Find an open time for a prospect meeting
Check your calendar while you have the prospect context in front of you, then get a short list of available meeting times.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Find free slots
Finds free/busy time slots in google calendars for specified calendars within a defined time range (defaults to the current day utc if `time min`/`time max` are omitted), enhancing busy intervals with event details; `time min` must precede `time max` if both are provided.
Why this helps
Scheduling a prospect meeting can mean switching between lead context, availability checks, and a reply.
- Check calendar availability for the requested time range.
- Use prospect context from Apollo when preparing meeting options.
- Get a concise set of candidate slots to share.
Setup
Build it in a few focused steps.
- 1Connect Apollo and Google Calendar once in the Notis portal.
- 2Create an automation by describing the result you want, in plain language or in Automations, New Automation.
- 3In one instruction, ask Notis to use the incoming request and relevant Apollo prospect context to check availability and return candidate meeting times.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real prospect and a request that includes a date range and meeting length.
Questions about this workflow
Does this send an invitation to the prospect?
No. This workflow finds free slots. Use the returned options to coordinate a time, or create a separate workflow for event creation.
What does the webhook request need?
Include enough information to identify the prospect and the time range to check. Provide the meeting duration in the request or instruction.
