Introduction

CS2DT is a B2B platform developed by HaloSkins, providing skin trading solution for companies and websites. The following instruction is only for businesses integrating with our B2B, not for individual traders.

HaloSkins OpenPlatform, on the other hand, is an API integration platform for regular traders. You can apply for open platform access here. The open platform can also automate your trading.

CS2DT offers over 1.5 million CS2 skins available on multiple platforms, including one of our largest partners, C5GAME. Approximately 40% of the skins (over 500,000) are delivered instantly within 3 minutes at highly competitive prices, often lower than what you see on the HaloSkins P2P marketplace. Furthermore, many manually delivered skins (over 1 million) are priced below BUFF. You can access all skins through our API for full automation, and we provide 24/7 technical support and direct support from a dedicated business manager. For a better user experience, we offer both cryptocurrency and fiat currency payment options.

CS2DT also supports Dota 2, making it ideal for businesses with multiple growth directions.

Currently, you can also sell your inventory to us through our platform. This includes items that are still on trading cooldown, which can be listed early!

Before you start

We prepared a detailed documentation about our API for your technical team. If you can't find the answer to your technical question after reading it, please check the current page, especially FAQ section. If you still can't find the answer, please contact your business manager or tech support. If you didn't get one yet - keep in touch with us at [email protected] or [email protected].

You can find API documentation here: CS2DT Open Platform Access Guide - cs2dt-open-en-v2

1 Open your account(s)

Next step is to register your first account at https://cs.haloskins.com. If you haven't get in touch with us yet - now it's the time. You can find our emails in previous step. Once you have a manager - please provide us with a phone number for registration. This number will be used for your initial login, you will receive a SMS code. If you can't get the code, please contact us. We can help you to receive it.

After logging in you can set MFA verification and password in profile settings. This allows you to login using password, without receiving SMS every time.

You can open more than one account, for example if you want separate crypto from fiat or real trading from testing account. Each account need a new phone number to register.

You might have seen some of our users using https://admin.cs2dt.com/login instead of https://cs.haloskins.com. Both address represent our platform and your account will work for both. The only two difference are the language and payment methods. First option is in Chinese with local Chinese payment via AliPay, and the second one is in English, accept crypto and international bank transfers.

2 Get API and Top-up your account

You can find your API key and set IP whitelist in API setting.

When top up, you will get a wallet address, the wallet address is bind to your account, so you can just transfer money to this address, the system will automatically help you credit the money. Rarely our provider may stop your transfer, if address is new. Please contact your manager in this case, we will whitelist your address to prevent such cases in the future.

• Please notice that the USDT and USD exchange rate might be not precisely 1:1. So the deposit exchange rate may change according to the recent crypto currency market.
• We accept USDT TRC-20 and ERC-20, but we need to provide you a permission separately, if you want to use ERC-20.
• For fiat transfers, please contact your manager to receive bank details. After the payment provide us with transaction confirmation. Once we receive money, we will credit them to your account.

3 Get the highest margin skins

We have a huge stock of skins priced lower than BUFF, which can provide you with great margin. The only downside is - these are skins with manual delivery, which may cause longer shipping time. The longest shipping time is 12 hours. To help you eliminate this downside and keep providing your users with the fastest shipping within your standards. We added several parameters, which can help you to sort skins by delivery time and delivery rate.

/product/v2/list/ids - here you can get average delivery time for seller.

Important fields:

To achieve the best delivery rate and time, we can recommend you limit purchasing manual delivery skins from midnight to 8:00 am UTC+8 , since a lot of sellers are in China and it's night time for them. You still can use lastActive (enum) to check if user is online during night time.

If for a moment you prefer to avoid manual delivery, please use the endpoint called “onlyWithAutoDeliverPrice”. When this field is true, only the data with the automatic shipment quantity greater than 0 will be filtered.

Place buy orders

To get more items with desired price you can place buy orders. It works great if you buying stock for your own bots. Set up the target price and if our end users are satisfyed with it, the order will be fulfilled. Read more about buy orders setting here.

4 Some system details and fees

• After opening of your account QPS/RPS is limited to 50. If you have some specific needs you can let our technical support know.
• The update time for full on-sale item list is every 20 minutes.
• Overdue orders canceled automatically by our system. Including orders not shipped within 12 hours, unconfirmed Steam offers after 30 minutes, not accepted offers within 24 hours
• You can cancel manually shipped order after 30 minutes. (If it is not shipped)
• Penalties may be applied for unfair order cancellation (read more below)

We provide sellers at least 30 minutes to fulfill manually shipping skin's orders. Our biggest supplier has order cancellation fee in some cases to compensate sellers potential loss. So a penalty for some orders canceled by buyer may occur.

Order cancellation penalty fee may apply:

• When the seller shipping time was within 30 minutes, a fee is required to cancel the order.
• When the seller sends the offer successfully, but buyer need to cancel the order after that, need to pay a certain fee.
• When the seller sends the offer successfully, because the buyer has not accepted the offer for more than 24 hours, or manually cancel the offer, or there is a counter-offer and other irregularities that lead to the cancellation of the order, need to pay a fee.

Penalty fee is 2% of the price of the skin with upper limit set to $9, and minimum is $0.01 (If the penalty fee is less than $0.01, it will be charged as $0.01). Please note on our side we always have this fee. Even if we reach an agreement to not apply penalties on you, based on our daily trading volume, we still must pay these fees by our own. To ensure the most beneficial cooperation for both sides, please pay attention on cancellation rate.

To prevent abusing cancellation fees mechanism, when a user refuses offer or initiates a counteroffer on Steam, or has not received a successfully sent offer for more than 24 hours, we will ban this user for 3 hours each time.

Regarding CS2DT's Penalty for Reversed Order:

• If the seller reverse the order: The seller account will be banned for days, and in serious cases, trading privileges will be permanently revoked. "The order amount will be always fully refunded to the CS2DT account via the original payment method."
• If the buyer reverses the order, no refund will be issued to the buyer, and 50% of the funds will still be settled to the seller. Buyers are advised to take note to avoid losses.
• In the future, penalties will be added for sellers who reverse orders. For details on API updates, please refer to the API documentation.

5 The common errors

For all the common errors, we have an API errors list here: Response codes - cs2dt-open-en-v2

For more comlpex questions, please read this page full and check FAQ below. There is a great chance we already prepared answer for you! If you still have a question, please contact your business manager or tech support.

6 Selling through API

Currently, our API supports listing and selling items. This includes regular items, as well as items currently in trading cooldown.

However, you will need to pay a certain amount of margin after listing items for sale.

You can use the same account for buying and selling, and transfer the sales balance to your purchasing balance to purchase skins.

6.1 Selling Regular Items

You can find documentation related to selling here: https://opendoc.cs2dt.com/en/doc-7727550

If you have any questions, please contact customer service.

6.2 Selling API Usage Flow:

When listing products, you need to use the Sell Create interface to list all products for sale.

When product prices are updated, you need to use the Sell Update interface to update the product price to the new price.

If your products are already listed on other platforms, but for some reason they are sold elsewhere, you need to use the Sell Cancel interface to remove the product's listing information.

If a product is not delisted, but is simultaneously purchased on cs2dt, a fail will be returned, and the product will be automatically delisted.

After your product is purchased on the platform, although it will be automatically delisted, to maintain consistency, we suggest you to send a notification every time the order status changes.

6.3 Selling Items in Trading Cooldown

You can also sell items in trading cooldown through our API. This means that while your item inventory is still within the seven-day trading cooldown period, you can use our API to list them early.

The balance from your sales can be used to directly purchase items through our API or withdrawn via USDT.

The process is roughly as follows: List the items currently in the cooldown period; once someone purchases them, these items will be removed from the list.

After the cooldown period ends, you will receive a notification that the item has been fulfilled.

If you cancel the shipment, you will be penalized 5% of the order amount.

7 After finished setup

We hope for a long-term cooperation with our partners, so we ask to sign a contract after all settings are ready and regular trading process started. Please coordinate with your business manager to achieve the condition with suits both of us the most.
