Query Parameters

space_id

string

Filter search results to a particular space ID A universally unique identifier (base64-encoded opaque string).

Example:

"RW50aXR5OjEyMzQ1"

space_name

string

Case-insensitive substring filter on the space name. Narrows results to resources in spaces whose name contains the given string. If omitted, no space name filtering is applied and all resources are returned.

Maximum string length: 255

name

string

Case-insensitive substring filter on the resource name. Returns only resources whose name contains the given string. For example, name=prod matches "production", "my-prod-dataset", etc. If omitted, no name filtering is applied and all resources are returned.

Maximum string length: 255

project_id

string

Filter results to resources associated with a specific project (base64 identifier). If omitted, results are not filtered by project.

A universally unique identifier (base64-encoded opaque string).

Example:

"RW50aXR5OjEyMzQ1"
