Request phone confirmation from Slack
Turn a clear request for phone confirmation into an OTP step without adding another manual handoff.
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
Send SMS OTP Verification
Tool to send SMS OTP for phone verification. Use when you need to deliver a one-time password via SMS before verifying user identity.
Why this helps
Phone verification requests can sit in a channel while someone remembers to open a second service and initiate an OTP.
- Start an OTP step from a clear team request.
- Reduce administrative handoffs for phone confirmation.
- Keep the verification action connected to its reason.
Setup
Build it in a few focused steps.
- 1Connect Slack and FraudLabs Pro once in the portal.
- 2Create an automation with a single prompt to send an OTP only for explicit phone-confirmation requests with a valid number.
- 3Select Slack Channel Message Received as the trigger.
- 4Choose a channel for run reports and test with a real consenting test number.
Questions about this workflow
Does this confirm the phone number automatically?
No. It sends an OTP; the verification result is a separate action.
Can it send messages for ordinary order discussion?
Describe the explicit phone-confirmation request required in the prompt.
