# Pre-filling a Mitti Inspection

> Carrying each Item's own data into an inspection so the operator only answers what is new.

## Advanced: Pre-Fill Inspection Questions

Mitti allows you to pre-fill specific inspection questions using question item IDs.

### Mobile App Pre-Fill Format

```
iauditor://template/new_audit/<template_id>?<item_id>=<response>
```

**Example with QRtub URL Templates:**

```
iauditor://template/new_audit/template_fcbc86fd41a74180921347e4be53bdf2?8f2f287e-be6e-470c-a2e2-a0fd8ab966ae={{item.assetID}}
```

Where:

* `template_fcbc86fd41a74180921347e4be53bdf2` is your Mitti template ID
* `8f2f287e-be6e-470c-a2e2-a0fd8ab966ae` is the question item ID in your template
* `{{item.assetID}}` is the QRtub field binding — replaced with that Item's own asset ID before the link opens

**At volume:** Configure this URL once for 500 pieces of equipment. Each scan substitutes that Item's own asset ID into the link, and Mitti reads the parameter and pre-fills the matching question. No manual setup per Item.

### Pre-Fill Multiple Questions

Use `&` to pre-fill multiple questions:

```
iauditor://template/new_audit/<template_id>?<item_id_1>=<response_1>&<item_id_2>=<response_2>
```

**Example:**

```
iauditor://template/new_audit/template_fcbc86fd41a74180921347e4be53bdf2?8f2f287e={{item.assetID}}&a2e2a0fd={{item.location}}
```

**Important notes:**

* You need the specific **question item ID** from your Mitti template (not arbitrary parameter names)
* To get question item IDs, see [Mitti's entity ID guide](https://help.mitti.com/en-US/000076/)
* QRtub inserts field values exactly as stored and never URL-encodes them. A value containing a space, `&` or `#` will break the deep link — store it pre-encoded in the Item field
* Very long deep links may not work consistently
