Rentsync Ad Syndication API
Ad syndication API described on the public Rentsync Partners portal as programming interfaces used to "interact with rental industry professionals using Rentsync's Ad Syndication to manage their online advertising". This is the machine interface to the listing-distribution business that pushes property advertising into the Rentals.ca Network and partner portals. Documentation sits behind the same approved-account gate; no base URL, feed schema, or auth model is published anonymously.
