OnCall Sync — automatically deliver leads to your tools.

Every lead, conversation, and conversion fires to your CRM, your team's Slack, or any webhook. Set it once, never look at OnCall again unless you want to.

How it works

Three steps.

  1. 01

    Pick where leads go

    Click a preset (HubSpot, GoHighLevel, …) or paste your webhook URL. Test the connection right there.

  2. 02

    We send signed events

    Lead created, hot lead qualified, call completed, booking made, sequence finished. HMAC-SHA256 signed.

  3. 03

    Your tool ingests them

    Contact created in HubSpot, deal stage updated in GHL, Slack message fired — whatever your tool does with a webhook.

Event types

Ten events. All the moments that matter.

Event
lead.created
lead.qualified_hot
lead.qualified_warm
call.started
call.completed
booking.created
booking.rescheduled
booking.cancelled
