+### 7. Property
+
+Property bindings represent connector-defined resources that a user browses and selects at design time (e.g. a SharePoint folder, an OneDrive file). They are child resources of a parent Connection binding and contain **arbitrary sub-properties** with resolved values.
+
+**Key Format:** `<parent-connection-uuid>.<label>`
+
+**Example:**
+
+```json
+{
+  "resource": "Property",
+  "key": "775694d9-4c5b-430f-bf47-6079b0ce8623.SharePoint Invoices folder",
+  "value": {
+    "FullName": {
+      "defaultValue": "Invoices",
+      "isExpression": false,
+      "displayName": "File or folder",
+      "description": "Select a file or folder",
+      "propertyName": "BrowserItemFriendlyName"
+    },
+    "ID": {
+      "defaultValue": "017NI543GXSYR5TZEZOBHJQNL6I2H4VA3M",
+      "isExpression": false,
+      "displayName": "File or folder",
+      "description": "The file or folder of interest",
+      "propertyName": "BrowserItemId"
+    },
+    "ParentDriveID": {
+      "defaultValue": "b!fFiPzsQBgk2xGTJUTRo5jryva9eCrqNPowK3pN2kXWKF90cVuHqnS4RUsG9j1cRt",
+      "isExpression": false,
+      "displayName": "Drive",
+      "description": "The drive (OneDrive/SharePoint) of file or folder",
+      "propertyName": "BrowserDriveId"
+    }
+  },
+  "metadata": {
+    "ActivityName": "SharePoint Invoices folder",
+    "BindingsVersion": "2.1",
+    "ObjectName": "CuratedFile",
+    "DisplayLabel": "FullName",
+    "ParentResourceKey": "Connection.775694d9-4c5b-430f-bf47-6079b0ce8623"
+  }
+}
+```
+
+**Property-Specific Metadata:**
+- `ParentResourceKey`: The key of the parent Connection resource (`"Connection.<uuid>"`)
+- `ObjectName`: The connector-defined object type (e.g. `"CuratedFile"`)
+- `DisplayLabel`: The sub-property used as the primary display value
+
+**Reading Property bindings at runtime:**
+
+Use `sdk.bindings.get_property()` to read resolved Property values:
+
+```python
+from uipath import UiPath
+
+sdk = UiPath()
+
+# Get a single sub-property value
+folder_id = sdk.bindings.get_property(
+    "775694d9-4c5b-430f-bf47-6079b0ce8623.SharePoint Invoices folder",
+    "ID"
+)
+# → "017NI543GXSYR5TZEZOBHJQNL6I2H4VA3M"
+
+# Get all sub-properties as a dict
+props = sdk.bindings.get_property(
+    "775694d9-4c5b-430f-bf47-6079b0ce8623.SharePoint Invoices folder"
+)
+# → {"FullName": "Invoices", "ID": "017NI543...", "ParentDriveID": "b!fFiPz..."}
+```
+
+The key argument also accepts a suffix — any trailing portion of the full key that uniquely identifies the binding:
+
+```python
+# Equivalent to the full key above
+folder_id = sdk.bindings.get_property("SharePoint Invoices folder", "ID")
+```
