Alternatively, direct HTTP requests can be made using tools like curl or standard HTTP client modules, requiring manual implementation of the signing process. Coinbase provides a Sandbox environment for development and testing, crucial before interacting with live markets. Verification of API integration logic and error handling. The Sandbox mirrors production API functionality but uses test funds and simulated market data. Familiarization with API request/response structures. Risk-free testing of trading algorithms.

Real-time executed trades for subscribed products. Mastering its authentication, understanding its data structures, respecting rate limits, and implementing robust operational practices are key to leveraging its full potential. This ensures that retrying a “place order” request is safe. This should be a unique identifier (e.g., UUID v4) generated by your client. Both orders are canceled. Indicates an issue with the subscription or connection. The Coinbase Exchange API provides a comprehensive toolkit for developers to build sophisticated trading applications and integrations. Continuous attention to Coinbase’s official developer documentation is crucial for staying updated on new features, endpoint changes, and best practices. Managing WebSocket connections involves handling reconnect logic, message sequencing (if applicable, via sequence numbers in messages), and local state maintenance (e.g., reconstructing an order book from snapshot and l2update messages). The older order is canceled. The stp parameter in order placement (POST /orders) helps prevent an account’s orders from matching with each other.

API Secret: A private, alphanumeric string (e.g., Asia S9vP3rK2sLqR7xW1yZ0aB5cD6fE8gH9i). CB-ACCESS-SIGN: The base64-encoded HMAC-SHA256 signature. CB-ACCESS-KEY: Your API Key. Always adhere to the principle of least privilege. This secret is displayed only once upon generation and must be stored securely. 2024!) created by you during key generation. API key permissions are granular, allowing you to restrict actions (e.g., view-only, trade execution, withdrawal capabilities). Coinbase Exchange API employs a signature-based authentication mechanism (HMAC-SHA256) for all private, authenticated endpoints.

API Versioning: Be mindful of API version changes (e.g., /v2/products, /v3/products).

Regular Audits: Periodically review API key usage and permissions. Monitor developer announcements for deprecation schedules and migration paths. Provide current product statuses. Subscription: After connecting, send a JSON message to subscribe to channels and product IDs. 2update: Incremental changes to the Level 2 order book (bids/asks added, changed, or removed). Coinbase Exchange provides WebSocket feeds for low-latency, real-time data. Real-time price, volume, and bid/ask updates. Periodic message to confirm connection health. API Versioning: Be mindful of API version changes (e.g., /v2/products, /v3/products). Initial state of the subscribed data (e.g., full order book snapshot for level2).

Exchanges charge interest for the money you borrow. This is known as the maintenance margin. Market conditions. You pay interest until the position is closed. If your losses reduce your equity below this threshold, the platform warns you to add more funds. If you don’t respond to a margin call by adding more funds, your position is closed through a forced liquidation. These rates vary by platform. This prevents further losses for the lender, but you lose your collateral. You must keep enough equity in your position to avoid a margin call.
