Why Connect Close to Notion?

Close uses a REST + Webhook API while Notion uses REST, requiring careful middleware to translate data formats between the two platforms

Reporting across Close and Notion requires painful manual exports and spreadsheet merges

Transaction data in Close requires manual verification against Notion, increasing audit risk

No single source of truth when leads live in two disconnected tools, so staff second-guess which system has the correct information

Close limitations compound the integration challenge: smaller integration ecosystem than major CRMs means some connections require Zapier rather than native integrations

New team members take longer to onboard because they must learn manual workarounds to keep Close and Notion aligned

Client engagement details in Close and time-tracking data in Notion do not align, making billing inaccurate

How We Help

Our Harvard-educated consultants build a sync that eliminates that waste permanently. On the technical side, Close uses a REST + Webhook API with API key authentication, and Notion authenticates via Bearer, which our team handles as part of the build.
