there is another problem with sending the transaction. i use TONCENTER and sendBocReturnHash api to send the transaction.
so i get hash of the transaction. but this hash is for input of the transaction. not for the transaction. for example:

i got hash="1jB29o5zqO2Rz7F5yBvAk8fm1qWUJHaNurI33z52TV0=" from sendBocReturnHash.

but when i open the transaction in the explorer:
https://testnet.tonscan.org/tx/by-msg-hash/1jB29o5zqO2Rz7F5yBvAk8fm1qWUJHaNurI33z52TV0=

transaction is "vuyKeoni0Bz19JzNs9znYgREBn51ByGDjy6d7++sh74=".
what's wrong? how get this hash?

Tx hash is hash of transaction cell

Tonconnect hash is hash of transaction inMessage

So? Is the result correct? Should i do anything?

Could you explain more plz? What hash should I save as the transaction hash?

sendBocReturnHash returns hash of the message you sent. With that hash you can find the triggered transaction (and it's hash) at tonscan or using index API: https://toncenter.com/api/index/#/default/get_transaction_by_in_message_hash_v1_getTransactionsByInMessageHash_get
