What is ChatGPT Instant Checkout?

ChatGPT Instant Checkout is a purchase flow inside ChatGPT.

As shoppers describe what they need during the conversation, ChatGPT recommends the most relevant products from your catalog, and customers select and pay right there — no redirects.

What Instant Checkout
needs to run

1

Clean, structured product data

A catalog the assistant can reliably interpret: products, variants, attributes, pricing, availability, and eligibility rules.

2

Predictable checkout and order endpoints (ACP)

Endpoints that let the assistant create a checkout session, calculate shipping and taxes, confirm the final total, and create the order.

3

Post-purchase status and tracking updates

A consistent update loop so the buyer sees order progress in chat: confirmations, status changes, shipments, and tracking.

Why teams get stuck after “we integrated”

Instant Checkout is strict about data quality and API behavior. Small issues quickly turn into real problems:
  • malformed fields
  • totals that don’t match
  • slow responses
  • inventory mismatches
  • retries that create duplicates
  • tracking that never shows up in chat
The hard part is reliability at scale — across real orders, edge cases, and spec updates. A working store is only part of the job.

Choose your integration model

SellerAI as MoR

Merchant of Record

The buyer pays SellerAI. SellerAI handles payment capture and the Instant Checkout payment flow, then pays out to you. You control fulfillment: inventory, shipping, and order execution.

You stay MoR

Direct integration

The buyer pays you through your existing payment stack. You remain a Merchant of Record.

SellerAI provides the agentic commerce layer (feed + ACP endpoints + updates) so your team doesn’t have to build and maintain the protocol surface from scratch.

Go-live checks that
prevent production issues

Before launch, teams typically validate:

Product data completeness (variants, attributes, policies, eligibility)

Response speed and error handling (timeouts, retries, duplicate prevention)

Shipping and taxes behavior (especially when buyer inputs change)

“Final total” rules and confirmation semantics

Order status mapping and tracking updates end-to-end
