400 Bad Request
{“errors”:[{“message”:“Invalid aggregation query structure. The ‘groupBy’ field must be an array of valid dimension strings.”,“code”:“bad_request”,“status”:“400”}]}
I am trying to build a simple report in Genesys Cloud that shows queue performance broken down by media type. I am using the Analytics API endpoint /api/v2/analytics/queues/schedules to fetch historical data. The documentation for the Analytics API states:
“The request body must include an aggregations object with a groupBy array containing valid dimension keys like ‘queueId’ or ‘mediaType’.”
I have constructed the following JSON payload based on this quote:
{
"aggregations": {
"groupBy": ["queueId", "mediaType"],
"metrics": ["serviceLevelPercent", "avgHandleTime"]
},
"dateRange": {
"start": "2023-10-01T00:00:00.000Z",
"end": "2023-10-31T23:59:59.999Z"
},
"interval": "P1D"
}
When I send this via POST, I get the 400 error above. The docs clearly list mediaType as a valid dimension for queue analytics. I have verified that the queueId values in my system are valid UUIDs. I am using the Python SDK genesys_cloud_platform_client_v2 but the error persists even when I make a raw HTTP request via Postman.
Is there a specific syntax for combining these dimensions? The error message is generic and does not specify which part of the array is invalid. I have tried swapping the order of the items in the groupBy array, but the result is identical. I am confused because the schema definition in the Swagger UI seems to allow a simple string array. Is there a hidden requirement for the metrics object to align with the groupBy dimensions? I need this data to feed into a simple Architect Data Action, so I cannot use the complex reporting UI exports. Please explain why this valid-looking JSON fails.
the documentation actually says groupBy requires an array of strings, not objects. try ["queue","mediaType"] instead of nested structures.
This looks like a straightforward schema mismatch, but you also need to ensure your groupBy dimensions align with the selected metrics.
- Use
["queue", "mediaType"] as a flat string array.
- Verify that your
metrics array only includes attributes compatible with that grouping (e.g., handleTime, waitTime).
- Check the
filter object for any conflicting constraints that might render the query invalid.

The easiest way to fix this is to ensure your groupBy array only contains dimensions valid for the queues endpoint, as mediaType is often restricted or requires specific metric alignments that trigger this 400. Try isolating queue first to validate the base query structure before adding complex groupings.
It depends, but generally… The suggestion above is technically correct but misses the real pain point. Architect’s JSON parser chokes on nested function calls because it tries to evaluate the string before the API actually processes it, which is exactly why you are seeing that 400. I deal with similar serialization headaches in React Native when mapping WebSocket payloads, so I know how frustrating schema mismatches are. You need to ensure the groupBy array is strictly flat strings like ["queue", "mediaType"] and not wrapped in objects. Also, verify your metrics align with those dimensions. Here is a working curl payload to test:
curl -X POST "https://api.mypurecloud.com/api/v2/analytics/queues/schedules" \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{
"interval": "P7D",
"groupBy": ["queue", "mediaType"],
"metrics": ["handleTime", "waitTime"]
}'
If you still get a 400, check if mediaType is actually supported for your specific queue view, as some endpoints restrict it.
