VCAP-AP2 Binding
If the AP2 Protocol is how agents agree and initiate payment intent, this binding is how those intents acquire concrete escrow and capture rules under VCAP — without hand-waving the gaps.
Definition
What it is
An open specification (draft) that bridges AP2 flows to VCAP escrow, release conditions, and capture behavior.
Who it's for
Implementers wiring marketplace negotiation to settlement backends.
When to use
- You implement AP2 and need precise settlement mapping
- You are debugging mismatches between negotiation states and escrow states
- You want one chartable path from “accepted” to “funds released”
Numbers and limits
- Problem solved
- Keeps AP2 and VCAP aligned so releases are predictable
- Typical flow
- Intent → hold → verified delivery → capture
- Spec pairing
- Read alongside VCAP + AP2 product docs
