The result is not an uploaded file, but working listings built for the Romanian customer. ## Adding a product means designing a data structure - Adding a product is not about pasting in a description. It means designing **a correct data structure** that will pass Trendyol's review and make sense to a Romanian customer. - Before a listing can be created, the brand, the lowest category level, the attributes and their allowed values all have to be linked correctly. Once submitted, the product enters an approval process, and rejected listings stay unpublished until the errors are fixed. - Some data on an approved product - the brand, the category, certain variant attributes - cannot simply be changed later. That is why we make the key decisions before publication, not after it. ## A product on Trendyol is more than a description ### Data structure The category, brand, product code, variants and attributes have to add up to a technically valid whole. ### The language of the market The title and description should read naturally to a Romanian customer, not like a mechanical translation of your original product page. ### Product presentation Photos, the order of information and the way benefits are framed answer the questions a customer has before buying. ### The commercial layer Price, stock, VAT, delivery time and variants have to match how orders are actually fulfilled. Trendyol requires the lowest category level and data that matches the current attribute list. The platform recommends pulling the current structure regularly, because categories and their parameters can change. ## Before we start, we assess how ready your catalogue is We do not expect a perfectly prepared file. We begin by reviewing your materials, pointing out the gaps and agreeing which data we will fill in ourselves and which needs confirmation on your side. - completeness of identification data - availability of EAN codes or other identifiers - quality of product photos - completeness of parameters and attributes - correctness of the variant structure - whether a category can be assigned - availability of material for translation - consistency of information across files Sellers often do not know whether their export from **WooCommerce**, **BaseLinker**, an ERP system or **eMAG** is usable at all. We check that before any work starts. ## Trendyol Product Passport For every SKU we create a structured record that takes the product from raw material to a live listing - and stays with you as the base for future updates. Technically it is a well-organised master sheet. The name "Product Passport" captures its role: one complete set of data per product, from identification to publication status. ## Product Passport - what it covers for every SKU - product and brand identification - assigned category (lowest level) - mandatory and optional attributes - variant structure - Romanian title and description - photo set and photo order - pricing, tax and logistics data - publication status - reason for rejection, if any ## From raw data to a live listing ### Product selection We decide which products are worth launching first. Starting with the whole catalogue does not always pay off. ### Materials audit We check the data, photos, identifiers, variants and documentation. We put together a list of gaps to fill. ### Catalogue mapping We match your products to the categories, brands, attributes and values available on Trendyol. ### Content localisation We write Romanian titles and descriptions, tidy up variant names and adapt the messaging to the local customer. ### Building the product pages We bring technical data, content, photos, prices, variants and logistics information together into complete listings. ### Publication and approval checks We submit the products, monitor their statuses and analyse the reasons behind any rejections. ### Fixes and catalogue handover We clear the errors found, resubmit the products for review and prepare a summary of the live listings. **A submitted product is not a published product yet.** The approval process starts once the data is sent, and products that are pending or rejected do not go on sale. ## What makes a product page good Trendyol's international API documentation covers, among other things, the title, description, brand, category, photos, price, stock, VAT, delivery time and attributes. Variants are built on a shared model identifier and on the category parameters flagged for that purpose. ### A title that identifies the product It carries the key information without artificially repeating words. ### The right category It decides which parameters are available and how the product is classified. ### Complete attributes They describe the product unambiguously and help the customer compare variants. ### A natural Romanian description It explains the use case, the benefits, the key features and what the set contains. ### Logical variants Colours, sizes and other versions grouped in line with the structure of the given category. ### Photos in the right order The first photo identifies the product, the rest answer buying questions. ## From input materials to a finished listing ## Input materials - an export from a system - an untranslated description - inconsistent colour names - some parameters missing - photos in random order - variants saved as separate products ## A finished Trendyol listing - category and brand assigned - parameters tidied up - natural Romanian language - a logical variant structure - a prepared photo set - publication status verified ## The most common publication blockers ### The wrong category A product cannot be submitted to a category that still has subcategories beneath it. ### Missing attributes Every category can have its own set of required parameters and values. ### Badly built variants Products split apart or merge incorrectly when the identifiers and variant parameters are inconsistent. ### Brand not in the system The brand has to be found on the Trendyol list or put through the process of adding it. ### Inconsistent data Differences between the title, parameters, description and photos make both the review and the buying decision harder. ### No status tracking Simply submitting the products is no guarantee that all of them were accepted. Trendyol provides a separate process for adding a brand, requires up-to-date category and attribute mapping, and lets you read the reasons why product processing failed. ## What you get once the rollout is done - **A clean master catalogue** - a consistent product data base to use for every future update. - **Romanian product content** - titles, descriptions and variant names matched to the products and the local market. - **Category and attribute mapping** - every product with the right category and the required set of parameters. - **Finished product pages** - content, data, photos, variants and commercial information in complete listings. - **A publication report** - which products were accepted, which need action and why. - **A base ready to grow** - a structure to reuse when adding new products and opening further markets. ## A catalogue is not a one-off project - new products and variants appear - prices and availability change - the platform keeps developing its category structure - new attributes can show up - content needs improving based on results - products can need updating or another round of review Our approach A well-prepared catalogue makes updates, integration and expansion into new markets easier. That is why we build a structure that can grow, instead of starting from scratch every time. Trendyol's category tree and attribute values can change, so we work from current data before any update. ## Frequently asked questions # Powiązane - [Pytania i odpowiedzi](/en/faq/trendyol-product-listing.md) - [Trendyol profitability calculator - margin](/en/computations/trendyol-profitability-calculator.md) # Wersje językowe - [PL](/pl/services/trendyol-dodawanie-produktow.md) - [RO](/ro/services/adaugare-produse-trendyol.md)
