How to cross-post to platforms?
Cross-post takes a listing you already have and republishes it on another connected marketplace, so you don't retype the same product into every seller centre.
Cross-posting takes a listing you already have on one platform and republishes it on another connected shop. Instead of retyping the same product into every seller centre, OneCart carries the title, description, images, price and variants across for you.
Before you start
- You need at least two connected shops — one to copy from, one to copy to. See how to connect a platform if you only have one.
- The source listing needs images already loaded in OneCart. Some platforms reject listings under a minimum image count (Shopee needs at least 3). See how do I add images to products.
- On a free trial, the first 10 cross-posted listings are included. After that you’ll be asked to upgrade before you can continue.
Which method should I use?
| Use this when | |
|---|---|
| Bulk cross-post | You’re moving more than a handful of listings. OneCart AI can fill in the category and required attributes for each listing, and you review everything before it publishes. |
| Single listing (below) | You want full manual control over one specific product. |
Most sellers should start with the bulk cross-post — it handles one listing just as well as a hundred, and the AI step saves you filling in category attributes by hand.
Cross-post a single listing
From the OneCart left-hand menu, go to E-commerce Listings → Manage Listings → View Matched Listings (app.getonecart.com/listings).
Search for the listing you want to cross-post.
Open the listing and click Cross Post Options.
Pick the shop you want to cross-post to. If you have a lot of shops connected, use the search box at the top of the dropdown to filter them. Only shops that can receive this listing are shown — if the list is empty, you have no other connected shop that accepts it.
The listing form opens pre-filled from your source listing. Fill in anything the destination platform requires — category, brand and any mandatory attributes.
Look for the ⚡ icons on the form: these are the AI helpers. They can enhance the title and description, or autofill blank fields for you. Click any ⚡ to try it.
Check everything, then click Create Listing.
Where the listings go
Once published, the new listing appears in your destination seller centre and gets imported back into OneCart, where it’s matched to the same SKU as the source. That’s what keeps stock in sync across both platforms afterwards.
Troubleshooting
- Shopee errors (invalid logistic info, not enough images) — see Shopee cross-post errors.
- A listing failed with a category or attribute error — the destination platform rejected a required field. Bulk cross-post surfaces these on the review page where you can fix and retry; see bulk cross-post.
- You’re being asked to upgrade — trial accounts include 10 cross-posted listings.
