Frequently asked questions
What does the Threadly Cal.com integration do?
Threadly is an app for Slack. With Cal.com connected, any Slack message can carry a booking button for one of your Cal.com event types. Clicking it opens a time picker in Slack, and the booking lands in your Cal.com calendar.
Does it work in Slack Connect channels?
Yes. Customers and partners in shared channels can book without leaving their own Slack workspace.
Can I send the booking button to many channels at once?
Yes. Pick channels or a segment and Threadly posts the message to each one, then shows which channels clicked or booked.
Can each customer get their own CSM’s booking link?
Yes. Merge fields can insert the right Cal.com link per channel, for example from the HubSpot owner field. Round-robin and collective event types work too.
