Microsoft Advertising (Bing) Integration — Phase 1 (Read-Only)

Connect Microsoft Advertising accounts via Bing Ads API. Import Search, Shopping, Audience, and Performance Max campaigns with full metrics (impressions, clicks, conversions, CPA, ROAS). Unified cross-platform reporting.

Key technical notes:

• Microsoft Advertising API v13 — OAuth2 with Microsoft Identity Platform
• Entity hierarchy: Customer → Account → Campaign → Ad Group → Ad
• Shared budgets, UET tags (conversion tracking), audience lists
• Reporting API with async report download

Impact: Microsoft Search Network covers 36% of US desktop searches. Many Google Ads campaigns are mirrored on Bing — agencies need both in one view.
