Send a half-signed transaction

post/api/v2/{coin}/wallet/{walletId}/tx/send

Send a half-signed transaction from the specified wallet. Instead of this endpoint, you likely want to use send transaction in the SDK.

Path Parameters

  • coinstringRequired
    A cryptocurrency or token ticker symbol.
    Example: "btc"
  • walletIdstringRequired
    Example: "59cd72485007a239fb00282ed480da1f"
    Pattern: ^[0-9a-f]{32}$

Request Body

comment string
Optional metadata (only persisted in BitGo) to be applied to the transaction. Use this to add transaction-specific information such as the transaction's purpose or another identifier that you want to reference later. The value is shown in the UI in the transfer listing page.
Max length: <= 256 characters
halfSigned object
The half-signed transaction. The request must include this or a txHex.
txHex string
txHex string
The half-signed, serialized transaction hex. Alternative to sending halfSigned.
txRequestId string
The transaction request id.
sequenceId string
A "sequenceId" is a unique and arbitrary wallet identifier applied to transfers and transactions at creation. It is optional but highly recommended. With a "sequenceId" you can easily reference transfers and transactions&mdash;for example, to safely retry sending. Because the system only confirms one send request per "sequenceId" (and fails all subsequent attempts), you can retry sending without the risk of double spending. The "sequenceId" is only visible to users on the wallet and is not shared publicly.
suppressBroadcast boolean
Do Not Use
videoApprovers array[string]
A list of public ids of users that should do the video id verification for the transaction that is being sent or initiated.
Min items: >= 1 items
numBlocks integer
(BTC only) Used to estimate the fee rate by targeting confirmation within the given number of blocks. If neither "feeRate" nor "numBlocks" is specified, a block target of 2 is used by default. Can be limited with "maxFeeRate".
Minimum: >= 2
Maximum: <= 1000
feeRateOne of
Custom minimum fee rate in a coin's base unit per kilobyte (or virtual kilobyte)--for example, satoshis per kvByte or microAlgos per kByte. For xrp, it refers to the open ledger fee in drops (1 XRP = 1000000 drops) and the actual fee used is usually 4.5 times the open ledger fee. If the applied "feeRate" does not meet a coin's required minimum transaction fee amount, the minimum is still applied (for example, 1000 sat/kvByte , a flat 1000 microAlgos or a flat 10 drops of xrp).
maxFeeRateOne of
Custom upper limit for fee rate in a coin's base unit per kilobyte (or virtual kilobyte)--for example, satoshis per kvByte or microAlgos per kByte. "maxFeeRate" can be used to limit a fee rate estimate generated with "numBlocks".
feeMultiplierOne of
Custom multiplier for fee rate. Suggested to be used in conjunction with "maxFeeRate" for higher priority transactions, or transactions which may not be broadcast for some time after being built. Must be greater than 0.
minConfirms integer
The unspent selection for the transaction will only consider unspents with at least this many confirmations to be used as inputs. Does not apply to change outputs unless used in combination with "enforceMinConfirmsForChange".
enforceMinConfirmsForChange boolean
When set to true, will enforce minConfirms for change outputs. Defaults to false.
Default: false
gasPriceOne of
Custom gas price to be used for sending the transaction. Only for ETH and ERC20 tokens.
eip1559 object
maxPriorityFeePerGasOne of
maxFeePerGasOne of
Max total gasPrice for EIP1559 transactions. Only for ETH and ERC20 tokens.
gasLimitOne of
Custom gas limit to be used for sending the transaction. Only for ETH and ERC20 tokens.
targetWalletUnspents integer
Specifies the minimum count of good-sized unspents to maintain in the wallet. Change splitting ceases when the wallet has "targetWalletUnspents" good-sized unspents. **Note**: Wallets that continuously send a high count of transactions will automatically split large change amounts into multiple good-sized change outputs while they have fewer than "targetWalletUnspents" good-sized unspents in their unspent pool. Breaking up large unspents helps to reduce the amount of unconfirmed funds in flight in future transactions, and helps to avoid long chains of unconfirmed transactions. This is especially useful for newly funded wallets or recently refilled send-only wallets. See [this support page](https://bitgo.freshdesk.com/support/solutions/articles/27000051851) for more info
Default: 1000
minValueOne of
Ignore unspents smaller than this amount of base units (e.g. satoshis). For doge, only string is allowed.
maxValueOne of
Ignore unspents larger than this amount of base units (e.g. satoshis). For doge, only string is allowed.
nonce string
(DOT only) A nonce ID is a number used to protect private communications by preventing replay attacks. This is an advanced option where users can manually input a new nonce value in order to correct or fill in a missing nonce ID value.
Example: 2000000
Match pattern: ^-?\d+$
noSplitChange boolean
Set "true" to disable automatic change splitting. Also see: "targetWalletUnspents"
Default: false
unspents array[string]
Used to explicitly specify the unspents to be used in the input set in the transaction. Each unspent should be in the form "prevTxId:nOutput".
changeAddress string
Specifies a custom destination address for the transaction's change output(s)
Max length: <= 250 characters
Example: 2MvrwRYBAuRtPTiZ5MyKg42Ke55W3fZJfZS
instant boolean
(DASH only) Specifies whether or not to use Dash's "InstantSend" feature when sending a transaction.
memo object
Memo for Stellar or EOS. Type is only required for memos in Stellar transactions. The memo contains optional extra information that can also be used to identify payments in Stellar or EOS.
type string
value string
addressType string
The type of address to create for change. One of "p2sh", "p2shP2wsh", and "p2wsh".
startTime string
The start of the validity window for the transaction. Only supported by HBAR
consolidateId string
(ALGO/TEZOS only) Consolidation ID of this consolidation transaction.
Example: 59cd72485007a239fb00282ed480da1f
Match pattern: ^[0-9a-f]{32}$
lastLedgerSequence integer
(XRP only) Absolute max ledger the transaction should be accepted in, whereafter it will be rejected
ledgerSequenceDelta integer
(XRP only) Relative ledger height (in relation to the current ledger) that the transaction should be accepted in, whereafter it will be rejected
cpfpTxIds array[string]
The list of transactions to bump with a child-pays-for-parent transaction (currently only bumping one tx is supported).
cpfpFeeRate integer
The desired effective fee rate of the accelerated transaction in base units per kilobyte (e.g. satoshi/kB), the unconfirmed transactions it depends on, and the newly created child-pays-for-parent transaction. Must be higher than the current effective fee rate of the target transaction.
maxFee integer
Limits the amount of satoshis that can be used for fees in a child-pays-for-parent (CPFP) transaction. CPFP transactions accelerate the targeted transaction and all of the unconfirmed transactions the targeted transaction depends on. "maxFee" is required for all CPFP transactions as it allows users to set a safety net that will halt CPFP attempts that exceed the expected cost.
Minimum: >= 0
strategy string
Optional unspent selection strategy to use. One of "RANDOM", "FIFO" or "BNB".
Max length: <= 20 characters
validFromBlock integer
Optional block this transaction is valid from
validToBlock integer
Optional block this transaction is valid until
