Azure Queue Storage

Connect to your Azure Queue Storage to create, query, delete queue entries and queues.

This article describes the operations for the Azure Queue Storage built-in connector, which is available only for Standard workflows in single-tenant Azure Logic Apps. If you're looking for the Azure Table Storage managed connector operations instead, see Azure Queue Storage managed connector reference.

Built-in connector settings

In a Standard logic app resource, the Azure Queue Storage built-in connector includes settings that control various thresholds for performance, timeout, execution time, and so on. For example, you can change the timeout value for queue storage requests from the Azure Logic Apps runtime. For more information, review Reference for host settings - host.json - Table and queue storage.
