Endpoint returns all metered events regardless of mId & bearer token used.
This appears to possibly be a bug, I've created metered events for different mId's and using this endpoint to read metered events always returns all of the created events for the appId.
Here's the reference to the endpoint I'm using:
Get all events for an app metered event type
GET https://sandbox.dev.clover.com/v3/apps/{appId}/merchants/{mId}/metereds/{meteredId}
