Hi @Shruti1, Urls used in any campaign delivery will be stored in nms:delivery table and the field will be 'mdata'(sql field). In preview, you might not be able to view the data directly in ACC, however, you can use below query to identify the delivery and you can get campaign details in the additional data.
Query:
Additional data for campaign details:
Add campaign label, internal name etc from the available fields in the linked table(campaign/nms:operation) table.
