Expired API keys have a talent for surfacing at the worst possible moment. Spark now nudges you before a key expires, so renewals happen on your schedule instead of production's.
Notifications for API key expiry
Don't get caught out by expired API keys again!
We have a new configuration that will send a reminder when an API key is within 30, 14, and 1 day of its expiry date. To receive these reminders, enable this in the refreshed Tenant configuration.
More customization for API call downloads
When downloading a large volume of API calls, we have added some new customization options to limit the amount of data to download in order to reduce file sizes and improve performance.
Metadata only download.
Choose to keep only inputs or outputs depending on the use case.
Select only particular outputs to include in the download.
