AdCP Python SDK 8.0.0-beta.2

SDK 8 beta release notes are cumulative. If you are upgrading from SDK 7.x, read both migration guides before deploying:

Breaking changes inherited from beta.1

  • ADCPClient.handle_webhook() no longer accepts unsigned MCP callbacks by default. Configure webhook_secret for the legacy HMAC path, or use WebhookReceiver for RFC 9421 verification and delivery deduplication.
  • allow_unauthenticated_webhooks=True is a temporary compatibility escape hatch only for endpoints isolated from untrusted networks; multi-agent clients must scope it by agent ID.
  • SDK 8 aligns its safety and asset APIs with JavaScript SDK v13, including the public AssetInstance discriminated union and stable Python *Content variant names.

See beta.1 / PR #1032 for the complete breaking-change rationale.

Added in beta.2

  • Bundles AdCP 3.2.0-beta.0 schemas and exposes the compact lifecycle across the client, multi-client, MCP, A2A, server handlers/builders, decisioning framework, and CLI:
    • list_products
    • request_proposals
    • refine_proposals
    • decline_proposals
    • buy_products
    • accept_proposal
    • control_media_buy
  • Adds report_plan_adjustment and sync_agent_notification_configs.
  • Adds compatibility coverage for 3.0 legacy, 3.1 legacy, 3.2 legacy lifecycle, 3.2 direct purchase, and 3.2 proposal purchase.
  • Implements the strict AdCP 3.2 RFC 9421 signing profile. A 3.0/3.1 peer currently requires SigningConfig(signing_profile_version="3.1"); see the migration guide.

Proposal support boundary

Beta.2 provides the typed lifecycle primitives and transport/server dispatch needed to list products, request/refine/decline proposals, buy directly, accept a proposal, and control a media buy.

The richer negotiation layer—capability-aware builders, constraint and lineage verification, digest checking, batch preflight/rollback helpers, and complete buyer/seller orchestration examples—remains tracked in #1023. Do not interpret the beta.2 lifecycle primitives as completion of that higher-level validation framework.
