Keep contact details current from Slack
When a teammate shares a clear correction for an existing contact, Notis can update the Calendarhero record so the right details are available for follow-up.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Update Contact
Tool to update details of an existing contact. use when you have the contact's id and want to apply changes. example: 'update contact 507f1f77bcf86cd799439011 with a new email.'
Why this helps
Contact corrections in chat can be missed, leaving old details in place and making future coordination harder.
- Carry explicit corrections into the contact record.
- Reduce repeated use of outdated details.
- Avoid a separate manual update task.
Setup
Build it in a few focused steps.
- 1Connect Slack and Calendarhero to Notis once through the portal.
- 2Create an automation with a plain-language instruction to update an existing contact only when the person and corrected detail are explicit.
- 3Select Slack Channel Message Received and choose a channel for run reports.
- 4Test with one real correction and confirm the intended contact is unambiguous.
Questions about this workflow
Will this update contacts based on guesses?
No. The prompt should require a clear identification of the existing contact and the new detail.
What if the contact cannot be identified?
Have Notis ask for clarification instead of changing a potentially incorrect record.
