API Transaction Builder — Generate Tron Transaction JSON

If your app is already able to build tron transactions, you don't need to utilize the transaction builder. This feture is for projects that are completely new to tron transactions to simplify the transaction payload generation.

#🧾 Input Required

A Sender Adress
A Receiver Address
The amount you want to send
For TRC20 and TRC721 transactions: The Smart Contract Address
Fopr TRC10 and TRC721 transactions: The TokenId

#How It Works

The Transaction Builder provides a simple API endpoint to generate raw Tron transactions. This is particularly useful for developers who are new to Tron or want to streamline the transaction creation process without dealing with the complexities of raw transaction payloads.

You can use the /transactions/build endpoint to create various types of transactions, including TRX, TRC10, TRC20, and TRC721 transfers.

 9  "receiver_address": "TSSMh4g9D2C1Jg9J3g9J3g9J3g9J3g9J3g9J3g9J3",

#Example Response

The API will return a raw Tron transaction JSON object, which you can then sign and broadcast.

 1{

 4      {
 5        "parameter": {
 6          "value": {

 8            "owner_address": "415b3648679f225021200000000000000000000000",
 9            "to_address": "415b3648679f225021200000000000000000000000"
10          },
11          "type_url": "type.googleapis.com/protocol.TransferContract"
12        },
13        "type": "TransferContract"
14      }
15    ],
16    "ref_block_bytes": "0000",
17    "ref_block_hash": "0000000000000000",
18    "expiration": 1678886400000,
19    "timestamp": 1678886340000
20  },
21  "raw_data_hex": "0a020000..."
22}

Once you have the raw transaction, you can proceed to sign it with your private key and then send it to the Tron network.
