Investigating
We are experiencing issues with connecting to an existing listing via the API - calling the Listing Imports API to create a listing import for an existing listing is returning a 403 "no_access" error. Note that this error affects XML listings only. While we work on a resolution, you can still merge with an existing listing on the sync page. We'll post an update soon.
