oopbuy links: how to turn a Taobao or Weidian URL into something an agent can buy
This is the least glamorous page on the site and the one that saves the most money. Most “my agent can’t find the item” tickets are a link problem, not an agent problem: a mobile share URL, a shortened redirect, or a link to a shop instead of a product.
Anatomy
What a working product link looks like
A marketplace product URL carries an identifier. On Taobao it is usually an id= parameter; on Weidian the product number sits in the path; on 1688 it is an offer/ segment. If the URL you copied has none of those, it is probably a shop page, a search page or a share redirect.
Share links are the common failure. When you tap “share” in a Chinese marketplace app, you often get a short URL that resolves through a redirect chain, and some agents will not follow the chain. Open the link in a browser first, let it settle on the real product page, then copy that address.
The test is simple: paste the link into a private browser window with no account signed in. If it shows the product with a price, it will work. If it asks you to log in or bounces to a homepage, it will not.
Convert
Four steps, in order
- 1
Open it in a normal browser
Not the app. Let every redirect finish. What you want is the address bar at the end, not the one you started with. - 2
Check for an identifier
id=, offer/, or a numeric path segment. No identifier means no product, which means no order. - 3
Strip the tracking parameters
Anything after the identifier that starts with utm_, spm_, share or from can go. They do not break the link, but they make it long and they leak your session. - 4
Paste it into the agent’s link box
Then check that the agent preview shows the same title and a similar price. A mismatch means the agent resolved something else.
Our links
What our ref parameter does
Plainly, because it is your click.
Every outbound link on this site ends in ?ref=oopbuy.sbs. That parameter tells the partner which page sent you. It does not change the price you see, it does not create an account for you, and it does not follow you around the web.
If you arrive without it — because you typed the address yourself, or a browser extension stripped it — nothing breaks. The catalogue works exactly the same way. The parameter exists so we can see which of our pages are useful, which is the only feedback we get.
| Case | What happens |
|---|---|
| Normal click | ref=oopbuy.sbs is appended, page opens in a new tab |
| You strip the parameter | Page still works; we simply cannot attribute the visit |
| You copy the link into a chat app | Some apps shorten and drop the parameter; again, nothing breaks |
| You land on a category or search page | Same rule — ref is appended to whatever path you were sent to |
Common questions
Link questions
Do I need an account to browse the catalogue?
No. Browsing the partner catalogue does not require a login. You only need an account when you actually place an order.
My link works but the agent says the item is unavailable
That is a stock problem, not a link problem. Chinese marketplace sellers delist constantly and a row can die between the catalogue snapshot and your order.
Does the ref parameter cost me anything?
No. It is an attribution tag. The price you pay is the price on the listing plus the agent’s published fees.
