AI Assistant for Your Trendyol Store: Answering Questions, Catalog and Orders

An AI assistant for Trendyol sellers does two jobs: it answers the customer questions on your Trendyol listings within the rules and before the deadline, and it carries your Trendyol catalog and orders into your assistant on WhatsApp, Instagram and web chat. Türkiye's e-commerce volume grew 52.2% in 2025 to 4 trillion 567 billion lira (Ministry of Trade, May 2026), and speed decides who gets the sale: in Entagl's Response Velocity Study of 32,581 conversations, replies within 60 seconds converted at 35.1%, versus 7.1% for replies that took 1 to 24 hours. One limit up front: Trendyol has no one-to-one messaging with buyers. No AI assistant can DM a Trendyol customer.

Trendyol's own seller portal speaks of more than 300,000 sellers and 31 million Trendyol customers (Trendyol Seller Panel, as of September 2026). At that scale every unanswered question is a lost sale: in PowerReviews' 2021 analysis of 1.5 million product pages across more than 1,200 brand and retailer sites, visitors who interacted with Q&A content converted at a rate 194.2% higher than those who did not (PowerReviews, 2022).

This article covers Trendyol's customer-question rules, how AI answers those questions, how catalog and order data flows into a WhatsApp assistant, and what the Trendyol platform does not allow. The examples come from Entagl's Trendyol integration; the principles apply to every seller.

What can an AI assistant do on Trendyol, and what can it not?

Trendyol gives sellers an official API (developers.trendyol.com). What is and is not possible through it is clear:

Task	Possible?	How
Answering customer questions	Yes	Waiting questions are pulled through the API and the answer is published
Reading the product catalog (price, stock, images, product link)	Yes	Approved products are synced on a schedule
Tracking order status	Yes	Shipment packages arrive by instant notification (webhook) and periodic polling
Recommending Trendyol products on WhatsApp and Instagram	Yes	The synced catalog enters the assistant's knowledge base
Messaging a Trendyol buyer	No	Trendyol has no buyer-to-seller messaging channel
Reaching the buyer's phone or e-mail	No	Contact details are masked; the e-mail is a Trendyol proxy address
Adding a phone number, link or e-mail to an answer	No	Trendyol policy bans advertising and contact details in answers
Editing or deleting a published answer	No	The API only has endpoints to list questions, read one question and post an answer

In short, a "Trendyol store assistant" works in two places: inside Trendyol, in the public Q&A area, and outside Trendyol, with the customers who already talk to you on WhatsApp or Instagram. The bridge between the two is the same catalog and the same order data.

Why are Trendyol customer questions so critical?

Because the rules are strict and the clock is short. According to Trendyol's published "Customer Questions Feature Rules" (Trendyol policy document):

• Questions are answered by the seller within 24 hours. Questions not answered within 24 hours trigger a reminder e-mail, and the seller gets 24 more hours after the reminder; the total window is 48 hours.
• Non-answers such as "we will get back to you shortly" do not stop the clock; the 48-hour counter keeps running.
• Sellers who answer late see their seller score affected negatively.
• Answers may not contain advertising or contact details. A seller who steers customers to their own store, website, phone or e-mail faces the penalties in the Seller Partnership and Listing Agreement, and accounts that receive complaints for this are temporarily suspended. Even contact details in an e-mail signature count as a violation.
• Trendyol continuously scans published questions and answers for banned words. The scan can reduce product visibility; a seller warned 3 times loses seller score and has the account temporarily suspended.
• Answers are also e-mailed to the customer; visibility can be set in the seller panel to "everyone sees" or "only the customer sees".

Trendyol's API documentation adds the technical limits (Answering Customer Questions): an answer must be between 10 and 2000 characters, only questions in "waiting for answer" status can be answered, an answer containing a banned word is rejected and the question returns to waiting status, repeated rejections close the question permanently, and a question not answered within 3 business days can never be answered again.

The two documents give two different windows: the policy says 48 hours, the API says 3 business days. The practical reading is this: aim for 24 hours to protect your seller score, and treat 3 business days as the absolute limit before the question closes for good.

The commercial value of speed is measurable too. Entagl's Response Velocity Study (2026), covering 32,581 conversations in 9 countries, found that conversations answered within 60 seconds converted at 35.1%, while those answered in 1 to 24 hours stayed at 7.1%. In the same study, 78.4% of buyers who wrote to several sellers at once bought from the seller who replied first. Trendyol's Q&A area is the public version of that race: your answer is visible not only to the person who asked, but to everyone who lands on that product page.

How does AI answer Trendyol questions?

In Entagl's Trendyol integration the process has six steps:

1. Connection. In the Trendyol seller panel, the Seller ID, API Key and API Secret are on the Integration Information page under My Account Info (according to Trendyol, only the panel's master user sees them: Authorization). The three values are entered in Entagl, the connection is verified instantly, and the keys are stored encrypted. No OAuth, no app approval.
2. Pulling the questions. Trendyol offers no webhook for questions; waiting questions are pulled in scheduled polling runs (the API query window is at most 2 weeks, 50 questions per page). Each question is saved in Entagl with the product name and its 3-business-day answer deadline.
3. Draft. The assistant writes the answer from the synced product data (current price, stock, attributes), your FAQs and your business information. Tone and language are your settings.
4. Guard layer. Before publishing, every draft passes deterministic checks: the 10 to 2000 character limit; removal of phone numbers, e-mails and links; removal of other marketplace or store names. The answer language is steered by your choice in the Settings tab. This layer stops the AI from breaking a rule "with good intentions".
5. Review or automatic publishing. The default mode is review: the draft waits in Entagl, you edit and approve, and it goes to Trendyol with one click. In automatic mode an answer that passes the guard layer is published directly on the next polling run.
6. Outcome tracking. If Trendyol rejects a published answer, the question is automatically moved to the review queue and is never re-sent on its own. At most two attempts are made per question, because a repeated rejection closes the question permanently.

The critical point of this design is that compliance with Trendyol's rules is not left to the AI. Everything that carries a violation risk (contact details, links, length) is blocked at the code level, independently of the model.

Review mode or automatic mode?

Criterion	Review mode (default)	Automatic mode
Who publishes the answer?	You, with one click	The assistant, once the guard layer passes
Speed	The moment you approve	Delayed only by the polling interval
Risk	Lowest; every answer passes a human eye	Low; guard layer plus automatic fallback to review
Who is it for?	New stores, technical products, high-risk categories	Stores with frequent, repetitive questions that have watched the drafts for a while

Our recommendation is simple: stay in review mode for at least the first week, see the quality of the drafts, then switch to automatic. If an answer is rejected, that question falls back to review mode on its own. This is the human-in-the-loop AI approach adapted to Trendyol: the AI writes, the human governs.

How do the Trendyol catalog and orders connect to a WhatsApp and Instagram assistant?

You cannot DM your Trendyol customer. But every day there are customers who saw you on Trendyol and wrote on Instagram, or asked about an order status on WhatsApp. The second half of the integration is for them.

Catalog. Your approved, on-sale Trendyol products are synced into Entagl: each barcode is kept as its own record with sale price, list price when there is a discount, stock quantity, category, brand, images, variant attributes such as size and color, and the Trendyol product link. The first import starts right after connecting, the catalog is refreshed by scheduled syncs, and you can trigger it with one click whenever you want. These products carry a Trendyol label in your catalog; products you added by hand or synced from Shopify are not touched. The assistant uses the same data on Instagram, WhatsApp, Facebook Messenger, Telegram and web chat; when a customer asks "do you have this in size 38", it checks current stock and shares the Trendyol product link.

Orders. Trendyol's webhook infrastructure delivers shipment-package status changes instantly (according to Trendyol's documentation, webhooks cover order statuses only, a seller can register at most 15 webhooks, and failed deliveries are retried every 5 minutes: Webhook Model). Entagl registers the webhook on your behalf automatically and runs periodic polling as a backstop. Trendyol statuses are translated into the language the assistant understands:

Trendyol package status	What the assistant says
Created, Picking, Invoiced, UnPacked, Awaiting, Verified	Being prepared
Shipped, AtCollectionPoint	Shipped
Delivered	Delivered
Cancelled, UnSupplied, Returned	Cancelled or returned
UnDelivered	Could not be delivered

When a customer types an order number on WhatsApp, the assistant finds the order and reports its status. Trendyol orders are labeled as their own channel in Entagl; they do not mix with Shopify or direct orders in reports.

There is no extra setup for this link. Whatever information your Instagram and WhatsApp assistant already uses, the Trendyol data flows into the same place. We covered the basic setup in our guide to automating Instagram and WhatsApp DMs; the Trendyol integration sits on top of that setup.

What Trendyol does not allow (honest limits)

Be careful with any claim that an AI tool will "do everything" for Trendyol. The platform's limits are these:

• No messaging buyers. Trendyol has no chat channel between seller and buyer. Reaching a Trendyol customer on WhatsApp or Instagram is not possible either; contact details are masked in the API.
• Answers are one-shot. The Trendyol API has no endpoint to edit or delete a published answer; what goes out stays on the product page as it is. This is why review mode is the default.
• The banned-word check also runs after publishing. An answer can be rejected; a repeated rejection closes the question permanently. This is why the assistant never re-sends a rejected answer automatically.
• Question notifications are not instant. Because Trendyol offers no webhook for questions, they are pulled in scheduled polling runs; a delay between runs is normal. Against a 3-business-day window that difference is irrelevant.
• Order answers are status-based. The assistant says which stage an order is at; it does not log into the carrier's system for a live location.
• Stores using Shopify and Trendyol at the same time currently have order lookups based on Shopify. This is a known, documented limit.
• AI does not create demand. It cannot write an answer for a product that receives no questions, and it does not bring traffic. It makes sure you do not lose the question and the customer that do arrive.

Setup: three fields, zero code

1. In the Trendyol seller panel, open My Account Info > Integration Information (with the master user account).
2. In Entagl, go to Channels > Trendyol and enter the Seller ID, API Key and API Secret. The connection is verified instantly.
3. The first catalog import starts on its own right after connecting; you can trigger it again any time from the Catalog tab. Your products are in the assistant's knowledge base shortly after.
4. In the Settings tab, choose the Q&A mode (default: review before posting) and the answer language (default: the language the customer wrote in).
5. Review the first drafts. Edit the answers whose tone you do not like; the assistant learns from your business information and your FAQs.

The Trendyol Q&A feature is not a separate product; it is part of the Receptionist. Every generated draft counts against your normal AI usage; there is no extra module fee and no per-channel fee.

FAQ

Can AI send messages to customers on Trendyol?

No. Trendyol has no messaging channel between buyer and seller, and buyers' contact details are masked in the API. An AI assistant can only answer the public customer questions on the product page. Outside Trendyol, it can talk to the customers who write to you on WhatsApp or Instagram.

Will my store be penalized if AI answers Trendyol questions?

Trendyol looks at the content of the answer, not at who wrote it: advertising, contact details, banned words and timing. A properly built assistant enforces those rules at the code level (removal of phones, links and e-mails, the character limit, deadline tracking). If you want to take no risk at all, review mode means you approve every answer yourself.

Which language does a Trendyol AI assistant answer in?

By default, the language the customer asked in; on Trendyol that is almost always Turkish. If you prefer, you can set a fixed answer language in Settings. On the WhatsApp and Instagram side the assistant detects the language the customer writes in and replies in the same language, across more than 100 languages.

How current are price and stock?

The catalog is synced automatically on a schedule and can be refreshed with one click whenever you want. A price or stock change you make on Trendyol reaches the assistant at the next sync. On campaign days a manual sync is recommended.

Can Trendyol orders be tracked on WhatsApp?

Yes. Trendyol order statuses reach Entagl instantly through the webhook, with periodic polling as a backstop. When a customer types the order number, the assistant reports whether the order is being prepared, shipped, delivered or cancelled.

Does this make sense for a store that sells only on Trendyol?

Yes, for two reasons. First, the Q&A load: every question has to be answered within 3 business days, within the rules and in public. Second, the customers who see you on Trendyol and write on Instagram or WhatsApp; answering them with current stock and price and the Trendyol product link converts directly into sales.

What happens if I disconnect Trendyol?

The synced Trendyol products are removed from your catalog; your orders and answered questions are kept in Entagl. Questions still waiting for an answer remain open in your Trendyol panel and can be answered there.

Conclusion: be the first answer to the question on Trendyol

On Trendyol the store that wins is the one that answers the question on the product page in time and within the rules. An AI assistant takes on that work at the draft level, you approve, and the risk of a rule violation is blocked in code. The same catalog and order data also answers your customer's question on WhatsApp and Instagram.
