## Engineering request
The customer is claiming that this command uses a GET api call which results in an "invalid method" error. When the customer manually changed the API call to POST, it worked. Please confirm that this command works correctly.

**Title:**
az datashare share-subscription list-synchronization | Microsoft Learn

**Verbatim:**
I'll state again. This command appears throws an API error flagging GET as an invalid method. The REST API documentation for this states POST. I tried the API directly and POST does work
