Most DSP platforms including Google DV360 support only single Landing page URL to be provided for a Creative. ADBRO in the meanwhile support unlimited number of static and dynamic links (they might be called "exits" in some DSP platforms) within a single Creative.
Your Account Manager will provide you with a main Landing page URL alongside the Advertisement Tag. Note that DSP previews may be limited to showing only In-Image part. Feel free to contact your Account Manager for the fully-functional preview link.
