I send a POST command against an API with Invoke-RestMethod. I expect the return value to be a download link that I want to process further. However, this URL is stored in a property whose name changes with each retrieval (in my Example 0bab6b8c-9f30-xxxx-xxxx-ad99957aeae0).

Example:

$query = Invoke-RestMethod @Params

Response:

$query.result.'0bab6b8c-9f30-xxxx-xxxx-ad99957aeae0' | fl *

status     : success
name       : myfile.wav
size       : 508312
source_url : https://xxxxxxxx/0bab6b8c-9f30-xxxx-xxxx-ad99957aeae0
duration   : 2

How do I get to the next property of $query.result with Powershell when I don’t even know the ResponseID?
