Introduction

When it comes to managing your digital assets securely, BitGo provides a structured process for withdrawing funds from your Go Account. This guide walks you through every step, detailing how to build, send, and approve a transaction with BitGo’s robust security measures. Whether you’re transferring crypto to another wallet or withdrawing fiat to your bank, follow along to ensure a smooth experience.

Understanding the Withdrawal Process

BitGo follows a rigorous transaction approval process to ensure security. Here’s an overview of how it works:

  1. Building the transaction – Providing the necessary transaction details.
  2. Submitting the transaction – Sending transaction data for signing.
  3. Approving the transaction (if required) – Completing verification steps.
  4. Finalizing the transaction – BitGo signs and broadcasts it.

For simpler withdrawal flows, you can refer to the Go Account Simple Integration Guide.

Step 1: Building Your Transaction

Before you initiate a withdrawal, consider the following:

  • Crypto withdrawals transfer your assets on-chain.
  • Fiat withdrawals to a whitelisted bank require a wire transfer with a $16 fee (additional bank fees may apply).

API Endpoint for Building a Transaction:

POST /api/v2/<asset_id>/wallet/<wallet_id>/tx/build

Example cURL Request:

export COIN="tbtc"
export WALLET_ID="your_wallet_id"
export ACCESS_TOKEN="your_access_token"
export AMOUNT="10000"
export ADDRESS="destination_wallet_address"

curl -X POST 
  https://app.bitgo-test.com/api/v2/$COIN/wallet/$WALLET_ID/tx/build 
  -H 'Content-Type: application/json' 
  -H "Authorization: Bearer $ACCESS_TOKEN" 
  -d '{
    "comment": "BTC transaction",
    "recipients": [
      {
        "amount": "'"$AMOUNT"'",
        "address": "'"$ADDRESS"'"
      }
    ],
    "sequenceId": "unique_id"
  }'

After executing the request, you’ll receive a JSON response containing transaction details.

Step 2: Sending the Transaction

Once built, the transaction must be signed and submitted.

API Endpoint for Sending a Signed Transaction:

POST /api/v2/<asset_id>/wallet/<wallet_id>/tx/send

Example cURL Request:

curl -X POST 
  https://app.bitgo-test.com/api/v2/$COIN/wallet/$WALLET_ID/tx/send 
  -H 'Content-Type: application/json' 
  -H "Authorization: Bearer $ACCESS_TOKEN" 
  -d '{
    "comment": "Finalizing BTC transaction",
    "halfSigned": {
      "payload": {
        "coin": "tbtc",
        "recipients": [
          {
            "amount": "'"$AMOUNT"'",
            "address": "'"$ADDRESS"'"
          }
        ]
      },
      "signature": "your_signature_here"
    }
  }'

Depending on your security policies, this transaction may now require approval.

Step 3: Approving the Transaction (If Required)

Some withdrawals require manual approval, especially if they involve large amounts or were flagged for additional security checks.

API Endpoint for Approving a Transaction:

POST /api/v2/<coin>/pendingapprovals/<approval_id>

Example cURL Request:

export APPROVAL_ID="your_approval_id"

curl -X POST 
  https://app.bitgo-test.com/api/v2/$COIN/pendingapprovals/$APPROVAL_ID 
  -H 'Content-Type: application/json' 
  -H "Authorization: Bearer $ACCESS_TOKEN" 
  -d '{
    "state": "approved",
    "walletPassphrase": "your_wallet_passphrase",
    "xprv": "your_extended_private_key",
    "otp": "your_otp_code"
  }'

After approval, BitGo will rebuild the transaction with updated fees before signing and broadcasting it.

Finalizing the Transaction

Once all approvals are completed:

  1. Video Verification (If Required) – Some transactions require a short video call with a BitGo Trust operator for identity confirmation.
  2. BitGo Signs and Broadcasts – Finally, a BitGo Trust operator signs the transaction, and it is broadcasted to the network.

Track your transactions using the BitGo platform or a blockchain explorer.

That’s it! You’ve successfully processed a secure withdrawal from your Go Account using BitGo. By following these steps, you ensure that your transactions are both seamless and protected by industry-leading security protocols.
