How to update a product feed for Perplexity shopping comes down to one question: which system does Perplexity read your catalog from? We found no public Perplexity screen where a merchant uploads a file or edits a price. The change is made upstream, in a feed you send to PayPal, in your Shopify or BigCommerce admin, or on the product page Perplexity's crawlers read, and it travels from there. One route has a documented refresh schedule, because PayPal says it downloads feeds once daily by default. For the last hop into Perplexity's product cards, we found no published sync time on any page we read on October 7, 2026.
Which system does Perplexity read your catalog from?
Five entry points appear in the vendors' own pages, and each puts the edit in a different place.
| Route | Where you change a price or stock level | What the owner documents about refresh | No published figure that we found |
|---|---|---|---|
| Perplexity Merchant Program | In the product data you share once Perplexity answers the signup form | Access to "live details", no interval given | Feed format, upload method, refresh time |
| PayPal Store Sync | In the feed file PayPal fetches | Feeds downloaded once daily by default | Time from Store Sync to a Perplexity product card |
| Shopify | In the Shopify admin | Shopify Catalog "continuously updates" product data | An interval, or a Perplexity entry in the Help Center channel list |
| BigCommerce | In BigCommerce, connected through the PayPal Store Sync app | Catalog, inventory and orders connect through the app | A sync interval |
| Open-web crawl | On the product page | Up to 24 hours for robots.txt changes | A recrawl schedule, or whether crawled prices reach product cards |
The launch post from Perplexity, dated November 18, 2024, introduced the Merchant Program "to make it easy for large retailers to share their product specs with us, ensuring we can access live details on all the best available products." It calls the program free, lists a custom dashboard for search and shopping trend insights among the benefits, and points interested retailers to a signup form. The same post says the discovery experience is "powered by platform integrations including Shopify".
PayPal is the second route. A November 25, 2025 press release from PayPal says store sync "makes merchant product catalogs instantly discoverable within Perplexity's results", and PayPal's developer documentation is where the feed format and the refresh schedule are written down.
Where do you change a price so Perplexity shows it?
To update product prices in Perplexity, change the price in the system that feeds it and let that system's next sync carry the new number. On Shopify or BigCommerce that is the product record in the admin, and on PayPal Store Sync it is the feed file.
The catalog page from PayPal, last updated September 2, 2026, lists CSV, TSV and pipe-separated files as supported formats, in three specifications: the Google Product Feed, the OpenAI ACP Product Feed, and the PayPal Enhanced Shopping Feed, which adds is_eligible_search and is_eligible_checkout to the Google fields. Price is written with its currency code, as in "19.99 USD". A discount goes in sale_price, and availability takes one of four exact values: in_stock, out_of_stock, preorder or backorder.
Two details on that page matter on the day you reprice. PayPal says the variant ID is used for deduplication and product updates, so keep it stable when only the price changes. The page also says rows "with missing required fields or malformed values are skipped during ingestion without failing the entire feed." By that rule, a badly formatted price can cost you the row for that cycle while the rest of the file goes through.
Depth of product data has a ranking side as well. A Help Center article from Perplexity, last modified September 3, 2026, says its answer engine "is more likely to recommend merchants who provide deeper product details such as availability, reviews, pricing, and specifications." The same article sends shoppers who have questions about prices or availability to "the brand or retailer directly", so a stale price on a card becomes your support ticket.
Is there a Perplexity merchant center with a feed upload, and what do Shopify and BigCommerce stores do?
A Perplexity merchant center with a feed upload screen is something we found no public documentation for, and Shopify or BigCommerce stores pass product data through their platform instead. What exists publicly is the Merchant Program signup form from the 2024 post. When we requested perplexity.ai/merchants on October 7, 2026, it redirected to a sign-up page for Perplexity Computer, an AI agent pitched at ecommerce operators, and nothing on that page mentions product feeds.
For Shopify, the Help Center page from Shopify says "Shopify Catalog continuously updates your product data, ensuring that there's accurate inventory and pricing across every AI channel." The channels that page names are ChatGPT, Microsoft Copilot, Google AI Mode and Gemini, and Meta. An April 2, 2026 post on the company blog from Shopify adds that Shopify Catalog "automatically syndicates your product data to connected AI platforms, including Perplexity, ChatGPT, and Google AI Mode", and says in another passage that "Perplexity requires joining its Merchant Program." The post leaves those two statements unreconciled. Our reading for a Shopify merchant: edit prices in the admin, and treat the Merchant Program form as a separate application.
The documented BigCommerce path runs through PayPal. Commerce, the parent company of BigCommerce, announced on April 29, 2026 that PayPal's Store Sync is integrated in the BigCommerce App Marketplace and Channel Manager, connecting product catalogs, inventory and order management to AI surfaces "including Microsoft Copilot, Meta and Perplexity." The release gives no sync interval, so confirm in the app listing what your plan can install. Merchants who integrate with PayPal directly need approval first: the catalog page says Store Sync access is requested through a PayPal account manager or the PayPal AI team.
How long does a change take to show up?
The Perplexity merchant center sync delay has no published number that we could find, though one upstream leg has a documented cadence. The feed connection page from PayPal, last updated June 4, 2026, states: "By default, PayPal downloads feeds once daily." It adds that updated availability, pricing and listings "become active in Store Sync after the next successful ingestion cycle completes", and that a different cadence is arranged through your PayPal account manager.
A daily cycle is slower than the press release's "instantly discoverable" implies, and it ends at Store Sync. For how quickly Perplexity reflects a Store Sync update, a Shopify Catalog update or a Merchant Program update, we found no figure on any of these pages.
The crawl route has its own clock. The crawler documentation from Perplexity says of its robots.txt settings that "it may take up to 24 hours for our systems to reflect changes." It describes PerplexityBot, which surfaces and links websites in search results, and Perplexity-User, which may visit a page when a user asks a question. We found no statement there about how often a product page is fetched again, or whether a crawled price reaches a product card.
In the hypothetical timeline below, every clock time is our assumption: the store rebuilds its feed file once a day at 02:00, and PayPal's daily download runs at 06:00.
| Price edited in the store | Lands in the feed file | Picked up by the download | Wait before ingestion starts |
|---|---|---|---|
| Monday 09:00 | Tuesday 02:00 | Tuesday 06:00 | 21 hours |
| Monday 01:30 | Monday 02:00 | Monday 06:00 | 4.5 hours |
| Monday 02:05 | Tuesday 02:00 | Tuesday 06:00 | about 28 hours |
Under those assumptions the same edit waits from just over 4 hours to just under 28 hours before PayPal starts processing it, and the Perplexity leg comes after that. Ask your account manager when the download runs, schedule the export to finish shortly before it, and plan promotions a day ahead instead of repricing by the hour.
How do you confirm that a price change has gone through?
Work down the chain from your own systems to the product card, and log the variant ID, the old and new price and the time at each step.
- Open the feed file at the exact URL or path PayPal reads and find the row. The price should be in the "19.99 USD" form with the ID unchanged. PayPal's troubleshooting table names a changed file path or filename as the cause when a file downloads but the catalog does not update.
- Ask for the last successful ingestion time. PayPal's page says the account manager confirms when ingestion is active, and we found no self-serve ingestion log described on the pages we read. On Shopify or BigCommerce, check the channel or app for sync errors.
- Check the live product page. The visible price and the Product structured data should match the feed, the same agree-with-yourself discipline behind our entity consistency audit. In your server logs, look for PerplexityBot and Perplexity-User requests to that URL after the edit, checked against the IP ranges Perplexity publishes. Our guide to getting cited by ChatGPT, Perplexity and AI Overviews covers crawler access.
- Ask Perplexity from a US account, since the Help Center describes Instant Buy as "currently available to all users in the United States." It adds that this does not apply to Enterprise Pro or Enterprise Max plans. Name the product precisely, open its card, read the price there, and repeat the next day. Answers vary between runs, a limit we describe in where prompt-based tracking breaks, so screenshot the card with the time.
- If the product carries Instant Buy, place a small test order. For Store Sync merchants, the integration page from PayPal has your own cart API report "Price changes during checkout" as a validation issue, and it lists accepting a price increase as an action that needs the customer. We found no Perplexity page on how its card handles that, so the order total in your own system settles it for your setup.
What this means for how you run pricing
Perplexity sits downstream of systems you already operate. The record to maintain is the one in your commerce platform, with the feed and the product page kept as faithful copies on a daily cycle.
Confirming a price is also a different job from knowing how often assistants recommend you in the first place, which is what AI share of voice measures. For further resources, see our AI visibility checker and our AI search optimization service. Until Perplexity publishes a refresh interval, the only number you can plan around is the upstream one, and it is worth asking your PayPal or platform contact to put it in writing.
