Slack integration is an available option with any tier.
Other corporate communication channels like Yammer, Microsoft Teams, or Workplace, are offered as a Pro add-on at an additional fee. These integrations allow users to login to the app through their account with the above platforms. Sharing can also be utilized to extend app content and photos to the communication channel.
Shine does not offer integrations with public social media platforms like Facebook, as each organization is a private space for your network.
