POST https://sampleHostName/transformations/

This endpoint is used to run the transformation based on an already created configuration. Sending a post request will submit a background processing job that is able to report progress back to the same transformation instance that you can query by the transformation ID.

First run of the transformation will process the whole source iModel and push data to the target iModel. Only one transformation job can run on the same target iModel at the same time. Consecutively submitted jobs for the same configurationId will only process changes to the source iModel.


Requires Authorization header with valid Bearer token for scope transformations:modify.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.


You must have imodels_write assigned at the target project level and imodels_read assigned at the source project level within related configuration. If permissions at the project level are not configured, then you must have same assigned at the iModel level.

Alternatively, you must 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. For more information about User Management see Bentley Communities Licensing, Cloud, and Web Services wiki page.
