Log meetings held to Airtable to track show rate
When a Cal.com or Calendly meeting is completed, Master Inbox labels it Meeting held and a webhook adds the meeting to Airtable, so show rate is meetings held over meetings booked.
Why teams run it
Meetings booked flatters a campaign. Meetings held tells you if it works.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Log meetings held to Airtable to track show rate.
- Set the trigger to Meeting Completed and choose From Cal.com or Calendly.
- Add the action Add labels: Meeting held.
- Add the action Send a webhook: Send the prospect, campaign, meeting time and thread URL to your Airtable webhook.
- Save the workflow and switch it to Active.
Before you start, connect Cal.com or Calendly under Settings, Integrations.
Or create it with the API
Everything in the workflow builder is also in the Master Inbox API. This request creates the same workflow. Replace the example ids with your own label, list and campaign ids from GET /workflows/filter-fields.
curl -X POST https://api.masterinbox.com/api/api-webhook/v1/api/workflows/create-workflow \
-H "Authorization: Bearer $MASTER_INBOX_API_KEY" \
