Query Domains (Feature Service)

URL:: https://<root>/<serviceName>/FeatureServer/queryDomains
Methods:: GET
Version Introduced:: 10.5

Description

The queryDomains operation processes an array of layer IDs for a feature service and returns the full domain information for domains referenced by those layers. Support for this operation in indicated when the feature service has the supportsQueryDomains property set to true .

This operation can be used by clients to efficiently work with domains. For example, a client can use the queryDomains operation once to get and cache domain information. Clients can then set the returnDomainNames parameter as true on a feature layer resource to get just the domain names from the layer. The domain names returned from the feature layer resource can then be used to find the full domain information in the cache.
