Download API definition:

PATCH https://dev-api.bentley.com/imodels/{id}/locks

Acquires requested locks on specified objects. Lock - the right to modify a specific type of data within the iModel. For more information on Locks see working with Locks via iTwin.js client libraries.

Note: Lock types have been removed for this API and should be ignored.

Object ids Limit: Currently there can be at most 1000 object ids in a single request.

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 page.

Authorization

To release any Locks (set LockLevel to none) user must have imodels_manage permission assigned at the iModel level. If permissions at the iModel level are not configured, then user must have imodels_manage permission assigned at the iTwin level. To acquire or realese Locks that the user owns imodels_write permission is enough.

Alternatively the user should be an Organization Administrator for the Organization that owns a given iTwin the iModel belongs to.

For more information please refer to Account Administrator documentation section on Access Control API documentation page.
