iModel Connections API is a cloud-based synchronization API meant to synchronize the data in Input Files and iModels. It allows users to establish links from their design files to iModels, hosted in Bentley's iModelHub. Users can synchronize updates to their design files.

redirectUrl

OAuth access token with scope `synchronization:read`

Authorization

Setting to `application/vnd.bentley.itwin-platform.v1+json` is recommended.

Accept

This response indicates that request lacks valid authentication credentials. Access token might not been provided, issued by the wrong issuer, does not have required scopes or request headers were malformed.

application/json;InvalidAuthorizationScheme

This response indicates that the user has sent too many requests in a given amount of time.

The number of requests exceeds the rate-limit for the client subscription.

Create a configuration that defines how data is processed and synced to iModels with the specific connection.

### Configurations

#### reclassifyDgnElements

Enables connector to change the base class of an element if its current classification comes from the Generic schema.
The default value is false.

If this configuration is set to true:

- Every Generic element in the model will be re-processed, so expect a longer synchronization job.
- Elements that are derived from a BIS class will not be processed.
- Elements that did not change in the source file may appear modified in iModel if you use the Changed Elements API.
- Elements that changed will appear deleted and added in iModel if you use the Changed Elements API.
- Suggest setting this configuration with caution and per required run basis, not perpetual.

Use case example: If you have been advised by Bentley support that the Connector has added additional support for your files' disciplines (e.g. additional BIS schema alignment), then this option should be enabled on the next run to opt-in to the updated alignment.

#### ignoreDgnAttachments

Enables skipping of all reference attachments. As a result, only the master file is synchronized into the iModel. Only applicable for .dgn and .dwg files.
The default value is false.

A reference file could have a transform/ level override/ symbology override when attached through a master file. None of these settings will be available if the files are processed individually and could result in data not matching the intended design.

#### enableSheetsAndDrawings 

Controls sheets and drawings synchronization. If enabled all sheet models and relayed drawings will be synchronized to an iModel.
The default value is false.

### Authentication

Requires `Authorization` header with valid Bearer token for scope `synchronization:modify`.

create-connection-configuration

Invalid request to create a configuration. Request payload might be missing some of the required properties.

application/json;InvalidConfigurationRequest

---

Create a configuration that defines how data is processed and synced to iModels in the specific iModel.

### Configurations

#### clampZExtent

Enables a limit for the project Z extent maximum up to Mount Everest height (i.e.8849 meters). Works only when project extent in XY direction is defined for iModel.
The default value is false.

Display performance can be adversely affected if source data is poorly aligned or contains elements far from the project's physical location. If files cannot be corrected, this configuration would help viewers to restrict the Z extent.

Use case example: allows restricting viewport to the bounding box so that any arbitrary geometry far away from the actual design does not impact fitting the model to the viewport.

#### overrideRvtReprojectionDistance

Define distance in meters when to start ignoring .rvt file geo-location data and reprojecting graphics based on local iModel coordinates.
The default value is 0.

Reprojection happens when the .rvt file and iModel have different geographic coordinate systems. If the distance between both GCS is bigger than the number provided with the flag, reprojection will be skipped, and no errors will be reported. Otherwise, reprojection will be applied.
This configuration will have no effect if Revit was the first file synchronized to an empty iModel.

Use case example: no reprojection of Revit file is needed beyond some pre-defined radius.

#### enableFileNamePolicy

Sets the active file policy to use file names instead of GUIDs when running the connector. It is only applicable to file-based synchronization workflows.
The default value is false.

If a mismatch occurs between the active file policy and the stored file policy inside the iModel, the connector job run will fail.

Use case example: in a particular document management system, the uniqueness of files is determined by file name, while the GUID value could change; setting this configuration to true would allow synchronization jobs to recognize individual files and avoid duplicates.

### Authentication

Requires `Authorization` header with valid Bearer token for scope `synchronization:modify`.

create-imodel-configuration

imodelid

---

Create a configuration that defines how data is processed and synced to iModels in the specific iTwin.

### Configurations

#### clampZExtent

Enables a limit for the project Z extent maximum up to Mount Everest height (i.e.8849 meters). Works only when project extent in XY direction is defined for iModel.
The default value is false.

Display performance can be adversely affected if source data is poorly aligned or contains elements far from the project's physical location. If files cannot be corrected, this configuration would help viewers to restrict the Z extent.

Use case example: allows restricting viewport to the bounding box so that any arbitrary geometry far away from the actual design does not impact fitting the model to the viewport.

#### convertDgnTerrainModels

Enables terrain model elements to be processed during dgn-based synchronizations.
The default value is false.

#### squashIntermediateRevisions

Enables the creation of a single Changeset for physical and drawing elements (2D, 3D) coming from all Source Files. Separate Changesets will be pushed for any schema or definition changes.
The default value is false.

Use case example: minimize a linear timeline of the iModel changes. However, in this case, you would not be able to get information on individual Source File changes.

#### convertDgnHyperModelingSections

Enables displaying the 2D section graphics and annotations in the context of the 3D model.
The default value is true.

Use case example: typical design files include hypermodels, and the intent is to expose such information in a viewer. Refer to the sample of how to navigate between the 2D and 3D views easily: [sample](https://www.itwinjs.org/sandboxes/iTwinPlatform/Hyper-modeling) 

#### skipRvtReprojection

Ignores geo-location defined in .rvt file and overlaps the model at the local iModel coordinates.
The default value is false.

This configuration will have no effect if Revit was the first file synchronized to an empty iModel.

Use case example: multiple Revit files will need to be synchronized; if individual files are not aligned to the exact location, this configuration will bring all the models to the same place. However, we suggest enhancing the original design files with proper geographic coordinate systems before synchronization instead of using this configuration.
