the supported IAB API frameworks for the given impression:

• 1 - VPAID 1.0
• 2 - VPAID 2.0
• 3 - MRAID-1
• 4 - ORMMA
• 5 - MRAID-2
• 6 - MRAID-3
• 7 -  OMSDK

separate multiple values by a comma (e. g. iabframeworks=1,2,7) 

requests a specific type of response; 

mandatory for video ad requests; if missing, Equativ will return the default ad response which is based on the placement setup in Equativ's system (format type: Web, App (SDK) or Video); see also Create placements 

values can be either literal (e. g. out=js) or value (e. g. out=1) :

• Javascript: out=js or out=1 
• Nonrich: out=nonrich or out=2
• Iframe: out=iframe or out=4
• XML: out=xml or out=8
• JSON: out=json or out=16
• VAST: out=vast or out=32 (calls a VAST ad with version 4.0 or lower; read about calling specific VAST ad versions below)

Calling specific VAST ad versions:

• out=vast4.2 - calls a VAST ad with version 4.2 or lower
• out=vast4.1 - calls a VAST ad with version 4.1 or lower
• out=vast4 or out=vast or out=32 - calls a VAST ad with version 4.0 or lower
• out=vast3 - calls a VAST ad with version 3.0 or lower
• out=vast2 - calls a VAST ad with version 2.0

the key=value targeting of the ad (e.g: gender=male); 

In case of multiple keywords or key=values, use a semicolon (;) to separate them (e.g. color=green;color=red;sport;football). 

The comma character (,) must never be used as a separator because this character will be considered as part of the key=value or keyword itself. 

Read more in Set keyword targeting.

• m - master request; indicates that the request should be counted as a page impression; use m only for the first request from a given page; all subsequent requests from the same page should use s
• s - slave request; indicates that the request should be counted as a regular ad impression; do not use s for the first request from a given page;

parameter is optional; if absent, the default value is used: m (master) in case of OneCall or s (slave) in case of standard call

the ad break; possible values:

• 0 - default
• 1 - preroll
• 2 - midroll
• 3 - postroll
• Not set for overlays

default value: 1

a boolean indicating of Server side Video ad rules are enabled or not.

• “true” - Server side Video ad rules are enabled 
• “false” - Server side Video ad rules are disabled

You can also set this parameter in the optional JSON configuration file using the same syntax. If the parameter exists in both ad call and JSON configuration file, the setting in the JSON configuration file will override the setting in the ad call.

the number of passback ads; defines the number of additional ads to be delivered with the VAST response for failover (fallback) purposes (see "ad buffet" in the VAST specification); 

default (if pb is not specified): 4 passback ads, if available on the placement; a maximum of 10 passback ads can be served; 

pb=0 disables passback ads entirely 

ⓘ Note: only insertions without any video ad pod position targeting can be served as passback ads; read Set video ad pod position targeting for more on video ad pod position targeting

a boolean indicating of Server side Video ad rules are enabled or not.

• ssar=0 deactivates server side ad rules and activates client side ad rules
• ssar=1 activates server side ad rules and deactivates client side ad rules

a boolean indicating if noad is counted client-side or server-side; noad occurs when more ads are requested than available on the placement;  noad counting is done for reporting and forecasting purposes;

• s for server-side counting (default)
• c for client-side counting (used in case of Equativ's video plugin or Embedded Ad Manager); in case of client side counting using standalone VAST requests, noad should be counted as described in section “Counting empty inventory in case of standalone VAST requests” in Supply in-stream video inventory: get started

The server side counting method (vcn=s) means that Equativ counts empty (unmonetized) inventory server side. Empty inventory occurs when the number of ads returned by Equativ is less than the number of ads requested by the pod size (ps=) parameter or by the maximum ad break duration (mabd=) parameter in the VAST request. Empty inventory is counted with the report metric "No ad". Keep in mind: In case of client side counting, missing ads should be counted on the client side as described in “Counting empty inventory in case of standalone VAST requests” below.

the video integration type passed by Equativ’s video plugin; possible values:

• 1 - Instream Plugins
• 2 - Instream Embedded Ad Manager
• 3 - Outstream synchronous formats (obsolete)
• 4 - Outstream asynchronous formats
• 5 - Server side ad insertion (SSAI)

the VPAID version:

• 0 - VPAID not supported (mandatory if VPAID is not supported at all)
• 1,2 - allows VPAID 1.0 or VPAID 2.0 creatives; default option
• 1 - allows only VPAID 1.0 creatives
• 2 - allows only VPAID 2.0 creatives
