The sendBocReturnHash method sends a serialized bag-of-cells (BoC) to the TON blockchain and returns the message hash. This method is similar to sendBoc but additionally returns the hash of the sent message for tracking purposes.

Response

  • ok (boolean) — Whether the operation was successful.
  • result (object) — The result of the operation. Contains:
    • @type (string) — The type of the result, typically raw.extMessageInfo.
    • hash (string) — The hash of the sent message. This can be used to track the transaction status.
    • @extra (string) — Extra information about the operation.

​
Use case

The sendBocReturnHash method is preferred over sendBoc when you need to track transaction status:
  1. Wallet applications can display the transaction hash to users for tracking.
  2. Backend services can store the hash for transaction monitoring and confirmation.
  3. Trading bots can track order execution status using the returned hash.
  4. Payment systems can correlate transaction hashes with internal records.
  5. DApps can provide users with explorer links using the transaction hash.
Here’s an example of sending a transaction and receiving the hash: 
curl -X 'POST' \
  'https://ton-mainnet.core.chainstack.com/f2a2411bce1e54a2658f2710cd7969c3/api/v2/sendBocReturnHash' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{

}'
Use the returned hash with getTransactions or a block explorer to confirm your transaction was processed successfully.
