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.

note

The GetTransactionStatus API is available only on https://api.zilliqa.com/. It is disabled for community-hosted or private-hosted seed nodes.

danger

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.
