Outbound: keep stakeholders informed
Rills proposes each Slack action before it runs, so nothing posts or gets created without your sign-off. Review and approve from your phone in seconds.
Going the other way? Slack to Calendly
The Calendly Slack integration on Rills is built for solopreneurs and small teams who want their scheduling data to drive real Slack workflows, without anything posting or being created behind their back. When a meeting is booked, cancelled, or marked a no-show in Calendly, Rills proposes a matching action in Slack and waits for your go-ahead.
This is how calendly to slack automation works on Rills: each trigger from Calendly queues a proposed Slack action. You get a notification on your phone, review the details, and swipe to approve or reject. Approvals and logic are always free. You only pay when an action actually runs. The system learns from your decisions over time, so the proposals get smarter.
In practice, this means a new booking can spin up a dedicated Slack channel for that meeting. A cancellation can pull the conversation history from that channel before you archive it. A no-show can create a follow-up coordination channel so nothing slips through the cracks. All of it runs only after you say so.
When a new event is scheduled in Calendly, Rills proposes a dedicated Slack channel named after that meeting. Your team gets a single place to share prep notes, docs, and context before the call happens.
Build this workflowWhen a new event is scheduled in Calendly, automatically create a dedicated Slack channel for that meeting to centralize discussion and resources.
When a Calendly event is cancelled, retrieve the conversation history from the associated Slack channel to document discussion before archiving.
When an invitee is marked as a no-show in Calendly, create a Slack channel to coordinate follow-up with team members and track rescheduling efforts.
Triggers when a contact is removed from the Calendly organization's contact list. The event names the contact but carries none of its details, so capture those from Contact Created or Contact Updated first.
Triggers when a new Calendly event type — a bookable meeting template — is created. Does not fire for one-off ("Adhoc") event types, only for standard ones.
Triggers when any field on a Calendly event type changes — its name, duration, questions, locations or whether it is active. Calendly sends no before/after diff, so which field changed is not stated.
Triggers when someone submits a Calendly routing form. Fires whether or not the submitter went on to book, which is the only way to see form abandonment — a `result.type` of `custom_message` means the routing ended without a booking.
Triggers when a contact is added to the Calendly organization's contact list, by an invitee booking or by a direct write.
Triggers when a host marks an invitee as a no-show for a meeting. Marking is a deliberate act after the meeting, not automatic detection, so this can arrive hours later — and it works on past meetings.
Triggers when a host removes an invitee's no-show mark, undoing a mark made in error. Does not fire when the meeting itself is cancelled or deleted.
Triggers when a booking on a Calendly event type is cancelled, by either the host or the invitee. Fires once per invitee. The half of a reschedule that drops the old booking fires it too, with `rescheduled` true and `new_invitee` set.
Creates a new public or private channel in your Slack workspace to organize team conversations around specific topics, projects, or departments.
Retrieves a chronological list of messages from a Slack channel, allowing you to access conversation history with filtering by date range and pagination options.
Find specific channels across your Enterprise Slack workspace by searching by name, type, or other criteria. This helps you locate the right channels for collaboration without manually browsing through your entire workspace.
Find specific messages, files, channels, and team members across your Slack workspace to quickly locate information without manual browsing.
Verify whether your Slack workspace has AI-powered semantic search enabled, so you know if natural language queries will work with your assistant integration.
Change a public Slack channel to private to restrict access and control who can view the channel's messages and history. This is useful when a channel's content needs to become confidential or limited to specific team members.
Create a new Slack Canvas to share rich, formatted content with your team, enabling collaborative editing and better organization of information directly within Slack.
Move inactive Slack conversations out of sight while preserving all message history and making the channel read-only. This helps keep your workspace organized without losing important past discussions.
When a Calendly event fires, the agent drafts the Slack action and pauses.

Create a Rills account at no cost. No credit card is needed. Your 14-day trial gives you full access to set up and test automations before any action runs.
In the Rills dashboard, go to integrations and authorize Calendly. Rills will read your scheduling events but will not modify anything in Calendly without your approval.
Authorize Slack from the same integrations panel. Rills will request only the permissions needed to propose and run the actions you configure.
Select 'Calendly scheduled event created' as your trigger and 'Create channel' as your Slack action. This is the most common starting pairing: a new booking automatically proposes a dedicated Slack channel for that meeting.
When a Calendly event fires, you will receive a notification on your phone with the proposed Slack channel details. Review it and swipe to approve. The channel is created instantly, and your automation is live.
Start a free Rills trial, then connect your Calendly and Slack accounts from the integrations dashboard. Pick a Calendly trigger, choose a Slack action, and Rills handles the rest. No code required. Your first approved run can be live in under ten minutes.
Rills offers a free 14-day trial with no credit card required. Approvals and logic are always free. You only pay for actions that actually run in Slack, so reviewing and rejecting a proposed action costs nothing.
Yes. When Calendly fires a scheduled event trigger, Rills proposes a new Slack channel for that meeting. Once you approve from your phone, the channel is created instantly. You stay in control of naming and timing without doing the work manually.
By default, yes. Every proposed action waits for your explicit approval before running. Over time, Rills learns from your decisions and can surface smarter defaults. You can also configure rules to approve certain routine actions automatically once you trust the pattern.
Rejecting a proposal cancels that specific action without affecting anything else. The Calendly event is unaffected, and Rills logs your decision to improve future proposals. Nothing is created or posted in Slack, so your workspace stays clean.
It works well for both. Solo operators use it to keep client meeting channels tidy without manual setup. Small teams benefit from the shared approval queue, which ensures one person always reviews before Slack gets cluttered with auto-generated channels or messages.
