Exchange API-key rotation replaces a credential while preserving a clear account and order history. For planned rotation, inventory the key's consumers, reconcile open work, create a narrowly scoped replacement for the same account and environment, verify it, and retire the old key at the exchange. For suspected exposure, revoke the affected key immediately; preserving access is secondary to containment.
A rotation is not complete because a new secret was saved. The old credential may still work, an overlooked script may still use it, and the replacement may point to a different account. Meanwhile, an order submitted before the change can still be open.
The useful completion test is more demanding: the intended service uses the intended new authority, the old authority has ended, and every outstanding account action still has an owner. This article walks through that handoff without requiring a live trade as a diagnostic.
Decide whether this is maintenance or an incident
Scheduled retirement and suspected compromise need different sequences. In maintenance, you may be able to prepare a replacement before ending the old credential. In an incident, extending a suspected attacker's access to achieve a smooth handoff is the wrong objective.
OWASP distinguishes creation, rotation, revocation and expiration as separate secret-lifecycle stages. A consumer stopping or deleting its saved copy does not itself revoke the credential at the provider. That distinction is the basis for keeping a separate exchange-side retirement check. OWASP secrets management.
If a key appeared in a public repository, chat, screenshot or untrusted application, use the credential incident response procedure. Do not first test whether someone else can exploit it. Revoke through the venue's official controls, preserve non-secret evidence and inspect the account's exposure.
The rest of this article describes a planned rotation where there is no known exposure. It does not establish a universal rotation interval. A useful interval depends on provider requirements, credential scope, access changes and your ability to perform the handoff reliably.
Inventory consumers before creating another key
A key label such as “main bot” is not an inventory. List every application, script, deployment and person that may still have the credential. A forgotten balance exporter can turn a successful retirement into an unexpected monitoring outage; a forgotten trading process creates a more serious uncertainty.
Keep a non-secret record with the venue, account label, environment, product permissions, permitted request origins, creation date and intended owner. Record where the secret is stored without copying the secret into the inventory itself.
Use one dedicated credential per application where the venue and service support it. That gives retirement a clearer boundary. It does not separate the account's assets: two keys authorized for the same account can affect the same pool of funds. The permission guide explains that distinction.
Before creating a replacement, also check provider limits on active keys, account restrictions and required IP settings. Do not delete a still-needed key merely because the creation screen has reached its limit. First establish how outstanding work will be managed if the application loses access.
Preserve account state, not just connection status
The account exists independently of the credential used to observe it. A new key for the same account does not create new holdings, cancel old orders or remove previous fills. Conversely, a new key for another account cannot explain the original account's open work.
In the reviewed KLINEO implementation, updating credentials clears previous connection-test results and requires a new test. Updates involving trading or recovery references also check whether the replacement can be proven to target the same account and environment. If that cannot be established, the service can refuse the replacement to preserve the original recovery relationship. This is a product boundary, not a recommendation to bypass a conflict by deleting records.
Before changing credentials, review active workflows, open orders, recent fills and positions through the application and exchange. Arrange who will manage remaining exposure during the handoff. If automation is stopped, verify the resulting account state rather than assuming every exchange-held order disappeared.
For any request with uncertain execution, resolve the uncertainty using the order reconciliation guide. Rotation changes access; it does not resolve a missing order response.
A fictional handoff with an unfinished order
Assume a spot account has one buy order for 0.20 units. It has filled 0.18 units and has 0.02 units remaining. Fees are omitted because this example concerns quantity ownership, not profit. The old key and proposed replacement both belong to that same fictional account.
A weak handoff records “bot paused, new key saved.” A stronger one records the exchange order identifier, cumulative filled quantity, remaining quantity, observed status and time. The operator decides whether the outstanding order should remain or be canceled, then checks the resulting state.
| Stage | Hypothetical evidence | Decision it supports |
|---|---|---|
| Before change | Original quantity 0.20; filled 0.18; remaining 0.02 | The account has both an acquired holding and unfinished work |
| After supported pause | Same order observed at the exchange | Stopping local scheduling did not establish cancellation |
| After deliberate cancellation | Final cumulative fill 0.18, remaining order canceled | No replacement order is needed to “recover” the original 0.20 blindly |
| Replacement verification | Same account identity and observed 0.18 holding | New read access refers to the intended account |
| Old-key retirement | Exchange confirms removal of the old credential | That credential should no longer authorize new requests |
The arithmetic is simply 0.18 + 0.02 = 0.20. In a real account, the quantity can change during cancellation. The final exchange observation replaces the earlier snapshot; do not retain 0.18 as a presumed final value if more fills arrived.
Binance Spot documents order queries and cancellation as separate operations. A query provides evidence about an identified order; a cancellation request needs its own outcome and subsequent state review. Binance Spot trading endpoints.
This is a constructed handoff, not evidence that KLINEO supports every order-management action shown for every venue. Use the supported product controls and the exchange's official interface for the actual account.
Verify the replacement in layers
First verify identity: venue, environment and account. Then verify required read access and the intended product permissions. Finally check the application-specific readiness process. An old green badge belongs to the old credential until the new revision is tested.
Keep withdrawal and transfer permissions disabled for the KLINEO connection. A replacement should not acquire broader authority merely because it is convenient to select every checkbox. Confirm the appropriate outbound IP restrictions using the IP allowlist worksheet.
Different providers expose different management interfaces. Bybit documents modifying API-key settings and deleting a key as separate operations, with their own permission requirements. Changing settings is not equivalent to replacing and retiring a secret. This article is not an instruction to grant wallet permissions just to call a management endpoint; use the venue's official account interface when appropriate. Bybit key modification, Bybit key deletion.
Do not send a live order simply to prove that signing works. Begin with a supported read-only test. If the product requires a separate trading-readiness check, follow its documented scope and understand whether it can change account state.
End the old authority explicitly
For a planned overlap, set an owner and an end condition before beginning. An overlap left “for a few days just in case” becomes another credential to protect, and another way an untracked process can continue operating.
After the supported replacement is verified and remaining work has an owner, retire the old key in the exchange's API management interface. Confirm that you removed the intended credential by its private inventory label. Preserve a non-secret record of the retirement time and provider confirmation.
Remove obsolete copies from the consuming systems and secret stores according to their supported procedures. Do not rely on deletion from one application's settings as proof that every copy has gone. If a rotation was triggered by exposure, provider revocation remains the primary boundary even if old copies persist in backups or logs.
A rollback deserves the same care as the forward change. If the new key fails, investigate the cause before reactivating automation. Reusing an old key is inappropriate if it was exposed, expired or deliberately revoked. A recovery plan can instead rely on direct exchange access while the application connection remains inactive.
A completion record another person can review
A practical rotation record answers five questions: which credential ended, which replacement began, what account it targets, what checks succeeded and what open exposure remains. Include observation times. Avoid a broad “all secure” conclusion that the evidence cannot establish.
For KLINEO, the connection policy and venue-specific help should guide the supported credential form. A KuCoin API passphrase is separate from the exchange login password; a Hyperliquid approved API wallet is different from a primary wallet key. Changing the type of credential is a new authorization decision, not a harmless text replacement.
If the application refuses a change because recovery references remain, preserve the connection and seek assistance through the contact page. Never post the secret with the error. Rotation is successful when the account remains understandable after access changes, including when the safe choice is to keep automation paused.
