I use an API call to get the details of incoming and outgoing transactions from my address. I get block_height for some addresses while for some addresses I do not have a block height. Can I know why this problem is coming and what will be the reason? Based on block_height, the number of confirmations is reached, but without block height, I can not mark the transaction as confirmed.
Above, link results with block_height. Please give me the solution for this problem. Thank you in advance.
