  2. When using a VAST XML, the maximum data size is decided by the external partner responsible for generating it.
  3. For external monitoring of impressions, it is necessary to separately provide a URL for 1×1 px monitoring image (this URL must not be a part of the VAST XML file). If the monitoring image is included in the VAST, it measures the start of video playback, not the impression.
