# Withdraw from Wallet - Self-Custody Multisig (Manual)

Source: https://developers.bitgo.com/docs/withdraw-wallet-type-self-custody-multisig-manual

## Overview

You build withdrawals from self-custody multisignature wallets by submitting transaction details to BitGo. BitGo uses the data you pass to construct an unsigned transaction that wallet co-signers can sign and wallet admins can approve. Once the transaction is half signed and approved, you send it to BitGo for final signing and broadcasting to the blockchain.

If you don't need this level of granular control for your withdrawals, see the integration guide for the [Express](/docs/withdraw-wallet-type-self-custody-multisig-simple) flow.

## 1. Build Transaction

Build the transaction by specifying the transaction details and sending them to BitGo. The following example is shows the minimum required parameters for sending bitcoin.

>Endpoint: [Build a Transaction](/reference/v2wallettxbuild)

```shell cURL
export COIN="<ASSET_ID>"
export WALLET_ID="<YOUR_WALLET_ID>"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export ADDRESS="<DESTINATION_ADDRESS>"
export AMOUNT="<AMOUNT_IN_BASE_UNITS>"

curl -X POST \
  https://app.bitgo-test.com/api/v2/$COIN/wallet/$WALLET_ID/tx/build \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -d '{
    "recipients": [
      {
        "amount": "'"$AMOUNT"'",
        "address": "'"$ADDRESS"'",
      }
    ]
  }'
```
```js JavaScript
let params = {
  recipients: [
    {
      amount: `<AMOUNT>`,
      address: `<DESTINATION_ADDRESS>`,
    },
  ],
};
wallet.prebuildTransaction(params).then(function (transaction) {
  // print transaction details
  console.log(JSON.stringify(transaction, null, 2));
});
```

> 📘 **Note**
>
> If you're building transactions for a UTXO asset in quick succession, BitGo recommends reserving unspents by passing the `reservation` and `expireTime` parameters. Reserving unspents avoids errors by ensuring the UTXO aren't included in subsequent builds.

#### Step Result

BitGo uses the data you pass to build an unsigned transaction. The following example builds a withdrawal of 10,000 sats of TBTC4.

## 2. Sign Transaction

Using the `txHex` and `txInfo` returned in the prior call, sign the transaction using your private key.

}
```

## 3. Send Transaction

Using the `txHex` returned in the prior step, send the half-signed transaction to BitGo.

#### Step Result

If your withdrawal doesn't require approval, BitGo applies the final signature using the BitGo key and broadcasts the transaction to the blockchain. If you [Create Policy Rules](/docs/wallets-whitelists-create) to require approvals on withdrawals, the transaction remains in a pending-approval status until a wallet admin approves it.

## 4. Approve Transaction (Optional)

> 📘 **Note**

> If you configure an approval requirement for withdrawals, you can't approve your own transactions - another admin must approve them.

>Endpoint: [Update Pending Approval](/reference/v2approvalupdate)

```shell cURL
export APPROVAL_ID="<APPROVAL_ID>"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export OTP="<YOUR_OTP>"

curl -X PUT \
  https://app.bitgo-test.com/api/v2/pendingApprovals/$APPROVAL_ID \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -d '{
    "state": "approved",
    "otp": "'"$OTP"'"
  }'
```
```js JavaScript
const baseCoin = this.bitgoSDK.coin(initialPendingApproval.coin);
const pendingApproval = await baseCoin.pendingApprovals().get({ id: initialPendingApproval.id });
const result = await pendingApproval.approve(params);
```

#### Step Result

Once approved, BitGo rebuilds the half-signed transaction, applying the most up-to-date fees. BitGo then applies the final signature using the BitGo key and broadcasts the transaction to the blockchain.
