Tagging OKX API Keys by Purpose Before You Automate

Most automation problems on OKX do not start with a broken script. They start with one API key that was created for a quick test, then quietly copied into a portfolio rebalancer, a price logger, a withdrawal helper and a spreadsheet importer. Months later, when you want to change permissions or stop one process, you cannot tell which key belongs to which job, so you leave everything enabled. This guide walks through tagging and naming API keys by purpose before you automate, using only the account settings and help centre material that OKX publishes. The goal is not to teach you to trade with code, but to make every key traceable to a specific automation, a specific permission set and a specific review date. You will set up a labelling habit, verify permissions against the actual task, record what each key is allowed to do, and define the conditions under which you revoke it. Treat the naming convention as part of the security setup, not as housekeeping you do later.

Decide the purpose labels before you create the key

Open the API management area in your OKX account settings and read the available permission options before you generate anything. Write down the small number of distinct jobs you actually run: for example a read-only market data collector, an order placer for one strategy, a balance reporter, and a manual test key you keep separate. Give each job a short purpose label that describes the function, not the mood or the moment, such as data-read, order-strategy-a, or report-balance. The label is the first half of the key name; the second half is a date you can sort, written year-month-day. A key named data-read-2025-03-14 tells you instantly what it does and when it entered service.

Do not create a key until you can finish that sentence: this key exists so that a named script can do a named thing. If the answer is that you are not sure yet, you are about to create the exact key that will be impossible to audit later. Decide the label, the permission set and the review date first, then generate the key. Keep the list of labels somewhere you already look often, such as a notes file or a password manager entry, so the convention survives a computer change.

Check the help centre for how OKX describes API key permissions and any restrictions it applies, and match your labels to that vocabulary. Using the platform's own terms for read, trade and withdraw style permissions makes it far easier to compare what you intended with what the key actually shows in the interface. If the wording in the help centre differs from your label, adjust the label rather than inventing a private shorthand that nobody else could interpret.

Create each key with the narrowest permission set for its job

When you generate a key, select only the permissions the labelled job requires. A read-only data collector should not carry trading permission, and a key used to place orders should not carry withdrawal permission unless the automation genuinely moves funds out, which most monitoring and strategy scripts never do. Bind the key to the narrowest scope the interface allows, and if OKX offers an IP restriction, record which address or range you attached and why. Write that decision next to the label in your notes.

Immediately after creation, record four things: the label, the exact permissions you enabled, the IP restriction if any, and the date. Do not paste the secret into a chat message, a public repository or a shared document. Store it in the tool your script reads from, and confirm that the script is the only consumer. If you cannot identify the single consumer of a key, that is a stop condition: revoke it and start again with a defined job.

A common mistake is creating a second key with the same permissions because the first one was inconvenient to find. That duplicates access and doubles the cleanup later. Instead, use the label to locate the original key, and only create a replacement after you have revoked the old one. The help centre explains the revocation steps; follow them in the same session so you never leave two live keys for one job.

Keep a register that maps each key to a script and a review date

Build a simple register with one row per key. Columns that work well are: label, key name as shown in the account, permissions, IP restriction, the script or tool that uses it, the person or machine responsible, the creation date, and the next review date. Keep it outside the exchange, in a file you back up, because the register is your map when the interface shows you a list of keys with similar names.

Set the review date to a fixed interval you will actually honour, and treat it as a real appointment. On that date, open the API management page, compare each live key against the register, and ask three questions. Does this key still have a script that runs? Does the permission set still match the job? Has the person responsible changed? If any answer is no or unclear, revoke the key rather than leaving it dormant. A dormant key with trading permission is the most common leftover in automated setups.

Use the fee page only if your automation depends on trading costs, and if it does, note in the register which official fee page you checked and on what date, because fee structures change and your strategy assumptions should be revisited when they do. Do not copy a number from memory into the register; record the source and the date you read it, and re-check before relying on it.

Retire keys deliberately when a script changes or stops

Every time you edit a script, rename a job or stop using a tool, treat it as a trigger to revisit the key. If the script's permissions need to grow, create a new key with the new permission set and the new purpose label, then revoke the old key once the script is confirmed working with the replacement. If the script is retired, revoke its key the same day and mark the register row as closed with the date.

Watch for the quiet failure mode where a key is shared between two scripts because it was easier than making a second one. When one script is later modified, you cannot tell whether the other still depends on the same permissions. Split the keys by job, even when that means two keys with similar permissions. The extra row in the register is cheaper than an access review you cannot complete.

If something unexpected happens, such as a key appearing that you do not recognise, or a script failing with a permission error you did not expect, stop and investigate before creating workarounds. Check the account's API list and your register side by side, confirm which key the failing script is actually using, and consult the help centre for the correct revocation and regeneration steps. Never solve an access problem by widening permissions on an existing key; create a correctly labelled key for the job instead.

Scenario checkpoint

• Write the purpose label and a sortable date before generating any key, and refuse to create a key you cannot describe in one sentence.
• Enable only the permissions the labelled job needs, and record any IP restriction you attach.
• Log every key in a register with label, permissions, consuming script, owner, creation date and next review date.
• On the review date, confirm the script still runs and the permissions still match, or revoke the key.
• When a script changes or stops, create a new labelled key or revoke the old one the same day, never leaving two live keys for one job.
