Coinbase Advanced Trade 下单、认证与对账清单
已验证事实边界
1. Coinbase publishes API authentication documentation for Coinbase Developer Platform consumers. 2. Coinbase publishes Advanced Trade API order-management guidance for order workflows. 3. Coinbase publishes a Create Order endpoint in the Advanced Trade REST API reference. 4. Coinbase publishes Advanced Trade WebSocket endpoint documentation for streaming workflows. 5. Coinbase also publishes Exchange REST authentication documentation, showing that authentication shape depends on API surface. 6. A Coinbase API integration must separate authentication, order submission, stream events and reconciliation before live automation.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| API surface | Coinbase documents different API surfaces and authentication paths | name the exact API surface before coding | future route consolidation |
| Key scope | authentication proves key possession but not safe permission design | grant the least privilege needed and keep secrets outside evidence | private portfolio permissions |
| Order request | the Create Order endpoint is a request interface, not a risk engine guarantee | record request IDs and intended order semantics | account-specific rejection reasons |
| WebSocket stream | streaming endpoints can observe events but are not a complete audit log by themselves | pair streams with REST backfill | gap windows during reconnect |
| Reconciliation | order acknowledgement, fill state and cancel state can diverge during failures | build idempotent reconciliation before retries | partial-fill race conditions |
| Rate and retry | API clients can fail through timing, limits or network loss | use bounded retries and stop on uncertain state | current private rate bucket |
| Stop rule | stop when authentication, order state or stream evidence disagrees | freeze new automation until REST and logs reconcile | venue-side incident scope |

控制说明
1. API surface
这一项要求读者先把公开来源翻译成操作规则。这里的含义是：Coinbase documents different API surfaces and authentication paths。可执行动作是：name the exact API surface before coding。仍然未知的是：future route consolidation。因此本文不会把未知部分包装成安全承诺、收益承诺、官方背书、审批保证、注册诱导、可用性保证或产品推荐。
2. Key scope
这里的含义是：authentication proves key possession but not safe permission design。可执行动作是：grant the least privilege needed and keep secrets outside evidence。仍然未知的是：private portfolio permissions。
3. Order request
这里的含义是：the Create Order endpoint is a request interface, not a risk engine guarantee。可执行动作是：record request IDs and intended order semantics。仍然未知的是：account-specific rejection reasons。
4. WebSocket stream
这里的含义是：streaming endpoints can observe events but are not a complete audit log by themselves。可执行动作是：pair streams with REST backfill。仍然未知的是：gap windows during reconnect。
5. Reconciliation
这里的含义是：order acknowledgement, fill state and cancel state can diverge during failures。可执行动作是：build idempotent reconciliation before retries。仍然未知的是：partial-fill race conditions。
6. Rate and retry
这里的含义是：API clients can fail through timing, limits or network loss。可执行动作是：use bounded retries and stop on uncertain state。仍然未知的是：current private rate bucket。
7. Stop rule
这里的含义是：stop when authentication, order state or stream evidence disagrees。可执行动作是：freeze new automation until REST and logs reconcile。仍然未知的是：venue-side incident scope。
仍需明确的未知项
- future route consolidation
- private portfolio permissions
- account-specific rejection reasons
- gap windows during reconnect
- partial-fill race conditions
- current private rate bucket
- venue-side incident scope
实用结论
本文最有价值的地方是克制。Coinbase Advanced Trade API 上手应被视为经过认证的订单控制流程，而不是普通交易捷径。当前 Coinbase Developer Platform 文档把 API authentication、Advanced Trade order management、create-order endpoints 与 WebSocket endpoints 分成不同表面。实用结论是：任何自动化把 Coinbase 响应当成持久交易事实前，都应先映射 key scope、JWT 生成、REST 下单、WebSocket 事件消费、订单状态对账、rate-limit 处理和非秘密日志。 用户应获得一个更清楚的核验路径和停止条件，而不是一个看似肯定、实则无法由公开证据承担的承诺。
