Only 3 APIs to Achieve Binance-Grade Deposit Functionality
Provide a top-tier deposit experience for your applications using only three RESTful APIs from WARMKEY. Easy to integrate, secure by design, and fully controlled by the merchant.
Create Deposit Request – Initiate Secure Deposit Process
Call the Create Deposit Request API to generate a deposit link or UI, which you can embed via redirect or iframe. This endpoint supports customization through configuration and theme options, ensuring a seamless integration with your brand.
Query Log – Track Transactions in Real-Time
WARMKEY avoids webhooks—instead, use the Query Log API to programmatically poll for deposit or withdrawal updates. This allows you to monitor status changes, track incoming funds, and build real-time dashboards.
Create Withdrawal Request – Fully Controlled Outbound Process
Your business manages withdrawal operations via the Create Withdrawal Request API. Provisioning remains controlled by the merchant—withdrawal limits, timing, and authorizations are firmly in your hands.

Integration Ease: REST for Every Stack
All three APIs follow standard REST principles—HTTP POST or GET, JSON payloads, standard authentication. No matter what your tech stack is—PHP, Python, Ruby, Node, or Java—you can integrate in minutes. Learn about this endpoint
Unlike proprietary SDKs or custom libraries, REST works seamlessly everywhere.
Deposits Direct to You—No Middlemen
Deposits processed through WARMKEY go straight to your wallet (merchant-owned). No intermediaries, no custodial delays. You get the funds immediately—safer, more efficient, and completely frictionless.
Developers Stay Secure, in Control, and Fully Auditable
Fully Non-Custodial Security
Your deposits flow directly into your merchant wallet—no intermediaries, and crucially, your development team never handles private keys or seed phrases. This model drastically reduces risk exposure and aligns with non-custodial security best practices. Unlike custodial systems (where a single breach can compromise massive user funds), this method ensures control is entirely in your hands.
Smart Contract Safeguards with Controlled Withdrawal Provisioning
Withdrawals are governed by your own logic, reinforced by smart contract constraints. Only pre-approved amounts (via a rolling withdrawal allowance) can be executed—meaning even in the unlikely event of unauthorized access, the maximum amount at risk is strictly limited by your configured allowance. Moreover, implementing contract-level rate limits prevents rapid depletion and enhances system resilience.
Transparent, Real-Time Audit Trail via Query Log
The Query Log API provides full visibility and accountability for every deposit and withdrawal event. Through structured, time-stamped logs, you gain real-time transaction insights, streamlining reconciliation, auditing, and debugging—all without heavy overhead. This transparent trail not only gives developers peace of mind but also empowers compliance and incident investigation.
