Handle signer changes from Slack
Keep an agreement moving when the person expected to sign has changed.
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
Reassign Signer
Tool to reassign a signer to a new person. use when you need to replace an existing signer on a document before signing is complete. example: "reassign the signer alice@example.com on document abc123 to bob@example.com".
Why this helps
Signer updates can get buried in conversation, leaving a document waiting on the wrong person.
- Act on a signer change while the request is visible to the team.
- Keep the document identification and replacement signer together in the instruction.
- Reduce manual follow-up when a signing contact changes.
Setup
Build it in a few focused steps.
- 1Connect Slack and Eversign to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally to handle signer changes.
- 3Write one plain-language instruction requiring an identified document, current signer, replacement signer, and a request to reassign.
- 4Select Slack's Channel Message Received trigger and choose a channel for run reports.
- 5Test with one real signer-change request and verify the replacement on the intended document.
Questions about this workflow
Will this reassign a signer on any document mentioned in Slack?
The instruction should require a clear reassignment request and enough information to identify the document and both signer identities.
Can it replace a signer after signing is complete?
The Eversign action is for reassigning a signer before signing is complete. Check the document status before relying on this workflow.
