Required tag parameters for desktop and mobile web inventory

The required parameters for tags on Mobile Web inventory are id and referrer. However, you'll need additional parameters such as width and height to monetize your inventory, unless these values have been set on the placement.

Parameter	Type	Required?	Compatible Handlers	Description
id	string	Yes	ptv, ssptv, vmap, ssvmap	The unique ID of the placement where the ad will serve. If you'd rather not pass the raw placement ID, you can pass in a combination of member and inv_code parameters. For more information, see "Target Video Attributes via Query Parameters."
referrer	string	Required for desktop and mobile web only	ptv, ssptv, vmap, ssvmap	The URL where the ad will be rendered
vcontext	int	Required to monetize inventory	ptv, ssptv	Position of the video placement. Possible Values: - 1 - Linear Pre-roll - 2 - Linear Mid-roll - 3 - Linear Post-roll - 4 - Outstream - 5 - Bannerstream - 6 - In-Feed - 7 - Interstitial - 8 - Accompanying Content Pre-roll - 9 - Accompanying Content Mid-roll - 10 - Accompanying Content Post-roll Note: For reference on the corresponding OpenRTB 2.6 fields (video.plcmt) mapped to vcontext values, see the OpenRTB 2.6 documentation.
vframeworks	int	Required to monetize inventory	ptv, ssptv, vmap, ssvmap	Frameworks supported by the player. Possible values: - 1 - VPAID 1.0 - 2 - VPAID 2.0 - 3 - MRAID-1 - 4 - MRAID-2 - 5 - ORMMA - 6 - OMID-1 Note: vframeworks supports single as well as a list of comma-separated integer values. For example, vframeworks=1,2,3 or vframeworks=1.
vheight	int	Required to monetize inventory	ptv, ssptv, vmap, ssvmap	Player height (in pixels). While not required, this parameter is recommended in order to ensure video bidders receive both width and height on bid requests.
vmaxduration	int	No	ptv, ssptv, vmap, ssvmap	For single requests, this is the maximum video placement duration in seconds. Any creative with a duration longer than this value will be excluded from the auction. For podded inventory, this is the length of the full pod.
vwidth	int	Required to monetize inventory	ptv, ssptv, vmap, ssvmap	Player width (in pixels). While not required, this parameter is recommended in order to ensure video bidders receive both width and height on bid requests.
