/wallet/getapprovedlist

Return the list of addresses that have already signed a multi-sig transaction (does not compute weight, just lists signers).

• Source: framework/src/main/java/org/tron/core/services/http/GetTransactionApprovedListServlet.java
• Method: POST
• Response: api.TransactionApprovedList (api.proto)

Request parameters

Same body as /wallet/getsignweight:

Field	Type	Required	Description
raw_data	object	Yes	Same as createtransaction response
raw_data_hex	string	No (node ignores)	Same as broadcasttransaction: client display helper, not used for signature verification
signature	string[]	Yes	Collected signatures
visible	bool	No	Format of address / text fields (the response includes result.message, which is affected by visible)

Example: the request body is a Transaction JSON with signature, structured the same as /wallet/broadcasttransaction.

curl --request POST \
     --url https://nile.trongrid.io/wallet/getapprovedlist \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "raw_data":     { "...": "..." },
  "raw_data_hex": "0a02...",
  "signature":    ["b8c0...01"]
}
'

The above is a placeholder; the real request body is a multi-sig transaction JSON with at least one signature (from /wallet/createtransaction etc., then signed).

Response

Field	Type	Description
approved_list	repeated bytes	Signed addresses; base58 array when visible=true, hex (21 bytes, 41 prefix) when visible=false
result.code	enum	SUCCESS / SIGNATURE_FORMAT_ERROR / COMPUTE_ADDRESS_ERROR / OTHER_ERROR
result.message	string	Error description (UTF-8 when visible=true, otherwise hex)
transaction	TransactionExtention	Original transaction; its transaction.transaction is rewritten by Util.printTransactionToJSON into a complete unsigned-transaction JSON (with txID, raw_data.contract, raw_data_hex)

Response example:

{
  "approved_list": ["41dd791d6b49e190062d650e6a23c575510d35f2f9"],
  "result":       { "code": "SUCCESS" },
  "transaction": {
    "txid":        "<computed from raw_data>",
    "transaction": { "...": "..." }
  }
}

Note: signature parse and address recovery errors do not go through Util.processError — they are written into the response's result.code / result.message (HTTP 200). The table below only lists failures that produce {"Error": ...}-shaped responses.

Error responses

Trigger	Response
Request body exceeds node.maxMessageSize	{"Error": "class java.lang.Exception : body size is too big, the limit is <N>"}
Request body is not valid JSON	{"Error": "class com.alibaba.fastjson.JSONException : <parser info>"}
Missing raw_data, raw_data.contract is not an array, signature is not an array or its elements are not hex, field type mismatch in raw_data, etc.	{"Error": "class java.lang.NullPointerException : null"} (Util.packTransaction silently catches JsonFormat$ParseException / ClassCastException and returns null; downstream getTransactionApprovedList(null) triggers NPE)
Other exceptions	{"Error": "<exceptionClass> : <message>"}
