Errors

api_key_expired

The key passed its expiry date.

HTTP 401authentication_error

The key is correct and nobody revoked it. It has an expiry date, and that date passed.

Why it happens

You can give a key an expiry date when you make it. After that date the key stops. There is no extra time.

How to fix it

Make a new key in Developers → API keys and install it.

You know an expiry date in advance, so set a reminder. If the integration must not stop, make the new key with no expiry date.
