A Permission Scope Checklist Before You Create an API Key

An API key is a credential that lets software act on your OKX account without your password and without your usual login prompts. That is exactly why beginners get into trouble: the key keeps working quietly in the background, long after the moment you created it. The most common mistake is broad scope. Many people tick every permission box because a tutorial told them to, or because a bot refused to start, and they end up with a key that can move funds when all they wanted was to read a balance. This guide walks you through a permission scope checklist you can run before you press the create button, and again whenever you review existing keys. It stays at the level of decisions and records, not settings you should copy blindly, because labels and options change and you should confirm the current wording on the official help centre and inside your account settings. Treat every scope as a separate decision: what does this permission allow, does the tool in front of me actually need it, and what would happen if the key leaked? If you cannot answer all three, remove the permission and test again.

Start by writing down what the software actually needs

Before you open the API management page, describe the job in one sentence. Examples: read my balances into a spreadsheet, place and cancel spot orders from a script, or monitor positions without trading. That sentence decides almost everything, because each permission scope maps to a category of action, and a tool that only reads data has no reason to hold a scope that can move funds.

Next, check the tool's own documentation for the minimum scope it requires, then compare that with what the OKX help centre says each scope permits. If the two disagree, or if the tool's guide is vague, do not guess upward. Create the key with the narrower scope and see whether the tool still works. A failed request is a cheap, reversible error; an over-permissioned key is not.

Write the result in a small note you keep: date, key label, the sentence describing the job, the scopes you chose, and the reason for each. When you review keys months later, that note is the only thing that tells you whether a permission is still justified.

Decide each scope switch on its own merits

Go through the permission options one at a time rather than accepting a preset bundle. Read-only access is the natural starting point for monitoring, record-keeping and portfolio tracking. Trading permissions are a separate step, and they deserve their own decision even if you already granted read access to the same tool.

The scopes that let funds leave the account, whether described as withdrawal, transfer or similar wording, are the ones to treat with the most caution. For most beginner use cases there is no reason to enable them, and a script that genuinely needs them should be one you wrote yourself or fully understand. If a setup instruction insists on fund-moving permissions for something that only reads data, stop and verify against the official documentation before continuing.

Some keys also carry options such as binding to a specific IP address or restricting which account types the key can touch. Where such options exist, they narrow what a leaked key can do, so consider them part of the scope decision rather than an afterthought. Confirm the exact current options and their names on the official pages, since interfaces change and this guide cannot list them for you.

Name, store and limit the key before you use it

Give the key a label that identifies the tool and the purpose, not a generic name like key1. If you later run several scripts, a clear label is what lets you revoke the right one without disrupting everything else. Record the date of creation alongside the label in your note.

Store the secret part of the key the way you would store a password: in a password manager or an encrypted store, never in a screenshot, a chat message or a plain text file synced to a shared folder. If the tool asks you to paste the secret into a config file, check where that file lives and who else can read it.

Before you rely on the key, run one small test that exercises only the permission you granted. If the tool needs more scope, you will see the error immediately, while the key is still fresh in your mind and easy to replace. Then set yourself a review date, for example a calendar reminder, so the key does not sit unexamined for years.

Review, rotate and revoke on a schedule

Open your API key list periodically and compare it against your note. For each key, ask whether the tool is still in use, whether the scope still matches the job, and whether the label still makes sense. Keys created for a one-off experiment are the usual candidates for deletion.

Revoke keys you no longer need rather than leaving them dormant, and rotate the ones you keep if you suspect exposure, if you shared a device, or simply as a routine. After revoking or rotating, check that the tool still behaves as expected and update your note with the new date and label.

Keep the official help centre and the fee page within reach for the parts of this workflow that involve costs, such as trading activity generated by a script. This guide does not state fee levels, rate tiers or limits, because those change and depend on your account; read the current figures on the official fee page and record what applies to you before you let automation trade.

Digital assets are volatile and derivatives can amplify losses. This website has no login, wallet connection, deposit form or customer-support chat.

Availability can differ by residence, legal entity and product, so no regional access is assumed from language or branding alone.

Scenario checkpoint

• Write one sentence describing what the software must do, and keep it with the key label.
• Grant read-only access first and add trading scope only if a test proves it is required.
• Leave fund-moving scopes such as withdrawal or transfer disabled unless you fully understand why they are needed.
• Check whether the key can be bound to a specific IP address or limited to certain account types, and use those options where available.
• Store the secret in a password manager, never in screenshots, chats or shared folders.
• Set a review date and revoke or rotate any key whose tool, scope or label no longer matches your note.
