Quick question about a recurring HTTP 502 Bad Gateway error when querying call detail records for our APAC BYOC trunks via the Genesys Cloud Data Action API.
The specific endpoint failing is /api/v2/analytics/details/query. This issue appears exclusively for SIP trunk sessions associated with our Singapore and Tokyo BYOC configurations, while standard PSTN and Genesys-managed trunks return data without issue.
Environment details:
- Genesys Cloud Release: R23.05
- SDK Version: Java 6.0.1
- Trunk Count: 15 BYOC trunks across APAC regions
- Query Scope: Last 24 hours, filtered by
routing.mediaType = “voice”
The payload includes standard filters for start/end time and trunk IDs. The 502 response suggests a backend gateway failure rather than a client-side authentication error, as the token remains valid for other analytics endpoints. We suspect this may be related to how the analytics engine processes SIP signaling metadata for BYOC connections in the SG1 region.
Has anyone encountered similar gateway timeouts when pulling high-volume detail records for BYOC trunks? Are there known rate limits or payload size restrictions specific to SIP trunk analytics that might trigger this behavior?
This happens because the asynchronous nature of the Genesys Cloud Analytics API combined with the specific latency characteristics of cross-border BYOC trunk data synchronization. The 502 Bad Gateway error typically indicates that the upstream analytics processing service timed out while waiting for the data aggregation engine to return results. When querying detail records for BYOC trunks in regions like APAC, the system must correlate SIP signaling data with external carrier logs, which introduces additional processing overhead compared to standard PSTN or Genesys-managed trunks. If the query window is too large or the filter complexity is high, the backend worker fails to respond within the gateway’s timeout threshold.
To resolve this, you should implement a pagination strategy with smaller time windows. Instead of querying a full day or week, break the request into 15-minute or 1-hour intervals. Additionally, ensure your OAuth token has the analytics:details:read scope and that your integration handles the x-genesys-cloud-request-id header for debugging purposes. Here is an example of how to structure the request payload to minimize load:
{
"viewId": "call-details",
"dateRange": {
"from": "2023-10-01T00:00:00.000Z",
"to": "2023-10-01T00:15:00.000Z"
},
"groupBy": [
"direction",
"trunkId"
],
"filters": [
{
"dimension": "trunkId",
"operator": "equals",
"value": "your-byoc-trunk-uuid"
}
]
}
Implementing this approach reduces the computational load on the analytics engine and prevents gateway timeouts. You should also monitor the retry-after header if you encounter rate limiting during bulk queries.
- Reduce query time windows to 15-60 minutes
- Verify
analytics:details:read OAuth scope permissions
- Check BYOC trunk synchronization status in Admin > Telephony
- Monitor API rate limits and implement exponential backoff
