Let's see what do you need to query a document by its Id or Path.

Query a content by its Id

Following example shows how to query the document with the Id 6.

GET https://example.com/OData.svc/Root?query=Id:6

Search in a folder

You can specify a folder to search in using the InFolder param and the chosen parent's Path as its value in the query.

Following query returns the children of the folder named Calgary:

You can also specify a branch of the content repository to search in using the InTree param and the Path of the root content of the chosen branch.
