-WhatsApp's UGC transparency is assessed through the [Meta Content Library](https://transparency.meta.com/researchtools/meta-content-library/) as a single global resource applied across Brazil, the EU, and the UK, while advertising transparency draws on the [Meta Ad Library API](https://www.facebook.com/ads/library/api/) — which serves ads across Meta platforms — with region-specific access regimes across the same three regions. Neither WhatsApp nor the Meta Content Library provides any API or interface enabling programmatic access to public user-generated content, placing the platform in the Not Available band for UGC. For advertising, the Meta Ad Library provides full programmatic access to all ad types in the EU and UK, while Brazil is restricted to political and issue ads. Across all regions, the library provides free access, keyword and advertiser-ID search, standardized timestamps, and a maintained changelog, but lacks engagement data, complete targeting criteria disclosure, sufficient spending granularity, and specific rate-limit documentation.
+WhatsApp’s UGC data transparency is assessed through the [Meta Content Library](https://transparency.meta.com/researchtools/meta-content-library/) as a single global resource applied across Brazil, the EU, and the UK, while advertising transparency draws on the [Meta Ad Library](https://www.facebook.com/ads/library), with region-specific access regimes. Neither WhatsApp nor the Meta Content Library provides any API or interface enabling programmatic access to public user-generated content, placing the platform in the Not Available band for UGC. Advertising transparency varies by region: the Meta Ad Library in the EU and the UK systematically covers all ad types served over the past year, though the UK version differs from the EU in that its GUI enables structured data extraction for ads labeled as political and “social issue” ads, which are banned in the EU. In Brazil, the tool is largely limited to ads labeled as political and “social issue” ads, as other ads can only be viewed while actively running and cannot be systematically extracted. Across all regions, the library provides free access, unique advertiser identifiers, and ad delivery periods, but lacks engagement metrics, granular spending data, complete targeting criteria, and specific rate-limit documentation, with the availability of such information varying by ad type.
