Implement the ACP delegated payment flow and SharedPaymentToken (SPT) provisioning. Use when integrating with Stripe for payment tokenization, handling SPT lifecycle, or building the payment completion flow.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ACP Delegated Payment & SharedPaymentToken
## Before writing code
**Fetch live docs**:
1. Fetch `https://developers.openai.com/commerce/specs/payment/` for the delegated payment specification
2. Fetch `https://docs.stripe.com/agentic-commerce/concepts/shared-payment-tokens` for SPT implementation details
3. Web-search `site:docs.stripe.com agentic-commerce delegate payment` for Stripe integration guide
4. Web-search `site:github.com agentic-commerce-protocol spec openapi delegate` for the delegate payment OpenAPI spec
## Conceptual Architecture
### What Delegated Payment Solves
The agent facilitates purchases but must **never see raw card data**. Delegated payment creates a secure intermediary:
- Buyer's payment credentials go to the PSP (Stripe), not the agent or merchant
- PSP returns a single-use, scoped token (SPT)
- Agent passes the SPT to the merchant in the `complete` call
- Merchant charges via PSP using the SPT
### End-to-End Flow
```
Buyer → Agent: "Buy this"
Agent → PSP: POST /agentic_commerce/delegate_payment (credentials + constraints)
PSP → Agent: SharedPaymentToken (single-use, scoped)
Agent → Merchant: POST /checkout_sessions/{id}/complete (with SPT)

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/acp-delegated-payment@sha256:941f624d0f0b5dd0The line at the top of this page pins the label git:20260309.786511c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
