Issue with getting transfer details

Question

I'm trying to create something like solscan Token Transfers table for my token, like this:

I fetch transfers with logsSubscribe, but it returns like this:

{ "jsonrpc": "2.0", "method": "logsNotification", "params": { "result": { "context": { "slot": 285187688 }, "value": { "signature": "5vKUrLtJZ31sHt937DhBvKw6ciTzzBB7hNYFKxGzN7iBVimZ5QCzF7cRkPRkqQAvRghiHmxeNcX4AWnwiAbNhVsw", "err": null, "logs": [ "Program ComputeBudget111111111111111111111111111111 invoke 1", "Program ComputeBudget111111111111111111111111111111 success", "Program ComputeBudget111111111111111111111111111111 invoke 1", "Program ComputeBudget111111111111111111111111111111 success", "Program SW1TCH7qEPTdLsDHRgPuMQjbQxKdH2aBStViMFnt64f invoke 1", "Program log: Instruction: AggregatorSaveResult", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]", "Program log: Instruction: Transfer", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 4736 of 258278 compute units", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA success", "Program data: Dk7x7N2nVamjdokFdaa++3ClOmo2VJcejdN2ejwdTCWlI0gyCI0b7Wie/xAAAAAARd/yZQAAAAAKAAAAAAAAAA==", "Program data: A5o8/ZicmX6jdokFdaa++3ClOmo2VJcejdN2ejwdTCWlI0gyCI0b7UQzLUYAAAAAAAAAAAAAAAAJAAAAaJ7/EAAAAABF3/JlAAAAACdiSZSd8WPibtPO0qe9udGv2lY/3XQKaXRnpeHa0BnCAAAAAA==", "Program data: TOkj7nevZ9ajdokFdaa++3ClOmo2VJcejdN2ejwdTCWlI0gyCI0b7QAAAAAAAAAAJ2JJlJ3xY+Ju087Sp7250a/aVj/ddAppdGel4drQGcLBxFiwAAAAAMHEWLAAAAAA", "Program data: cB8z6WFkK/WjdokFdaa++3ClOmo2VJcejdN2ejwdTCWlI0gyCI0b7d2Hpm8bAAAAAAAAAAAAAAALAAAAaJ7/EAAAAABF3/JlAAAAAAAAAAAAAAAA", "Program data: TOkj7nevZ9ajdokFdaa++3ClOmo2VJcejdN2ejwdTCWlI0gyCI0b7dQwAAAAAAAAJ2JJlJ3xY+Ju087Sp7250a/aVj/ddAppdGel4drQGcLBxFiwAAAAADlpimIMAAAA", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]", "Program log: Instruction: Transfer", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 4736 of 164467 compute units", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA success", "Program SW1TCH7qEPTdLsDHRgPuMQjbQxKdH2aBStViMFnt64f consumed 143542 of 299700 compute units", "Program SW1TCH7qEPTdLsDHRgPuMQjbQxKdH2aBStViMFnt64f success" ] } }, "subscription": 1919 } }

How i can turn this data to like solscan's transfers table? Thank You.

Most of these tables use the preTokenBalances and postTokenBalances fields when fetching a transaction with getTransaction. You can see how they're defined at https://solana.com/docs/rpc/http/gettransaction
