Querying Attachments

Function

This API is used to query the attachments of the enterprise router.

Constraints

  • Filtering query is supported. The filtering criteria include state, resource_type, and resource_id. You can query multiple resources at a time or use combined criteria to query resources.

  • Pagination query is supported. You can use limit and marker together for pagination query.

  • Only sorting by a single field (id, name, description, created_at, or updated_at) is supported.
