5.4.3.10 Get block information API

After the data is uploaded to the chain, the off-BSN system can use this interface on the PCN gateway to get the block information of the current transaction (body.blockInfo), the status (body.blockInfo.status), and transaction ID (body.blockInfo.txId). If the status value is 0, it signifies that the transaction has been successful and a block has been created. The block information can be queried according to the transaction ID.
