Send Message

The message endpoint sends an external message to the TON network. This is the v3 API method for submitting signed transactions to the blockchain.
Get your own node endpoint todayStart for free and get your app to production levels immediately. No credit card required.You can sign up with your GitHub, X, Google, or Microsoft account.
TON pricing is the same for full, archive, v2, v3There’s no difference between a full node an archive node in data availability or pricing. All data is always available and all node requests are consumed as 1 request unit.

​
Parameters

  • boc (string, required) — The serialized bag-of-cells in base64 format containing the signed external message.

​
Response

  • message_hash (string) — The hash of the sent message, which can be used to track the transaction.

​
Use case

The message endpoint is essential for any application that needs to send transactions via the v3 API:
  1. Wallet applications broadcasting user-signed transactions.
  2. Smart contract deployment and interaction.
  3. DApps submitting user transactions to the network.
  4. Automated systems executing on-chain operations.
  5. Token transfer services sending Jetton or NFT transfers.
Here’s an example of sending a transaction: 
curl -X POST \
  'https://ton-mainnet.core.chainstack.com/f2a2411bce1e54a2658f2710cd7969c3/api/v3/message' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{

}'
Use the returned message_hash with the transactions or traces endpoints to track transaction status and execution results.
