GetTransactionStatus

---

Returns the status of a specified transaction. This API is available from Zilliqa V7.0.0 onwards and supports all transaction statuses (unconfirmed, confirmed, and rejected).

!!! note

The `GetTransactionStatus` API relies on an off-chain transaction tracking solution, which may be periodically cleaned. We recommend to still primarily use `GetTransaction` for older (e.g., several days old) transactions, and only use `GetTransactionStatus` mainly for tracking the progress of ongoing transactions.

2	17	Rejected - Contract & source account cross-shard issue
2	18	Rejected - Code size exceeded limit
2	19	Rejected - Transaction verification failed
2	20	Rejected - Gas limit too low
2	21	Rejected - Insufficient balance
2	22	Rejected - Insufficient gas to invoke Scilla checker
2	23	Rejected - Duplicate transaction exists
2	24	Rejected - Transaction with same nonce but same/higher gas price exists

2	255	Rejected - Internal error

!!! warning

The transaction pool is cleared by design **at the start of a new DS epoch**. Any transaction left in "Pending" state (e.g., "Pending - Dispatched", "Pending - Nonce is higher than expected", ...) after a new DS epoch has started will have most likely been dropped and will no longer be processed further at that point.
