Open Measurement SDK support

The Equativ Instream SDK 7.27 embeds the IAB Open Measurement SDK with OMID API version 1.3.10 It therefore supports Open Measurement third-party verification tags included in your VAST ads.

Table of contents


For VAST 4.0 ads and below, third-party verification scripts must be added in the <Extension type="AdVerifications"> tag as the <AdVerifications> tag at <Ad> tag is only available from VAST 4.1.

For example:

...
<Extensions>
  <Extension type="AdVerifications">
    <AdVerifications>
      <Verification vendor="company.com-omid">
        <JavaScriptResource>
          <![CDATA[ https://company.com/omid.js ]]>
        </JavaScriptResource>
        <VerificationParameters>
          <![CDATA[parameter1=value1&parameter2=value2&parameter3=value3]]>
        </VerificationParameters>
      </Verification>
    </AdVerifications>
  </Extension>
</Extensions>
...

For VAST 4.1 ads and above, third-party verification scripts must be added in the <AdVerifications> tag at <Ad> tag level. Verification scripts under the <Extension type="AdVerifications"> tags will be used only as a fallback if no <AdVerifications> tag is found at <Ad> tag level.

Please note: VPAID is not supported by OMSDK cf. IAB FAQ OM SDK compliance
