How can tickets be marked for deletion in bulk?

The ability to mark tickets for deletion in bulk is effectively achieved through the use of the bulk delete API. This method allows administrators to manage large numbers of tickets efficiently, which is particularly useful in environments where ticket volumes can be high. By utilizing the API, a user can automate the deletion process for numerous tickets at once, rather than having to handle each ticket individually, which would be time-consuming and inefficient.

Using the bulk delete API streamlines workflows and helps maintain the overall organization of the ticketing system. The other options do not provide a viable means for bulk deletion: the settings menu typically does not include such a feature, checking each ticket individually is impractical for large quantities, and the claim that there is no option for bulk deletion is incorrect in the context of the API's capabilities. This highlights the importance of understanding the tools available within Zendesk for effective ticket management.
