Just noticed that the agentStateHistory endpoint keeps returning empty results even though I know agents were logged in.
To retrieve agent state history, query the agentStateHistory resource with a time range filter.
Here’s the fetch call:
const res = await fetch('https://api.nice.incontact.com/ccapi/v2/reporting/agentStateHistory?$filter=timestamp ge 2023-10-27T00:00:00Z and timestamp le 2023-10-27T23:59:59Z', {
headers: { 'Authorization': `Bearer ${token}` }
});
Getting a 200 OK but the items array is null. Am I missing a specific header or is the filter syntax wrong for this version?
Have you tried checking the query syntax? the filter string is malformed. see https://support.nice.com/articles/12345
If I remember correctly… you’re missing the quotes around the datetime strings in the OData filter. try this instead.
{
"filter": "timestamp ge '2023-10-27T00:00:00Z'"
}
var client = new PureCloudPlatformClientV2();
client.AuthClient.SetCredentials(new ApiCredentials { ClientId = “your_id”, ClientSecret = “your_secret” });
var api = new ReportingApi(client);
var result = await api.GetReportingAgentStateHistoryAsync(
from: “2023-10-27T00:00:00Z”,
to: “2023-10-27T23:59:59Z”,
pageSize: 250
);
It depends, but generally... the filter syntax in the previous posts is half-right but misses the full OData requirement for the NICE CXone API. the docs say “OData filters require quoted string literals for datetime values.” you got the quotes, which is good, but you're missing the `to` parameter or the upper bound in the filter string if you're building a raw query. also, make sure you're hitting the correct tenant URL. if you're on `api.nice.incontact.com`, that's legacy. most of us moved to `api.mynicecx.com` or the regional endpoints.
i ran into this exact issue last week. the agent state history endpoint is picky about the time range. if the `from` and `to` are more than 24 hours apart, it returns empty or throws a 400. you have to chunk it. in my C# integration, i use a loop to fetch 24-hour chunks.
also, check your OAuth scopes. you need `reporting:agent-state-history:read`. if you're using a service account, verify it has access to the specific users or queues you're querying. the API doesn't return data for agents the service account can't see.
the `pageSize` parameter is also critical. if you don't set it, the default might be small, and you'll miss data if you're not paging through `nextPageUri`. i always set it to 250 to balance performance and data volume.
if you're still seeing empty results, try querying for a single agent by ID first. `agentId eq 'uuid-here'`. this isolates whether it's a permission issue or a time range issue.
don't forget to handle the `429 Too Many Requests` error. the reporting API has strict rate limits. i use a simple retry policy with exponential backoff in my Azure Functions.
it's frustrating when the docs don't mention these edge cases. i usually just copy-paste the example from the swagger editor and tweak it. if the above doesn't work, check the response headers for hints. sometimes the `x-error-code` header tells you exactly what's wrong.
Make sure you’re using the correct API base URL. Cause: CXone and Genesys Cloud APIs are separate endpoints. Solution: Switch to the Genesys Cloud Reporting API.
from PureCloudPlatformClientV2 import ReportingApi
api = ReportingApi()
api.get_reporting_agentstatehistory(from_date='2023-10-27T00:00:00Z', to_date='2023-10-27T23:59:59Z')
