License Check and Grace Period

The plugin periodically verifies the license through the Deviking public API.

Caching

License checks are cached so the site does not contact the API for every print operation.

Temporary API errors

A temporary connection problem does not necessarily deactivate a previously valid license immediately.

Grace period

Transient API or network failures can use the built-in grace period before printing is blocked.

Domain validation

A domain mismatch is handled separately from a temporary API outage.
