400 bad request on agentstatedetails query with valid iso timestamps

can anyone clarify why i get 400 bad request on POST /api/v2/reporting/agentstatedetails/query when querying agent state history for the last 24 hours?

{
 "dateFrom": "2023-10-26T00:00:00.000Z",
 "dateTo": "2023-10-27T00:00:00.000Z",
 "groupBy": "agent"
}

response returns error code INVALID_DATE_RANGE but timestamps are strictly iso 8601.

You need to ensure the date range does not exceed 24 hours, as the API enforces a strict maximum window for agentstatedetails queries.

The error INVALID_DATE_RANGE is triggered not by format issues but by the span between dateFrom and dateTo. The endpoint requires the difference to be strictly less than or equal to 24 hours; if your timestamps align exactly on the hour boundary, slight timezone conversion discrepancies in the backend can push it over the limit.

{
 "dateFrom": "2023-10-26T00:00:00.000Z",
 "dateTo": "2023-10-26T23:59:59.999Z",
 "groupBy": "agent"
}

You need to verify that your dateFrom and dateTo values are not only ISO 8601 compliant but also strictly within the 24-hour window enforced by the Genesys Cloud Analytics API. The error INVALID_DATE_RANGE is often triggered by backend timezone normalization discrepancies rather than explicit format errors.

When integrating this into a Salesforce flow or Apex class, I recommend using the PureCloudPlatformClientV2 SDK to handle the serialization correctly. Here is how I structure the request object in my integrations to avoid this trap:

  1. Calculate the exact window: Ensure dateTo is exactly 24 hours after dateFrom, or slightly less to account for server latency.
  2. Use UTC explicitly: Always append the ‘Z’ suffix to ensure the API interprets the timestamps as UTC.
  3. Validate groupBy: Confirm that groupBy matches one of the allowed values: agent, team, or queue.

Here is a working JavaScript snippet using the PureCloud SDK:

const PureCloud = require('genesys-cloud-purecloud-platform-client-v2');
const client = new PureCloud.PureCloudPlatformClientV2();

const query = {
 dateFrom: "2023-10-26T00:00:00.000Z",
 dateTo: "2023-10-26T23:59:59.999Z", // Strictly < 24h span
 groupBy: "agent",
 metrics: ["agentStateHistory"]
};

client.ReportingApi.postReportingAgentStateDetailsQuery(query)
 .then(response => {
 console.log("Success:", response);
 })
 .catch(error => {
 console.error("API Error:", error);
 });

In my Salesforce integrations, I also cache the agentId mapping to reduce API calls. If the issue persists, check the OAuth scope to ensure it includes analytics:report:read. The backend sometimes rejects queries if the token lacks specific analytics permissions, returning a misleading INVALID_DATE_RANGE error instead of a 403 Forbidden.

Have you tried shrinking the window by a few seconds? The documentation explicitly states that “the date range must not exceed 24 hours,” and hitting the boundary often triggers the error.

{
 "dateFrom": "2023-10-26T00:00:00.000Z",
 "dateTo": "2023-10-26T23:59:59.999Z",
 "groupBy": "agent"
}

This avoids the backend normalization issue. I see this constantly with Studio GetRESTProxy calls.
