How to manage API permissions for spot trading on OKX?

API Permission Configuration for Spot Trading

1. Access the API Management section within your OKX account dashboard after completing identity verification.

2. Click “Create API Key” and select the specific permissions required for spot trading operations.

3. Enable the “Read” permission to retrieve balance information, order history, and market data.

4. Activate the “Trade” permission to place, cancel, and modify spot orders across all supported trading pairs.

5. Avoid enabling “Withdrawal” unless explicitly needed, as it introduces elevated security risk unrelated to spot execution.

IP Whitelisting and Authentication Hardening

1. Assign a static IPv4 or IPv6 address—or a CIDR subnet—to each API key used for spot trading.

2. Confirm that the IP binding is active before initiating any trade-related requests; unbound keys with trade permission expire after 14 days of inactivity.

3. Use HMAC-SHA256 signatures for every private endpoint call, incorporating timestamp, HTTP method, request path, and body hash.

4. Store the Passphrase separately from the Secret Key and ensure it is never logged or exposed in stack traces.

5. Rotate API keys quarterly and revoke obsolete ones immediately via the API management interface.

Spot Order Execution Constraints

1. Specify tdMode = 'cash' in all spot order payloads to prevent accidental margin or funding mode activation.

2. Validate price and size precision against OKX’s instrument metadata before submitting orders—BTC-USDT requires price precision of 0.01 and size precision of 0.00000001.

3. Set ordType = 'limit' or 'market' explicitly; omitting this field triggers default behavior inconsistent across environments.

4. Include clOrdId for client-side order tracking and avoid reusing identifiers across sessions.

5. Monitor response codes such as 50113 (signature mismatch) and 58007 (price deviation beyond auction range), both common in misconfigured spot submissions.

Testing Workflow Using OKX Demo Environment

1. Register a separate API key under the testnet domain with flag=1 to isolate simulation traffic from live balances.

2. Fund demo accounts using the OKX faucet without KYC requirements—each allocation expires after 72 hours.

3. Execute identical spot order logic on both testnet and production, comparing latency, rejection rates, and fill confirmation timing.

4. Verify that GET /api/v5/trade/orders-history-archive returns consistent pagination structure between environments.

5. Confirm that WebSocket subscription to books50-l2-tbt channels delivers real-time depth updates without authentication errors.

MiCA-Compliant API Governance for EU Users

1. OKX European Ltd holds full MiCA authorization covering all 30 EEA jurisdictions as of January 27, 2025.

2. EU-based API keys automatically enforce stricter rate limits: 15 requests per second instead of the global default of 20.

3. Trade endpoints return additional regulatory headers including X-MiCA-Jurisdiction and X-Compliance-Level.

4. All spot order confirmations include an immutable complianceReferenceId tied to the underlying asset’s MiCA registration status.

5. Withdrawal-related endpoints remain disabled for EU keys unless explicitly enabled through the MiCA compliance portal.

Frequently Asked Questions

Q: Can I use the same API key for both spot and futures trading?Yes, but only if “Trade” permission is enabled for both instType categories during creation. Separate keys are recommended for audit clarity.

Q: Why does my spot order return error code 58000?This indicates the requested instrument is suspended for trading. Check OKX’s official instrument status page or call GET /api/v5/public/instruments with instType=SPOT.

Q: Is Passphrase case-sensitive?Yes. OKX stores its SHA-256 hash, and any variation in casing produces an invalid signature.

Q: How do I verify whether my API key has been compromised?Review the “Recent Activity” tab in API Management. Unrecognized IPs, unexpected withdrawal attempts, or spikes in order cancellation volume signal exposure.
