API Permissions Review for Crypto Accounts

A connected exchange account should give a portfolio platform visibility, not control. That distinction is the purpose of an API permissions review: confirming that every API key connected to your crypto workflow can retrieve the data you need without gaining the ability to trade, transfer, withdraw, or change account settings.

For traders managing assets across several exchanges, API connections eliminate manual tracking and make tax reporting far more accurate. But convenience should never lead to broad permissions by default. A key that can do more than your reporting or portfolio tool requires creates an unnecessary operational risk.

What an API permissions review checks

An API key is a credential that lets one application communicate with another. On an exchange, that key can carry a specific set of permissions. The safest configuration depends on the job the connected application performs.

A portfolio dashboard generally needs to read balances, transaction history, open orders, fills, deposits, withdrawals, and sometimes derivatives positions. Tax software may need much of the same historical data. Neither use case requires permission to place an order or move funds.

Your review should answer a simple question for each connection: does this key have only the minimum access required to deliver its intended function? This is the principle of least privilege, applied to crypto account operations.

Read-only access is the standard for portfolio aggregation and tax reporting. It lets a platform calculate holdings, cost basis, realized gains, allocation changes, and performance history while your assets remain on the exchange accounts you control. A non-custodial platform should not need withdrawal authority to show you a unified portfolio view.

Permissions to allow, restrict, and question

Exchange labels vary. One may call a setting “read,” another may call it “view,” “data access,” or “account information.” Do not rely on the label alone. Read the exchange’s permission description and confirm what data the key can access.

For a tracking and reporting connection, these permissions are commonly appropriate:

• Read account balances and asset details
• Read deposits, withdrawals, transfers, orders, and trade history
• Read open orders, fills, fees, and derivatives positions when relevant
• Read wallet or subaccount data when you intend to track those accounts

The following permissions should generally remain disabled for a portfolio management, education, or tax workflow:

• Spot, margin, or derivatives trading
• Withdrawals, internal transfers, or address-book changes
• Account administration, API key management, or security-setting changes
• Payment, lending, staking, or borrowing actions unless a specific tool clearly requires them

Trading permission is not equivalent to withdrawal permission, but it still creates material exposure. If a compromised key can place market orders, it may be able to convert assets into less desirable holdings, generate taxable activity, or disrupt an active position. The correct setting is not “probably fine.” It is the narrowest setting that supports the connection’s documented use.

There are exceptions. A dedicated execution bot may legitimately require trading access. In that case, use a separate API key for that bot, limit it to the required account or subaccount, and never reuse that key for tax software or a portfolio dashboard. Separation limits the blast radius if one provider, device, or credential is compromised.

Read-only does not mean risk-free

Read-only keys cannot move funds, but they can expose sensitive financial information. Depending on the exchange, a key may reveal balances, trading behavior, transaction history, wallet addresses, or account identifiers. Treat it as confidential.

Use a unique key for each service rather than connecting one broadly permissioned key everywhere. Unique keys make audits easier and let you revoke access to one platform without interrupting every other integration. They also give you a clear record of why each connection exists.

A practical API permissions review workflow

Start with an inventory. List every exchange, subaccount, wallet service, bot, dashboard, tax platform, and developer tool connected to your accounts. Include services you stopped using. Old keys are easy to forget, especially after changing exchanges, upgrading tools, or testing a new product during a volatile market.

For each key, record the exchange, creation date, stated purpose, permissions, IP restrictions, last activity, and the person or system responsible for it. If the exchange shows no recent usage and you cannot identify the key’s purpose, revoke it. There is little value in keeping dormant access alive.

Next, compare actual permissions against required permissions. If a portfolio platform only needs transaction and balance data, remove trading and withdrawal permissions before entering the key into the platform. If an exchange does not let you modify an existing key, create a new read-only key, update the connection, verify that data syncs correctly, then delete the old key.

Then review scope. Some exchanges let you choose specific accounts, products, or subaccounts. Restrict the key to only the accounts you want included in your dashboard. This matters for users who separate long-term holdings from active trading capital, operate a small business account, or maintain different strategies across subaccounts.

Finally, check technical controls. IP allowlisting can add protection when a provider publishes stable connection IP addresses and your exchange supports restrictions. It is useful, but it can also cause sync failures if the provider changes infrastructure or uses distributed systems. Enable it when you understand the operational trade-off and have a process for updating it.

Avoid the most common setup mistakes

The most common mistake is enabling every available permission because it appears faster. It may save a minute during setup, but it creates a permission profile that is harder to defend and harder to audit later.

Another mistake is sharing keys. Do not send API secrets through email, chat, screenshots, or a spreadsheet. The secret is typically displayed only once for a reason. Store it only where it is needed to establish the encrypted connection, then remove local copies from notes, downloads, and clipboard managers where practical.

Users also confuse API keys with login credentials. Both deserve protection, but the controls differ. Your exchange login should have a unique password, strong multi-factor authentication, anti-phishing protections where available, and withdrawal address controls. Your API key should be purpose-specific, minimally permissioned, monitored, and revocable.

A final mistake is assuming that connected data is automatically complete. Read-only keys can still fail to retrieve a particular product type, historical period, subaccount, or transaction category. After connecting, reconcile the dashboard against the exchange. Check total balances, recent trades, deposits, withdrawals, and derivatives activity. A secure connection is only useful if the imported record is accurate.

When to repeat your review

Run an API permissions review when you connect a new service, change exchanges, add a trading bot, move assets into a subaccount, or notice an unfamiliar security alert. For active multi-exchange traders, a quarterly review is a sensible baseline. For lower-frequency investors with fewer connections, reviewing at tax time and after major account changes may be sufficient.

The right cadence depends on how quickly your setup changes. More exchanges, more automation, and more users with account access call for more frequent checks. If you manage an account with partners, employees, or family members, document who can create keys and who has authority to revoke them.

The Crypto Hub is designed around this boundary: users connect exchange APIs for portfolio visibility and reporting while retaining custody and execution control at their exchanges. That model works best when each API key is configured deliberately, not treated as a one-time setup task.

Your portfolio operation becomes easier to manage when every connection has a defined purpose, a limited scope, and an owner. Take ten minutes to inspect your keys before the next connection, not after an account alert forces the issue.
