Query Assets (Feature Service/Layer)

• URL:https://<featurelayer-url>/queryAssets
  
• Version Introduced:11.1

Description

The queryAssets operation is used to retrieve either multiple assets or asset references. If the assets are small (that is, extruded footprints), it may be more efficient for the client to request multiple assets to be embedded in the response instead of requesting the asset resources individually.

Request parameters

Parameter	Details
assetHashes	An array of SHA256 hashes associated with the assets that the client is requesting information about. Syntax assetHashes=["<assetHash1>","<assetHash2>"] Example assetHashes=["045ef29d382f1c8227bde3a25d37f7a62fe0d2259a3a14dd6486ee53c8faba18"]
transportType	Specifies how the assets will be retrieved. When transportType is set to esriTransportTypeUrl, the response will return asset references. When transportType is set to esriTransportTypeEmbedded, the response will return multiple assets. The default value is esriTransportTypeUrl. Values: esriTransportTypeUrl | esriTransportTypeEmbedded
f	The response format. The default response format is html. Values: html | json | pjson
