Real-time Analytics API Queue Wait Time Calculation Issue

General Discussion

How does the real-time analytics API actually calculate queue wait times when the GET /api/v2/analytics/report/real-time endpoint loses data? SDK version 2.14.0 keeps returning null for wait_time field, and it’s throwing a vague timeout error 408 that doesn’t point to any specific module.

NICE usually fills those gaps with estimates, Five9 drops the record completely, and Talkdesk caches the state, while Genesys takes a balanced middle path that still breaks our reporting. Sorry for the newbie question, the docs don’t explain the exact failure reason clearly.

const routingApi = new platformClient.RoutingApi();
const metrics = await routingApi.postRoutingQueuesQueueIdAnalyticsRealtime(
 queueId,
 {
 interval: 'PT1S',
 metrics: ['wait_time', 'talk_time'],
 groupBy: 'interval'
 }
);

You might want to adjust the INTERVAL setting before calling the endpoint. It’s usually the default aggregation window that skips sub-second updates, which causes the WAIT_TIME field to return null during peak routing loads. I typically handle this inside an Architect FLOW by setting a DATA ACTION to poll every two seconds instead of relying on the standard SDK callback. Please verify your OAuth SCOPES include view:queue and view:analytics, otherwise the gateway drops the packet with a 408. The timeout typically points to a missing METRIC FILTER rather than an actual network failure. Network logs usually show nothing. Payload structure tends to hide the issue. Just check it.

The real-time endpoint doesn’t cache intervals like that. You’ll hit a 408 Gateway Timeout when the EventBridge webhook drops the payload before the Lambda Data Action processes it. Try overriding the request_timeout in your CloudFormation stack instead:

Parameters:
 RequestTimeout: 60

Logs just show {"error": "upstream..." anyway. The routing queue state never syncs properly.

the interval tweak worked, but the real fix was patching the codegen template since it was stripping the wait_time property on spec mismatch. forcing the generator to pull the latest routing-queue-realtime spec and overriding the model serializer in the config actually fixed it. now the 408 timeout vanishes because the client stops retrying a malformed payload. the PureCloudPlatformClientV2 flow was fine, it’s just the openapi generator dropping the read_only: true flag on the response schema. here’s the exact override you’ll need to drop into your openapi-generator-config.yaml to keep the field from getting nullified during build:

generatorName: node
additionalProperties:
 useSingleRequestParameter: true
 supportsES6: true
 npmName: "genesys-cloud-custom-client"
modelPackage: models
operations:
 /api/v2/routing/queues/{queueId}/analytics/realtime:
 parameters:
 - in: body
 name: body
 required: true
 schema:
 type: object
 properties:
 interval:
 type: string
 example: "PT1S"
 metrics:
 type: array
 items:
 type: string
 enum: ["wait_time", "talk_time", "handle_time"]
 groupBy:
 type: string
 enum: ["interval"]

run npx @openapitools/openapi-generator-cli generate after that and the nulls disappear. the will actually parse the metric payload instead of choking on the default aggregation window. you’ll also want to pass scope: ["analytics:read", "routing:analytics:read"] during the oauth handshake so the gateway doesn’t drop the request before it hits the lambda layer anyway.
