Can I use a custom trading bot with a Bybit API key?

API Integration Capabilities

1. Bybit provides REST and WebSocket APIs that support order placement, position management, account balance retrieval, and market data streaming.

2. Developers can register API keys through the Bybit user interface under the API Management section.

3. Each API key must be assigned specific permissions—such as read-only, trading, or withdrawal access—based on operational requirements.

4. IP whitelisting is enforced for security; only requests originating from pre-approved IPv4 addresses are accepted.

5. Signature-based authentication using HMAC-SHA256 ensures request integrity and prevents tampering during transmission.

Bot Development Constraints

1. Custom bots must comply with Bybit’s rate limits: 120 requests per second for private endpoints and 60 for public ones.

2. Order execution latency depends on network conditions and bot architecture—not Bybit’s infrastructure directly—but excessive retries may trigger temporary throttling.

3. Margin trading bots require explicit handling of leverage adjustments, position mode switching (one-way vs. hedge), and risk limit tiers.

4. Futures and perpetual contracts demand precise timestamp synchronization to avoid signature expiration errors, especially when operating across time zones.

5. Webhook integrations are not natively supported; developers must poll order status or consume WebSocket streams for real-time updates.

Security Protocols for Key Handling

1. API keys should never be hardcoded into source files or committed to version control systems like GitHub.

2. Environment variables or secure vaults such as HashiCorp Vault or AWS Secrets Manager are recommended for credential storage.

3. Private keys used for signature generation must remain inaccessible to frontend code or client-side scripts.

4. Revocation of compromised keys is immediate and irreversible via the Bybit dashboard or API call to /user/post-api-key-revoke.

5. Two-factor authentication remains mandatory for account-level actions—even if the API key itself lacks withdrawal privileges.

Regulatory and Compliance Considerations

1. Bots executing high-frequency strategies may fall under jurisdictional definitions of algorithmic trading, requiring registration in certain regions.

2. Bybit prohibits API usage for front-running, spoofing, wash trading, or any activity violating their Terms of Service.

3. Users must retain full responsibility for losses incurred due to logic flaws, misconfigured parameters, or unhandled edge cases in custom code.

4. Cross-margin positions managed by external bots must align with Bybit’s margin call thresholds and auto-deleveraging rules.

5. Data residency policies apply—the API does not guarantee storage location of logs or metadata generated during bot interactions.

Frequently Asked Questions

Q1. Can I use the same API key for both spot and derivatives trading?Yes, provided the key has been granted permissions for both categories during creation. Permissions are set at key-generation time and cannot be modified afterward.

Q2. Does Bybit restrict API access based on account verification level?No, KYC status does not gate API functionality. However, unverified accounts face lower withdrawal limits and cannot access certain contract types.

Q3. What happens if my bot sends an invalid signature?The API returns HTTP 401 with error code 10004, indicating signature verification failure. Timestamp skew beyond 30 seconds also triggers this response.

Q4. Are testnet API keys compatible with mainnet endpoints?No. Testnet keys only function against https://api-testnet.bybit.com. Attempting to use them on production endpoints results in HTTP 403.
