API key expiry monitoring

API key expiry monitoring so an integration doesn't break without warning

An API key or access token that quietly expires doesn't announce itself — it shows up as a support ticket, a failed webhook, or a job that's been silently failing since 2am. API key expiry monitoring keeps a date on every key that has one, so the expiry is expected instead of discovered.

Why API keys are easy to lose track of

Unlike a domain or a certificate, there's no independent, public place to check whether an API key or token is close to expiring — the expiry date exists only inside the provider's dashboard, if the provider shows one at all. Keys also tend to get created in the moment, by whoever is setting up an integration, and rarely make it onto any list afterward.

The failure mode is also harder to diagnose than most. A certificate expiring produces an obvious browser warning; an expired API key produces a generic authentication error that could mean a dozen different things, on a system that might not be the first place anyone looks. The gap between "it broke" and "it broke because the key expired three days ago" is often the most expensive part of the incident.

What API key expiry monitoring should do

The details that turn a scattered set of tokens into something a team can actually stay ahead of.

A record of every key with an expiry

Not every key expires, but the ones that do need to be listed somewhere other than the provider's dashboard and whoever set them up.

The expiry date, not the secret

Tracking needs to know when a key expires without ever needing to store the key itself.

A warning before the integration breaks

The useful moment to act is before the key stops working, with enough time to generate and roll in a replacement.

Grouped with what the key belongs to

A key tracked next to the service or integration it authenticates is far more useful than one in a list with no context.

Shared, so it's not one engineer's memory

Whoever created the key is often not the person who'll be on call when it expires.

No special treatment needed for how odd the expiry is

Some keys last 30 days, some last a year — the system tracking them shouldn't care which.

How RenewKeeper tracks API key expiry

A record of every key
API key or token is one of ten built-in categories, so every key with an expiry gets a place on the list.
The date, not the secret
There's no field for a secret anywhere in RenewKeeper. You record the name, category, and expiry date — never the key value itself.
A warning before it breaks
Alerts and the weekly digest are included on every plan, so the warning arrives while there's time to rotate the key.
Grouped with context
Notes and a renewal URL can be added to an item, so a key sits with a reminder of which integration it belongs to and where to regenerate it.
Shared visibility
A Space can be shared with the rest of the team, so an API key's expiry isn't known only to whoever created it.
No special handling required
A key expiring in 30 days and one expiring in a year are both just an item with a date — the alerts and digest work the same way regardless.

Who this is for

Developers

Anyone who's had an integration fail in production because a token expired with no warning.

IT & ops teams

Third-party and internal API credentials tracked alongside the certificates and domains they sit next to.

Agencies building integrations

Client projects that use several third-party APIs, each with its own key and its own expiry policy.

Common questions

What is API key expiry monitoring?
It's keeping a list of every API key or access token that has an expiry date, with a warning sent before that date arrives, so an integration failing from an expired key is expected and fixed in advance rather than discovered as an outage.
Does it store the API key itself?
No. RenewKeeper has no field for a secret anywhere in the app. You record that a key exists, what it's for, and when it expires — never the key value, so there's nothing sensitive sitting in the tracker to be a target.
How does it know when a key expires if there's no public record?
You enter the expiry date once, the same way you would for a software licence, using the date the provider shows in its own dashboard. From then on it gets the same alerts and weekly digest as anything else tracked.
Can I track keys for different services in one place?
Yes. API key or token is a built-in category, and each item can carry notes and a link, so a key for one provider sits in the same list as keys for every other service, with enough context to know what each one is for.
Is there a free way to track API key expiry?
RenewKeeper's free plan tracks up to 10 items in one Space, with no card required and no time limit, and alerts are included on every plan.
