⚠️ **IMPORTANT** ⚠️
The legacy Direct Sales endpoints for Advertisers, Campaigns, Orders, Advertisements and Geos are being replaced with new v2 endpoints with enhanced functionality. ### Timeline
**Phase 1: Before April 15, 2026**

- Continue using existing Direct Sales API endpoints
**Phase 2: April 15, 2026 10:00:00 AM EST - July 14, 2026 11:59:59 UTC (Migration Period)**
- **v2 endpoints become available**
- Legacy endpoints continue to work during this period
- Both legacy and v2 endpoints are operational
- **We strongly encourage you to start testing and migrating to v2 endpoints as soon as they become available to ensure a smooth transition before the sunset date and to continue ad delivery without disruption.**
**Phase 3: After July 14, 2026 11:59:59 UTC**
- Legacy endpoints are **removed and will stop working**
- Only v2 endpoints will be supported
- [Old] Standard campaigns can use v2 GET endpoints
