List all the namespaces under an Azure subscription.

GET https://management.azure.com/subscriptions/{subscriptionId}/providers/Microsoft.EventGrid/namespaces?api-version=2025-02-15

With optional parameters:

GET https://management.azure.com/subscriptions/{subscriptionId}/providers/Microsoft.EventGrid/namespaces?api-version=2025-02-15&$filter={$filter}&$top={$top}

URI Parameters

Name	In	Required	Type	Description
subscriptionId	path	True	string	Subscription credentials that uniquely identify a Microsoft Azure subscription. The subscription ID forms part of the URI for every service call.
api-version	query	True	string	Version of the API to be used with the client request.
$filter	query		string	The query used to filter the search results using OData syntax. Filtering is permitted on the 'name' property only and with limited number of OData operations. These operations are: the 'contains' function as well as the following logical operations: not, and, or, eq (for equal), and ne (for not equal). No arithmetic operations are supported. The following is a valid filter example: $filter=contains(namE, 'PATTERN') and name ne 'PATTERN-1'. The following is not a valid filter example: $filter=location eq 'westus'.
$top	query		integer (int32)	The number of results to return per page for the list operation. Valid range for top parameter is 1 to 100. If not specified, the default number of results to be returned is 20 items per page.
