Which CRMs work with Signal?

Native integrations cover calendars (Google Calendar natively) and common field-service tools, and everything else goes through two paths: the direct webhook, where every lead pushes as JSON into your system, and the Zapier/Make connectors, which link HubSpot, Salesforce, Pipedrive, Zoho, Monday and several hundred others without writing a line of code. The webhook payload is documented and stable: number, summary, urgency, transcript, appointment. If your CRM accepts incoming JSON or exists on Zapier, it's compatible — which is true of nearly all of them today.
