PayPal Agentic Commerce with Highstreet.io: make your catalog discoverable and shoppable by AI assistants
Shoppers are starting to buy through AI assistants. With Highstreet.io's PayPal Agentic Commerce integration, your products can be found, recommended and purchased inside ChatGPT and Google AI Mode — powered by your product feed: the one we already manage for you, or the one we can set up.
What PayPal Agentic Commerce integration is — and what Highstreet.io handles
PayPal Agentic Commerce lets merchants make their catalog available to AI shopping assistants, so that when a shopper asks an assistant to find a product, your items can appear, with accurate price and availability, and be purchased. It relies on two building blocks — Store Sync (discoverability) and Agent Ready (in-assistant checkout).
The discoverability layer runs on your product feed — and that is exactly what Highstreet.io already manages. As PayPal notes, Store Sync integrations depend on whoever manages your product feed. That's Highstreet.io: we format, deliver and keep your feed in sync, so activating Store Sync is a configuration step, not a project.
Store Sync: your product feed, synced for ChatGPT and Google AI Mode
Store Sync makes your catalog discoverable to AI agents. Highstreet.io handles the feed end to end:
Feed formatting in the required structure (Google Shopping format plus the ChatGPT-specific fields)
Secure delivery via SFTP to PayPal
Daily automatic updates, so assistants always see correct prices, current availability and new products
Product variants (size, color and so on) handled correctly
One connection through Highstreet.io reaches multiple AI surfaces: ChatGPT (via the OpenAI Agentic Commerce Protocol) and Google AI Mode / Gemini (via Google's Universal Commerce Protocol) — plus future PayPal AI partners.
If you already use Highstreet.io to manage your feeds, you are most of the way there: activation requires minimal configuration on top of what you already have.
Agent Ready: checkout inside the AI (what the merchant needs)
Store Sync makes you discoverable; Agent Ready makes you shoppable — enabling the customer to complete the purchase without leaving the assistant. Agent Ready lets Braintree (PayPal's enterprise payment gateway) merchants accept payments from AI assistants (ChatGPT, Google AI Mode, Gemini) with PayPal's fraud detection, buyer protection and dispute resolution.
Where the work sits:
Highstreet.io delivers and maintains the product feed (the prerequisite for everything).
The merchant implements the checkout logic — the Cart API endpoints (create cart, update cart, checkout) — and the payment via PayPal Orders v2 or Braintree.
Highstreet.io can support you during the evaluation of Agent Ready, so you can decide whether and when the in-assistant checkout is worth the additional development.
Why activation is immediate with Highstreet.io
The hard part of agentic commerce for most merchants is the catalog. According to PayPal's Agentic Commerce Pulse Report (a survey of 498 US merchants, February–March 2026), nearly all merchants report at least partial visibility into AI-agent traffic, yet only about one in five have 80% or more of their catalog available as structured, machine-readable data.
If Highstreet.io already manages your feed, that gap is already closed — your catalog is structured, enriched and updated daily, which is precisely what AI assistants need.
One feed, multiple AI surfaces — no separate integration per platform
Daily sync — prices and availability always current for the assistants
Full control over brand, prices and communication
Products surfaced by relevance, not by ad position
