HelpShelf works alongside whatever you already use. Your agent answers what it can, and hands everything else to your existing support channel.
For live chat, connect Crisp, Freshchat, Help Scout, Groove, or Kayako by pasting one widget ID, or connect Intercom and Zendesk over OAuth. WhatsApp, SMS, and Facebook Messenger need only a number or page ID.
For content, import your existing articles from Freshdesk, Zendesk, or Intercom so your agent answers from knowledge you've already written.
See Connecting live chat and Contact options.
