App Not Installed? Set a Fallback URL

iauditor:// deep links only work if Mitti is installed on the device. If someone scans and doesn’t have the app, the link does nothing. QRtub handles this automatically. When you enter an iauditor:// URL as a Destination, an amber notice appears in the editor prompting you to configure a fallback. Recommended setup: What happens at scan time:
  • Mitti installed → app opens directly to the inspection template
  • Mitti not installed → after 2.5 seconds, QRtub redirects to the web version
The Fallback URL supports {{item.field}} bindings, so you configure it once and it adapts to each Item automatically — just like the app link itself. You can also set a Fallback Message instead of a URL if there’s no web equivalent (e.g. “Please install Mitti to access this inspection template”). See App Links & Fallback URLs for full details on how fallbacks work.

Troubleshooting

Mobile app doesn’t open:
  • Ensure Mitti app is installed on the device
  • Verify Template ID format is correct
  • Check that the user has access to the template in Mitti
Web link doesn’t work:
  • Verify user is logged into Mitti web app
  • Check that the user has permission to access the entity (template, inspection, asset)
  • Confirm the entity ID is correct
Data not pre-filling:
  • You need the specific question item ID from your Mitti template (not arbitrary field names)
  • Ensure Item fields in QRtub contain data
  • Test that URL encoding is correct for special characters
  • Verify deep link isn’t too long (keep it under ~2000 characters)
Users need access: Deep links only work if users have permission to access the relevant entities in Mitti. Ensure your team has appropriate access before you produce a Batch.
