AP2 Human-Not-Present Transaction Flow

Before writing code

Fetch live docs:

1. Fetch https://ap2-protocol.org/specification/ for the human-not-present flow specification
2. Web-search site:github.com google-agentic-commerce AP2 human-not-present intent mandate for samples
3. Fetch https://ap2-protocol.org/topics/core-concepts/ for flow overview
4. Fetch https://ap2-protocol.org/roadmap/ and the latest spec to confirm the current support level for human-not-present (Intent Mandate) flows in the version you're targeting

Conceptual Architecture

What Human-Not-Present Means

In a human-not-present flow, the user provides authorization upfront and then leaves. The Shopping Agent acts autonomously within the constraints defined in the signed Intent Mandate.

Spec Status

Human-not-present is a first-class flow in current AP2 releases (added as the spec evolved beyond the initial human-present-only V0.1). Always verify the exact Intent Mandate fields and required signing semantics against the version you're targeting — fetch the live spec before implementing.
