OWOX BI processes and imports to Google Analytics these dynamic parameters in the VK ad links:

• {ad_id} — advertisement ID
• {campaign_id} — ad campaign ID

However, VK doesn't provide data on some dynamic parameters via their API. Due to that, OWOX BI does not process these parameters:

• {random} — a random number
• {campaign_name} — a campaign name set in VK (for ads with buttons and carousel ads only)
• {platform} — a user's platform (for ads with buttons and carousel ads only)
• {price_list_id}, {product_id} — parameters for the dynamic targeting tags

If you use some of those unsupported parameters in UTM-tags, you’ll see the parameter names instead of their values. For example, {campaign_name} instead of the actual campaign name.

In order to keep matching visits and ad expenses in the Cost Analysis report, move the unsupported parameters from UTM-tags to additional custom GET-parameters and collect them to custom dimensions in Google Analytics:

• Cost data will be available only for UTM-tags values
• Session data will be available for unsupported parameters (through custom dimensions) and UTM-tags values
