How to use Close

Close is built for salespeople who spend more time selling than clicking. It strips away CRM cruft, putting your pipeline front and centre so your team moves deals forward without friction. Integrated calling and email mean you reach prospects in seconds without context-switching.

How to automate Close

Native integrations

Close connects with Gmail, Microsoft 365, Twilio, WhatsApp, Calendly, Zoom, Google Calendar, Gong, Help Scout, HubSpot and more. It also lists ChatGPT and Claude. A good start is mail and calendar sync, so every email and meeting lands on the lead record.

API and webhooks

Close has a REST API and webhooks (developer.close.com/api). Use a webhook to tell your team chat when a deal moves to Won, or to create a customer record in your billing system.

MCP server

Close runs an official hosted MCP server at mcp.close.com/mcp, with OAuth or an API key. Connect an AI assistant to ask which leads had no contact this week.

No-code automation

Close lists Zapier as an integration. A simple flow: a new form submission creates a lead in Close and assigns it to a rep.

Built-in automation

Workflows and sequences handle follow-up inside Close. Start with a sequence that mixes an email and a call task for every new inbound lead.
