Check a Handle Only When Permission Is Clear
A permitted handle check can start from a Slack DM and return a result that stays subject to human review.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Get Gender from Username
Tool to determine gender from a username or nickname. Use when you have an alias or handle and want to infer gender from that identifier.
Why this helps
A one-off approved check can be forgotten when it requires switching from Slack to an enrichment tool.
- Starts from the DM where permission is documented.
- Avoids manual re-entry of a handle for an approved lookup.
- Keeps the inferred result in a review step.
Setup
Build it in a few focused steps.
- 1Connect Slack and GenderAPI.io to Notis once through the portal.
- 2Create an automation by asking Notis to check a username only when a Slack DM clearly records permission for that inference.
- 3Choose the Slack direct message trigger and select a channel for run reports.
- 4Try one real, consented handle and review the result before any use.
Questions about this workflow
Is a username a reliable source for gender?
No. A handle may not reflect a person's identity, and the result can be wrong. Treat it only as an uncertain inference.
Why use a DM trigger?
This workflow is for an explicit permission record sent directly to the user in Slack.
