+## Querying Transaction Results
+
+When querying transaction results (e.g., via HTTP/REST endpoints like `GET /v1/transaction_results/{id}`), you can provide either:
+- A **transaction ID** (256-bit hash as hex string)
+- A **scheduled transaction ID** (UInt64 as decimal string)
+
+The returned result always includes `transaction_id` as the underlying native transaction ID. For scheduled transactions, this will be the system transaction ID that executed the scheduled callback.
+
+Learn more about [Scheduled Transactions](/docs/build/cadence/advanced-concepts/scheduled-transactions.md).

 ## Transaction Finality
 
 As of **FCL v1.15.0**, it is now recommended to use use `onceExecuted` in most cases, leading to a 2.5x reduction in latency when waiting for a transaction result. For example, the following code snippet should be updated from:

 Flow provides a comprehensive suite of client tools and SDKs designed to help developers build applications that interact with the Flow blockchain. These tools support various programming languages and platforms, offering different levels of abstraction and functionality.
 
+> Terminology note

+> Anywhere an API or SDK accepts a Flow transaction ID, you may also provide a scheduled transaction ID:
+> - Transaction ID: 256-bit hash represented as a 64-character hex string
+> - Scheduled transaction ID: UInt64 represented as a decimal string
+> 
+> For REST endpoints like `/v1/transactions/{id}` and `/v1/transaction_results/{id}`, the server treats the `id` as a transaction ID if it parses as hex; otherwise, as a scheduled transaction ID if it parses as a decimal UInt64. Both return identical response schemas. See the Protocol docs for details (`docs/protocol/access-onchain-data/index.md`).
