ServiceUnavailableException reference
The exception that is thrown when an external service that is being requested is not available.
This exception allows extension developers to notify Sana Commerce Cloud that the external service used by the extension is not available at the moment. Sana Commerce Cloud may have a mechanism to notify shop administrators when the extension becomes unavailable.
Note
Sana Commerce Cloud does not catch this exception type when calling any extension method. To decide whether it should be considered during add-on development, check an appropriate "Create new extension" guide.
