Rejected outright (not a warning) when it would violate a campaign invariant: currency (a product's replacement pricing option settles in a different currency than this buy), budget headroom (the update would exceed the campaign's remaining all-in budget), or mode compatibility (the campaign is directed and has no platform-managed update path). A flight date outside the campaign's current window is not a failure — the campaign flight is widened to cover it and a warning is returned. ## OpenAPI ````yaml /v2/buyer-api-v2.yaml patch /media-buys/{mediaBuyId} openapi: 3.0.0 info: title: Scope3 Buyer API version: 2.0.0 description: |- REST API for advertisers to manage advertisers, campaigns, and reporting. ## Authentication All endpoints require a Bearer token in the Authorization header: ``` Authorization: Bearer your-api-key ``` ## Base URL `https://api.interchange.io/api/v2/buyer` ## For AI Agents AI agents can use the MCP endpoint at `/mcp/v2/buyer` with three tools: - `initialize`: Start an MCP session - `api_call`: Make REST API calls - `ask_about_capability`: Learn about API features servers: - url: https://api.interchange.io/api/v2/buyer description: Production server security: [] tags: - name: Account description: Account management, service tokens, and preferences - name: Advertisers description: Manage advertisers - name: Product Discovery description: Discover and select products - name: Campaigns description: Manage advertising campaigns - name: Creatives description: Build, manage, and sync campaign creatives via AdCP Creative Protocol - name: Reporting description: Access performance metrics - name: Event Sources description: >- Manage event source configurations and log conversion/marketing events for attribution - name: Property Lists description: Validate property lists against AAO registry - name: Sales Agents description: View and connect sales agents - name: Measurement description: Measurement sources, records, context, and freshness - name: Syndication description: Syndicate resources to ADCP agents - name: Tasks description: Track async operation status - name: Buyer Billing description: >- Consolidated invoicing for buyers — invoices and pending invoice items issued by Scope3 across the buyer customer. - name: MCP description: Model Context Protocol endpoints for AI agents paths: /media-buys/{mediaBuyId}: patch: tags: - Campaigns summary: Update media buy description: >- Partially update a single media buy, resolved top-level by mediaBuyId — the owning campaign is resolved server-side, consistent with GET /media-buys/{mediaBuyId}.
