# Wait for transaction by hash

`GET /transactions/wait_by_hash/{txn_hash}`

Same as /transactions/by_hash, but will wait for a pending transaction to be committed. To be used as a long
poll optimization by clients, to reduce latency caused by polling. The "long" poll is generally a second or
less but dictated by the server; the client must deal with the result as if the request was a normal
/transactions/by_hash request, e.g., by retrying if the transaction is pending.
