Testing Connections in Batches

Function

This API is used to test connections in batches.

Debugging

You can debug the API in API Explorer to support automatic authentication. API Explorer can automatically generate and debug example SDK code.

Constraints

After the task is created, you can test the connection only when the task status is CONFIGURATION.
In the dual-active DR scenario, the backward task can be executed only when the forward task is in INCRE_TRANSFER_STARTED state. The parent task cannot call the API.
You can call a maximum of 10 APIs in batches.
