Data, retrieval, actions, identity, and operating limits
A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
Read campaign structure, delivery state, recommendations, conversion configuration, and performance reports across authorized accounts.
03 · Actions and write paths
Create and update campaigns, ads, keywords, audiences, budgets, conversion objects, and bulk entities; submit and retrieve reports.

- Microsoft Advertising + analytics or warehouse + creative-production platform: cross-system decision workspace
Evidence and dates
First-party references, with publisher and review dates separated
“Publisher updated” is shown only when the page exposes an update date. “BYO-UI reviewed” records when this research checked the reference. A missing publisher date is reported as missing—not replaced with the review date.
