QueryToken - ApsaraMQ for MQTT - Alibaba Cloud Documentation Center

Queries the status of a token. If token-based authentication is used for permission authentication on an ApsaraMQ for MQTT broker, a token that is issued by the broker is required for authentication each time a client is connected to the broker. A token is a temporary credential and is valid only within a specific period of time. You can call this operation to query whether a token expires.

Operation description

You can call this operation up to 100 times per second per account. If you want to increase the limit, join the DingTalk group 35228338 to contact ApsaraMQ for MQTT technical support.
Each successful call to the QueryToken operation increases the messaging transactions per second (TPS) by one. This affects the billing of your instance. For more information, see Billing rules.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
