Currently, the Virtuance Marketing Suite does not have a tour ID number, but there is a workaround for you if you use this MLS!
When you're creating or editing their listing, under the Media section (page 5 out of 8) there should be an option to change the tour type to "URL Large Window".
You can then copy and paste your listing website link directly into this text box, eliminating the need to use a tour ID number. If you're still having trouble, we recommend contacting IRES support directly so they can guide you to the exact place within their system.
