# Block cards in bulk

Submit the details to block Managed Cards.

The bulkId returned in the response can subsequently be used to launch the execution of the bulk process through Execute Bulk Process. A submitted bulk process can be managed (executed, accessed, paused, resumed and cancelled) by any Authorised User of the same identity of the user that submits the details.

The status of the bulk process after execution of this operation is set to ‘SUBMITTED’. The execution of the bulk process is launched through the Execute bulk process operation.

The submission of data for a bulk process does not expire but it can be cancelled through Cancel Bulk Process.

The system is configured to accept bulk requests to process up to a maximum of 10,000 bulk operations.

Each individual operation in this bulk will be processed via Block a Managed Card.
