequences directly from Slack.
The steps are very simple. From any Slack channel, just type
/integr which will display the "Configure Integrations with Momentum" Slash command:
That will open Momentum Integrations Slack menu. Simply, click on Authorize and that will open a new Browser tab so you can complete the authentication flow on outreach.io.
For re-authorization, you'll need to Sign Out and Authorize again from the integrations modal.
