Turn an event link into a QR code

Prepare a scannable event link for a check-in sheet, printed sign, or quick attendee 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

Generate Barcode or QR Code

Tool to generate barcodes or qr codes using zebra crossing (zxing). use when you need a barcode or qr code image from text values.

Why this helps

Making a QR code from an event link requires another tool and another small task to remember.

  • Create a code from an event URL already shared with the team.
  • Make a link easier to scan from a printed handout.
  • Keep the generated code with event planning messages.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Api2pdf to Notis once in the portal.
  • 2Create an automation in the portal or ask Notis conversationally.
  • 3Describe one instruction to generate a QR code from an event URL when the channel message requests one and reply with the image.
  • 4Select the Slack channel-message trigger and choose a channel for run reports.
  • 5Test with a real event URL and a clear request for a QR code.

Questions about this workflow

Can the code point to any event page?

The QR action can encode text values such as the event URL, provided the message identifies it.

Does sharing a URL alone generate a code?

Specify that Notis should generate one only when someone asks for a QR code.
