Meta updates transparency requirements for ad-buying solutions
Meta has updated its developer policies covering separate ad accounts and transparency for ad-buying solutions, with the transparency provisions taking effect on 3 February 2027. The updated Separate Ad Accounts policy continues to require that end advertisers be kept in distinct ad accounts, with an exception: ad-buying solutions implementing vendor_id and/or brand fields in their Product Catalogue and/or Pixel and CAPI integrations are exempt from the separate-account requirement, provided the fields are properly implemented, and other terms are met.

What changed
The Transparency provision moves to a reactive disclosure model. Ad-buying solutions must, upon the end advertiser's request, disclose the amount spent on Meta advertising on the advertiser's behalf: separate from fees: and the campaign configuration, settings, and post-campaign reporting using Meta terminology. Meta will not proactively provide this information unless required by law or unless a policy violation is identified.
Why it matters for advertisers
For you, this means agencies and ad-buying platforms operating consolidated client accounts must plan a 2026 review of vendor_id and brand field implementation, and prepare disclosure templates for the reactive transparency requirement. Particularly relevant for white-label and managed-service offerings, where end advertisers may not currently have visibility into platform-level reporting.
