Required. The name of the container asset to list.parentis of the format "projects/*" or "projects/*/assets/**" (e.g., "projects/[PROJECT]" or "projects/earthengine-legacy/assets/users/[USER]/[ASSET]"). All user-owned assets are currently under the project "earthengine-legacy" (e.g., "projects/earthengine-legacy/assets/users/foo/bar"). All other assets are under the project "earthengine-public" (e.g., "projects/earthengine-public/assets/LANDSAT"). If "projects/earthengine-legacy" is specified, the response will consist of a list of all top-level folders owned by the requesting user.
Authorization requires one or more of the followingIAMpermissions on the specified resourceparent:
earthengine.assets.get
earthengine.assets.list
Query parameters
Parameters
pageSize
integer
The maximum number of results per page. The server may return fewer assets than requested. If unspecified, the page size default depends on the EarthEngineAssetView, with higher limits for more restrictive views.
pageToken
string
A token identifying a page of results the server should return. Typically this is the value ofListAssetsResponse.next_page_tokenreturned from the previous call to theassets.listAssetsmethod.
filter
string
If present, specifies a filter. Filters are only applied toImageCollectionassets and are ignored forFolderassets.
The fieldsstartTime,endTime, and members ofpropertiesare recognized. The custom functionintersects(str)is available, which allows filtering by geometry.
An example date filter:
"startTime>\"2020-01-01T00:00:00+00:00\" AND
endTime<\"2020-02-01T00:00:00+00:00\""
Specifies which parts of theEarthEngineAssetresource should be returned in the response. Only applies toImageCollectionassets. All elements ofFolderassets will be encoded in theBASICview regardless of the value of this field.
Request body
The request body must be empty.
Response body
If successful, the response body contains an instance ofListAssetsResponse.
