Perpetual Futures API Integration Guide: Account, Orders, and Positions | 6MM

For platforms that already have a user system, app, or digital wallet, integrating perpetual contract APIs can add contract trading functions to existing products and reduce the work of repeatedly developing the underlying trading system.

However, a complete integration is not just adding a trading page. It also requires connecting user accounts, market data, orders, positions, and asset flows, as well as completing exception handling and launch testing.

This article introduces the integration essentials of perpetual contract APIs/SDKs from four aspects: integration methods, account connection, trading processes, and launch acceptance.

1. What capabilities can perpetual contract APIs provide?

Perpetual contract APIs are interfaces between the platform and the trading system. Platforms obtain market data, submit trading instructions, and query accounts and positions through the interfaces, connecting trading capabilities into their own products.

Common integration modules include:

• Market Data: Obtain trading pairs, prices, and related market data.
• Order Management: Submit orders, cancel orders, and query order statuses.
• Position Management: Query positions and related trading statuses.
• Accounts & Assets: Connect user accounts, balances, and supported asset operations.
• Event Notifications: Synchronize business changes through real-time connections or callbacks.

The actual support scope, permissions, and fields shall be subject to the service provider's current documentation and project agreements.

2. How to choose between APIs, trading SDKs, and white-label systems?

Different platforms have different R&D conditions and product goals, and the suitable integration methods also vary.

Integration MethodSuitable RequirementsPlatform Main WorkAPI IntegrationCustomized trading pages and business process developmentFront-end development, interface integration, and maintaining trading statusTrading Component SDKEmbedding trading interfaces into existing web pagesConfiguring entry points, connecting logins and backend credentialsBackend SDKHandling user bindings, transfers, and business notificationsBackend integration, business record and callback processingWhite-Label ExchangeBuilding an independent brand trading platformConfirming functional scope, brand configuration, and operational processes

These methods can be used in combination. For example, the front end displays the interface through trading components, and the back end handles user binding and asset operations through the SDK.

6MM provides embedded API/SDK and white-label exchange solutions, allowing platforms to choose an integration path based on their existing products, R&D capabilities, and delivery requirements.

3. Account Connection: First Confirm "Who is Trading"

The platform's own user accounts need to establish a stable correspondence with the accounts in the trading system.

After a user logs into the platform, the platform backend should verify the identity before obtaining the trading account or trading entry credentials corresponding to that user. Do not allow account access or asset operations solely based on the user ID passed from the front end.

For example, when a wallet user clicks the "Contract Trading" entry, the system needs to confirm:

1. Who the currently logged-in user is.
2. Whether a trading account has been bound.
3. Whether the entry credential is valid.
4. Which accounts and features the user can access.

During the account connection stage, the handling methods for logouts, expired credentials, and duplicate bindings should also be clarified.

When using the 6MM Backend Agent SDK, the partner's API Secret should be stored in the backend, and the front end should only receive the required short-term results or entry credentials.

4. Connecting Market Data, Orders, and Positions

Market data, orders, and positions are three interrelated modules. The ability of the page to display prices does not mean that the trading process has been connected.

1. Market Data Subscription

The platform needs to connect to market data according to product requirements and handle connection interruptions, reconnections, and subscription restorations.

If market data stops updating, the page should prompt an exception to avoid continuing to display old prices as current market data.

2. Order Placement and Cancellation

After a user submits an order, the system needs to continuously track the order status.

A successful return of an API request should not be directly interpreted as "the order has been fully filled." The front end needs to display results such as order acceptance, fulfillment, or cancellation based on the actual status.

In case of a timeout, do not immediately assume that the order placement failed and resubmit. You should first query or check the original order status, and then process it according to the interface rules.

3. Position and Account Synchronization

After an order is filled, position and account statuses should be updated synchronously.

Real-time events can help pages display changes in a timely manner, while query and reconciliation mechanisms are used to restore status after connection interruptions. Combining both can reduce inconsistencies between the page and backend records.

During integration, precision processing for prices, quantities, and amounts, as well as order statuses, error codes, and time formats, should be standardized.

5. How to Handle Asset Transfers and Callbacks?

If the product involves asset transfers between platform accounts and trading accounts, the transfer direction, business number, query method, and reconciliation process must be clarified first.

Suppose a request times out after a user initiates a transfer. This does not necessarily mean the transfer failed. The transaction may have already completed, but the caller did not receive the result in time.

A safer handling method is to retain the original business number, check the actual status, and then decide whether to retry according to the rules supported by the interface to avoid duplicate transfers.

When receiving Webhook notifications, signature verification should also be completed, and processed events or business numbers should be recorded so that duplicate notifications do not repeatedly trigger deposits or other business operations.

The 6MM Backend SDK documentation provides integration instructions for user binding, asset operations, trading entry points, and callback verification. Platforms still need to complete their own business records, exception handling, and reconciliation mechanisms.

6. What to Check Before Launching Perpetual Contract APIs?

After successful interface debugging, it is also necessary to verify complete user processes and exception scenarios.

Before launching, monitoring, customer service, and technical support owners should also be confirmed, and request numbers, order numbers, and time records should be retained for easy issue location.

Logs should be desensitized to avoid exposing keys. At the same time, prepare trading entry suspension or rollback plans, and confirm user risk warnings, target market requirements, and the scope of responsibilities of both cooperating parties.

7. Frequently Asked Questions about Perpetual Contract API Integration

Do I still need to develop my own trading page after integrating the API?

If you adopt direct API integration, you usually need to develop the trading page and interaction flow yourself. If you adopt the trading component SDK, some interface development work can be reduced, but you still need to complete account, credential, and backend business integration.

If I already have an app or wallet, can I add contract trading?

You can evaluate the embedded API/SDK solution. It is necessary to focus on confirming the existing account system, trading entry points, asset processes, and mobile integration methods, rather than just looking at whether the page can be opened.

Is backend development still required after integration?

Usually yes. User identity verification, key management, asset business records, callback processing, and other tasks should be handled by the backend. Partner keys should not be directly placed into web or mobile code.

How long does it take to integrate perpetual contract APIs?

It depends on the integration method, account architecture, customization scope, and acceptance requirements. You should first determine the feature list and division of labor between both parties before estimating the implementation cycle.
