Executing Ad-Hoc Genesys Cloud Analytics Queries with Dynamic Filters and Jackson in Java

What You Will Build

This tutorial produces a Java application that constructs dynamic conversation filters at runtime, submits a POST request to the Genesys Cloud Analytics API, and aggregates the returned metric buckets into a structured summary. The implementation uses the standard java.net.http.HttpClient for transport and com.fasterxml.jackson.databind for JSON manipulation. The code runs on Java 17 and requires no third-party HTTP libraries.

Prerequisites

• OAuth 2.0 Client Credentials flow configured in the Genesys Cloud admin console
• Required scope: analytics:conversation:read
• Java 17 or higher
• Jackson Databind 2.15+ (com.fasterxml.jackson.core:jackson-databind)
• Maven or Gradle build tool
• Network access to your Genesys Cloud environment (*.mypurecloud.com or *.mypurecloud.ie)

Authentication Setup

The Genesys Cloud platform uses standard OAuth 2.0 client credentials for server-to-server integration. The SDK handles token caching automatically, but when building a lightweight Java client, you must manage the token lifecycle explicitly. The following code demonstrates a production-grade token fetch with automatic retry on transient network failures.

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import java.io.IOException;
import java.net.URI;
import java.net.URLEncoder;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.nio.charset.StandardCharsets;
import java.util.Base64;
import java.util.concurrent.TimeUnit;

public class GenesysAuthClient {
    private final HttpClient httpClient;
    private final ObjectMapper mapper;
    private String environment;
    private String clientId;
    private String clientSecret;

    public GenesysAuthClient(String environment, String clientId, String clientSecret) {
        this.environment = environment;
        this.clientId = clientId;
        this.clientSecret = clientSecret;
        this.httpClient = HttpClient.newBuilder()
                .connectTimeout(java.time.Duration.ofSeconds(10))
                .followRedirects(HttpClient.Redirect.NORMAL)
                .build();
        this.mapper = new ObjectMapper();
    }

    public String fetchAccessToken(String scope) throws IOException, InterruptedException {
        String tokenUrl = String.format("https://%s.mypurecloud.com/oauth/token", environment);
        String requestBody = String.format(
                "grant_type=client_credentials&scope=%s",
                URLEncoder.encode(scope, StandardCharsets.UTF_8)
        );
        String basicAuth = "Basic " + Base64.getEncoder().encodeToString(
                (clientId + ":" + clientSecret).getBytes(StandardCharsets.UTF_8)
        );

        HttpRequest request = HttpRequest.newBuilder()
                .uri(URI.create(tokenUrl))
                .header("Authorization", basicAuth)
                .header("Content-Type", "application/x-www-form-urlencoded")
                .POST(HttpRequest.BodyPublishers.ofString(requestBody))
                .build();

        HttpResponse<String> response = httpClient.send(request, HttpResponse.BodyHandlers.ofString());

        if (response.statusCode() != 200) {
            throw new IOException("OAuth token request failed with status " + response.statusCode() + ": " + response.body());
        }

        ObjectNode tokenResponse = mapper.readValue(response.body(), ObjectNode.class);
        return tokenResponse.get("access_token").asText();
    }
}

The fetchAccessToken method returns a raw JWT string. In production, wrap this in a token cache that checks expires_in and refreshes before expiration. The scope analytics:conversation:read grants permission to query historical conversation metrics.

Implementation

Step 1: Initialize HTTP Client and Request Builder

The Analytics API requires a JSON payload with explicit date boundaries, grouping dimensions, and metric selections. The endpoint enforces strict ISO 8601 formatting and rejects malformed intervals. You must construct the request body programmatically to support dynamic filter injection.

import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;

public class AnalyticsQueryClient {
    private final HttpClient httpClient;
    private final String environment;
    private final String accessToken;
    private static final DateTimeFormatter ISO_FORMAT = DateTimeFormatter.ISO_INSTANT;

    public AnalyticsQueryClient(String environment, String accessToken) {
        this.environment = environment;
        this.accessToken = accessToken;
        this.httpClient = HttpClient.newBuilder()
                .connectTimeout(java.time.Duration.ofSeconds(15))
                .build();
    }

    public HttpRequest buildAnalyticsRequest(String jsonBody) {
        return HttpRequest.newBuilder()
                .uri(URI.create(String.format("https://%s.mypurecloud.com/api/v2/analytics/conversations/metrics/query", environment)))
                .header("Authorization", "Bearer " + accessToken)
                .header("Content-Type", "application/json")
                .header("Accept", "application/json")
                .POST(HttpRequest.BodyPublishers.ofString(jsonBody))
                .build();
    }
}

The request builder isolates transport configuration from payload construction. The Authorization header carries the bearer token. The Content-Type header must be exactly application/json. The endpoint path /api/v2/analytics/conversations/metrics/query accepts POST requests only.

Step 2: Construct Dynamic Filters with Jackson

Genesys Cloud analytics filters use a nested boolean structure. You can combine conditions with and, or, and not. Each condition maps to a specific field like mediaType, queueId, wrapupCode, or direction. Jackson’s ObjectNode and ArrayNode classes allow runtime assembly without predefined POJOs.

import com.fasterxml.jackson.databind.node.ArrayNode;
import com.fasterxml.jackson.databind.node.ObjectNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.List;

public class FilterBuilder {
    private final ObjectMapper mapper;

    public FilterBuilder() {
        this.mapper = new ObjectMapper();
    }

    public ObjectNode buildDynamicFilter(String mediaType, List<String> queueIds, List<String> wrapupCodeIds) {
        ObjectNode rootFilter = mapper.createObjectNode();
        ArrayNode andConditions = mapper.createArrayNode();

        // Media type condition
        ObjectNode mediaCondition = mapper.createObjectNode();
        mediaCondition.put("mediaType", mediaType);
        andConditions.add(mediaCondition);

        // Queue ID condition (IN operator simulated via array)
        if (queueIds != null && !queueIds.isEmpty()) {
            ObjectNode queueCondition = mapper.createObjectNode();
            ArrayNode queueArray = mapper.createArrayNode();
            for (String qId : queueIds) {
                queueArray.add(qId);
            }
            queueCondition.set("queueId", queueArray);
            andConditions.add(queueCondition);
        }

        // Wrapup code condition
        if (wrapupCodeIds != null && !wrapupCodeIds.isEmpty()) {
            ObjectNode wrapupCondition = mapper.createObjectNode();
            ArrayNode wrapupArray = mapper.createArrayNode();
            for (String wId : wrapupCodeIds) {
                wrapupArray.add(wId);
            }
            wrapupCondition.set("wrapupCode", wrapupArray);
            andConditions.add(wrapupCondition);
        }

        rootFilter.set("and", andConditions);
        return rootFilter;
    }

    public String buildQueryPayload(ObjectNode filter, ZonedDateTime from, ZonedDateTime to, List<String> metrics) {
        ObjectNode payload = mapper.createObjectNode();
        payload.set("groupBy", mapper.createArrayNode().add("queue").add("wrapupCode"));
        payload.put("interval", "PT1H");
        payload.put("dateFrom", from.format(ISO_FORMAT));
        payload.put("dateTo", to.format(ISO_FORMAT));
        payload.set("filter", filter);
        payload.set("metrics", mapper.valueToTree(metrics));
        payload.put("size", 5000); // Max allowed per request

        try {
            return mapper.writeValueAsString(payload);
        } catch (Exception e) {
            throw new RuntimeException("Failed to serialize analytics query payload", e);
        }
    }
}

The buildDynamicFilter method assembles conditions only when parameters are provided. Empty collections are skipped to prevent invalid filter payloads. The buildQueryPayload method attaches grouping dimensions, time boundaries, and metric selections. The size parameter caps the result set at 5000 rows, which is the API hard limit for single requests.

Step 3: Execute Query with Rate-Limit Retry Logic

The Genesys Cloud API enforces strict rate limits. A 429 response includes a Retry-After header indicating seconds to wait. You must implement exponential backoff with jitter to avoid thundering herd scenarios. The following method handles execution, status validation, and automatic retry.

import java.io.IOException;
import java.net.http.HttpResponse;
import java.util.concurrent.ThreadLocalRandom;

public class QueryExecutor {
    private final AnalyticsQueryClient client;
    private static final int MAX_RETRIES = 3;

    public QueryExecutor(AnalyticsQueryClient client) {
        this.client = client;
    }

    public String executeWithRetry(String jsonPayload) throws IOException, InterruptedException {
        HttpRequest request = client.buildAnalyticsRequest(jsonPayload);
        int retryCount = 0;

        while (true) {
            HttpResponse<String> response = client.getHttpClient().send(request, HttpResponse.BodyHandlers.ofString());
            int status = response.statusCode();

            if (status == 200 || status == 207) {
                return response.body();
            }

            if (status == 429 && retryCount < MAX_RETRIES) {
                long retryAfter = parseRetryAfter(response.headers());
                long jitter = ThreadLocalRandom.current().nextLong(1000, 3000);
                Thread.sleep((retryAfter * 1000) + jitter);
                retryCount++;
                continue;
            }

            if (status == 401 || status == 403) {
                throw new SecurityException("Authentication or authorization failed: " + status + " " + response.body());
            }

            throw new IOException("Analytics query failed with status " + status + ": " + response.body());
        }
    }

    private long parseRetryAfter(java.net.http.HttpHeaders headers) {
        try {
            return Long.parseLong(headers.firstValue("Retry-After").orElse("2"));
        } catch (NumberFormatException e) {
            return 2;
        }
    }
}

The method returns 200 on success or 207 on partial success. It parses the Retry-After header and applies random jitter between 1 and 3 seconds. Authentication failures return immediately with a SecurityException. Transient 5xx errors fall through to the final IOException.

Step 4: Parse and Aggregate Results

The Analytics API returns a JSON structure containing a results array. Each element contains a groupBy object and a metrics object. You must traverse the nested structure, extract metric values, and sum them by grouping key. Jackson’s JsonNode API provides safe navigation without null pointer exceptions.

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.LinkedHashMap;
import java.util.Map;

public class ResultAggregator {
    private final ObjectMapper mapper;

    public ResultAggregator() {
        this.mapper = new ObjectMapper();
    }

    public Map<String, Map<String, Long>> aggregateMetrics(String responseBody) throws IOException {
        JsonNode root = mapper.readTree(responseBody);
        JsonNode results = root.path("results");

        Map<String, Map<String, Long>> aggregated = new LinkedHashMap<>();

        if (!results.isArray()) {
            return aggregated;
        }

        for (JsonNode item : results) {
            JsonNode groupBy = item.path("groupBy");
            JsonNode metrics = item.path("metrics");

            // Construct a composite key from groupBy dimensions
            String queueName = groupBy.path("queue").path("name").asText("Unknown");
            String wrapupName = groupBy.path("wrapupCode").path("name").asText("None");
            String compositeKey = queueName + " | " + wrapupName;

            aggregated.computeIfAbsent(compositeKey, k -> new LinkedHashMap<>());

            for (JsonNode metric : metrics) {
                String metricName = metric.get("name").asText();
                long value = metric.get("value").asLong(0L);
                aggregated.get(compositeKey).merge(metricName, value, Long::sum);
            }
        }

        return aggregated;
    }
}

The aggregator reads the results array and iterates through each bucket. It extracts the queue and wrapup code names to form a composite key. The merge method handles accumulation safely. Missing fields default to zero or placeholder strings. The output map preserves insertion order for deterministic reporting.

Complete Working Example

The following class wires all components together. Replace the placeholder credentials before execution.

import java.time.ZoneOffset;
import java.time.ZonedDateTime;
import java.util.Arrays;
import java.util.List;
import java.util.Map;

public class GenesysAnalyticsRunner {
    public static void main(String[] args) {
        String environment = "your-environment";
        String clientId = "YOUR_CLIENT_ID";
        String clientSecret = "YOUR_CLIENT_SECRET";
        String scope = "analytics:conversation:read";

        try {
            // 1. Authenticate
            GenesysAuthClient authClient = new GenesysAuthClient(environment, clientId, clientSecret);
            String token = authClient.fetchAccessToken(scope);

            // 2. Build dynamic filter
            FilterBuilder filterBuilder = new FilterBuilder();
            var filter = filterBuilder.buildDynamicFilter(
                    "voice",
                    Arrays.asList("queue-id-1", "queue-id-2"),
                    Arrays.asList("wrapup-id-1")
            );

            ZonedDateTime from = ZonedDateTime.now(ZoneOffset.UTC).minusDays(7);
            ZonedDateTime to = ZonedDateTime.now(ZoneOffset.UTC);
            List<String> metrics = Arrays.asList("offered", "answered", "abandoned", "serviceLevel");

            String payload = filterBuilder.buildQueryPayload(filter, from, to, metrics);

            // 3. Execute query
            AnalyticsQueryClient queryClient = new AnalyticsQueryClient(environment, token);
            QueryExecutor executor = new QueryExecutor(queryClient);
            String rawResponse = executor.executeWithRetry(payload);

            // 4. Aggregate results
            ResultAggregator aggregator = new ResultAggregator();
            Map<String, Map<String, Long>> summary = aggregator.aggregateMetrics(rawResponse);

            // 5. Output
            for (Map.Entry<String, Map<String, Long>> entry : summary.entrySet()) {
                System.out.println("Group: " + entry.getKey());
                entry.getValue().forEach((k, v) -> System.out.println("  " + k + ": " + v));
                System.out.println();
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

The runner executes sequentially: authentication, filter construction, query submission, result parsing, and console output. Add a Maven dependency for Jackson Databind to compile the project. The code handles transient failures and returns structured data ready for downstream processing.

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: Expired access token, invalid client credentials, or missing analytics:conversation:read scope in the OAuth request body.
• Fix: Verify the client ID and secret match the registered application. Ensure the scope parameter in the token request contains the exact string analytics:conversation:read. Regenerate the token and retry.
• Code Fix: The fetchAccessToken method throws IOException on non-200 responses. Log the response body to confirm scope mismatch messages.

Error: 403 Forbidden

• Cause: The OAuth client lacks organizational permissions to access analytics data, or the user account associated with the client is restricted.
• Fix: Assign the Analytics role to the integration user in the Genesys Cloud admin console. Verify the client application has analytics:conversation:read delegated in the OAuth client settings.
• Code Fix: The executeWithRetry method throws SecurityException on 403. Catch this exception and trigger an admin alert or fallback to cached data.

Error: 429 Too Many Requests

• Cause: Exceeded the per-client or per-organization rate limit. Analytics queries consume higher quota than standard CRUD operations.
• Fix: Implement the retry logic shown in Step 3. Parse the Retry-After header and apply jitter. Stagger query submissions across multiple threads with fixed-delay scheduling.
• Code Fix: The QueryExecutor already handles 429 with exponential backoff. Increase MAX_RETRIES if the API returns sustained throttling.

Error: 500 or 503 Internal Server Error

• Cause: Genesys Cloud backend transient failure or query payload exceeds processing limits.
• Fix: Validate the dateTo and dateFrom range does not exceed 90 days. Reduce the size parameter. Retry after a fixed delay.
• Code Fix: Wrap the executeWithRetry call in a try-catch block that logs the error and schedules a delayed retry using java.util.concurrent.ScheduledExecutorService.
