Access iModels data using OData v4 interface

imodels-odata

---

Retrieves all Groups (OData Entities) of an iModel Mapping. This endpoint can be used as an OData feed.

iModel Mappings can be managed using [Reporting API](/apis/insights/).

### Mapping Support

Direct data query using iModel [Mapping](/apis/insights/overview/) supports a subset of available [Mapping](/apis/insights/overview/) configuration options. Unsupported properties will be excluded from results.

Supported iModel Mapping configurations options:
- [Group](/apis/insights/operations/create-group/) - All query types supported
- [GroupProperty](/apis/insights/operations/create-groupproperty/) - All property selection supported
- [CalculatedProperty](/apis/insights/operations/create-calculatedproperty/) - All calculations are supported
- [CustomCalculation](/apis/insights/operations/create-customcalculation/) - All operators supported

### Notes

This is an OData v4 compliant endpoint.

This endpoint should only be accessed using OData compliant libraries and tools.

Use of these endpoints directly is not prohibited, however we recommend understanding the [OData protocols and conventions](https://www.odata.org/documentation/) first.

### Authentication

Requires `Authorization` header with valid Bearer token for scope `itwin-platform`.

For more documentation on authorization and how to get access token visit [OAUTH2 Authorization](https://developer.bentley.com/apis/overview/authorization/) page.

### Authorization

User must have `imodels_webview` permission assigned at the iModel level and at least `imodels_webview` permission assigned at the Project level. If permissions at the iModel level are not configured, then user must have `imodels_webview` permission assigned at the Project level.

Alternatively the user should be an Organization Administrator for the Organization that owns a given Project the iModel belongs to.

An Organization Administrator must have at least one of the following roles assigned in User Management: Account Administrator, Co-Administrator, or CONNECT Services Administrator.
