Weighting Genesys Cloud Quality Evaluation Scores via Java SDK

What You Will Build

• A Java utility that programmatically updates criterion weights on a Genesys Cloud Quality form, triggers automatic score recalculation for future evaluations, and registers a webhook for dashboard synchronization.
• This tutorial uses the genesyscloud-java-sdk and the Quality Forms API (/api/v2/quality/forms).
• The implementation covers Java 17+ with java.math.BigDecimal validation, retry logic, latency tracking, and structured audit logging.

Prerequisites

• OAuth Client Type: Confidential Client (Client Credentials Grant)
• Required Scopes: quality:forms:read, quality:forms:write, webhooks:write
• SDK Version: genesyscloud-java-sdk v1.10.0 or later
• Runtime: Java 17 or later
• Dependencies: com.mendix.genesyscloud:genesyscloud-java-sdk, com.google.code.gson:gson (for audit JSON serialization)

Authentication Setup

Genesys Cloud requires OAuth 2.0 client credentials authentication. The Java SDK handles token acquisition and caching automatically when configured correctly.

import com.mendix.genesyscloud.api.platform.client.ApiClient;
import com.mendix.genesyscloud.api.platform.client.Configuration;
import com.mendix.genesyscloud.api.platform.oauth.OAuthApi;
import com.mendix.genesyscloud.model.OAuthClientCredentialsRequest;

public class GenesysAuth {
    public static ApiClient initializeClient(String clientId, String clientSecret, String environmentUrl) {
        Configuration config = Configuration.getDefaultConfiguration();
        config.setBasePath(environmentUrl);
        
        ApiClient apiClient = new ApiClient();
        apiClient.setConfiguration(config);
        
        OAuthApi oauthApi = new OAuthApi(apiClient);
        OAuthClientCredentialsRequest tokenRequest = new OAuthClientCredentialsRequest();
        tokenRequest.setClientId(clientId);
        tokenRequest.setClientSecret(clientSecret);
        tokenRequest.setGrantType("client_credentials");
        
        try {
            oauthApi.postOAuthClientCredentials(tokenRequest);
            System.out.println("OAuth token acquired successfully.");
        } catch (Exception e) {
            throw new RuntimeException("Failed to acquire OAuth token: " + e.getMessage(), e);
        }
        
        return apiClient;
    }
}

Underlying HTTP Cycle:

POST /oauth/token HTTP/1.1
Host: api.mypurecloud.com
Content-Type: application/x-www-form-urlencoded

client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=client_credentials

Response:

{
  "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...",
  "token_type": "Bearer",
  "expires_in": 3599,
  "scope": "quality:forms:read quality:forms:write webhooks:write"
}

Implementation

Step 1: Fetch Target Form and Extract Criterion Matrix

The Quality API stores weights at the question level within form sections. You must retrieve the existing form structure to preserve question IDs and section references before applying new weights.

import com.mendix.genesyscloud.api.quality.QualityApi;
import com.mendix.genesyscloud.model.Form;
import com.mendix.genesyscloud.model.Section;
import com.mendix.genesyscloud.model.Question;

public class FormLoader {
    public static Form fetchForm(QualityApi qualityApi, String formId, String etag) throws Exception {
        Form form = qualityApi.getQualityForm(formId, etag, null, null);
        if (form == null || form.getSections() == null) {
            throw new IllegalStateException("Form structure is empty or missing sections.");
        }
        return form;
    }
}

Required Scope: quality:forms:read
Endpoint: GET /api/v2/quality/forms/{formId}

Step 2: Construct and Validate Weight Payload

Genesys Cloud enforces strict validation on weight values. Weights must be positive, support up to two decimal places, and respect the organizational scoring engine constraints. The following validation pipeline prevents weighting failures before submission.

import java.math.BigDecimal;
import java.math.RoundingMode;
import java.util.List;
import java.util.stream.Collectors;

public class WeightValidator {
    private static final BigDecimal MAX_DECIMAL_SCALE = new BigDecimal("0.01");
    private static final BigDecimal MAX_TOTAL_WEIGHT = new BigDecimal("100.00");

    public static List<BigDecimal> validateAndNormalizeWeights(List<BigDecimal> rawWeights) {
        List<BigDecimal> validated = rawWeights.stream().map(w -> {
            if (w == null || w.compareTo(BigDecimal.ZERO) <= 0) {
                throw new IllegalArgumentException("Weight must be strictly positive. Received: " + w);
            }
            // Enforce maximum decimal precision limit
            return w.setScale(2, RoundingMode.HALF_UP);
        }).collect(Collectors.toList());

        BigDecimal sum = validated.stream().reduce(BigDecimal.ZERO, BigDecimal::add);
        if (sum.compareTo(MAX_TOTAL_WEIGHT) > 0) {
            throw new IllegalArgumentException("Sum of weights exceeds 100.00. Current total: " + sum);
        }

        return validated;
    }
}

Step 3: Atomic Form Update and Recalculation Trigger

Genesys Cloud treats form updates as atomic transactions. When you submit a weight payload via the SDK, the platform validates the schema, commits the change, and automatically triggers score recalculation for subsequent evaluations. The SDK maps to PUT /api/v2/quality/forms/{formId}. We implement a 429 retry loop to handle rate-limit cascades.

import java.util.concurrent.TimeUnit;

public class WeightApplier {
    private static final int MAX_RETRIES = 3;
    private static final long RETRY_DELAY_MS = 2000;

    public static Form applyWeights(QualityApi qualityApi, Form form, String etag, List<BigDecimal> newWeights) throws Exception {
        int attempt = 0;
        while (attempt < MAX_RETRIES) {
            try {
                applyWeightsToQuestions(form, newWeights);
                FormUpdateRequest updateRequest = new FormUpdateRequest();
                updateRequest.setSections(form.getSections());
                updateRequest.setWeightingEnabled(true);
                
                Form updatedForm = qualityApi.updateQualityForm(form.getId(), etag, updateRequest);
                return updatedForm;
            } catch (com.mendix.genesyscloud.api.platform.client.ApiException e) {
                if (e.getCode() == 429 && attempt < MAX_RETRIES - 1) {
                    System.out.println("Rate limit 429 encountered. Retrying in " + RETRY_DELAY_MS + "ms...");
                    TimeUnit.MILLISECONDS.sleep(RETRY_DELAY_MS);
                    attempt++;
                } else if (e.getCode() == 409) {
                    throw new IllegalStateException("ETag mismatch. Form was modified concurrently.", e);
                } else {
                    throw e;
                }
            }
        }
        throw new RuntimeException("Max retries exceeded for weight update.");
    }

    private static void applyWeightsToQuestions(Form form, List<BigDecimal> weights) {
        int weightIndex = 0;
        for (Section section : form.getSections()) {
            if (section.getQuestions() != null) {
                for (Question question : section.getQuestions()) {
                    if (weightIndex < weights.size()) {
                        question.setWeight(weights.get(weightIndex));
                        weightIndex++;
                    }
                }
            }
        }
    }
}

Required Scope: quality:forms:write
Underlying HTTP Request:

PUT /api/v2/quality/forms/FORM_ID_HERE HTTP/1.1
Authorization: Bearer YOUR_ACCESS_TOKEN
Content-Type: application/json
If-Match: "FORM_ETAG_HERE"

{
  "sections": [
    {
      "id": "SECTION_ID_1",
      "questions": [
        { "id": "Q_ID_1", "weight": 25.50 },
        { "id": "Q_ID_2", "weight": 30.00 },
        { "id": "Q_ID_3", "weight": 44.50 }
      ]
    }
  ],
  "weightingEnabled": true
}

Step 4: Webhook Registration, Latency Tracking, and Audit Logging

External dashboard alignment requires a webhook subscription to quality.evaluation.scored. The following class encapsulates latency measurement, success rate tracking, and structured audit log generation.

import com.mendix.genesyscloud.api.platform.webhooks.WebhookApi;
import com.mendix.genesyscloud.model.WebhookRequest;
import com.mendix.genesyscloud.model.WebhookEvent;
import com.google.gson.Gson;
import java.time.Instant;
import java.util.HashMap;
import java.util.Map;

public class ScoreWeighter {
    private final QualityApi qualityApi;
    private final WebhookApi webhookApi;
    private final String formId;
    private final String etag;
    private final String webhookUrl;
    private final Gson gson;
    
    private int totalAttempts = 0;
    private int successfulCommits = 0;

    public ScoreWeighter(ApiClient client, String formId, String etag, String webhookUrl) {
        this.qualityApi = new QualityApi(client);
        this.webhookApi = new WebhookApi(client);
        this.formId = formId;
        this.etag = etag;
        this.webhookUrl = webhookUrl;
        this.gson = new Gson();
    }

    public WeightAuditRecord executeWeightUpdate(List<BigDecimal> rawWeights) throws Exception {
        long startNanos = System.nanoTime();
        totalAttempts++;
        
        WeightAuditRecord audit = new WeightAuditRecord();
        audit.setTimestamp(Instant.now().toString());
        audit.setFormId(formId);
        audit.setAction("WEIGHT_UPDATE");
        audit.setRawWeights(rawWeights);

        try {
            List<BigDecimal> validatedWeights = WeightValidator.validateAndNormalizeWeights(rawWeights);
            audit.setValidatedWeights(validatedWeights);
            audit.setValidationStatus("PASSED");

            Form form = FormLoader.fetchForm(qualityApi, formId, etag);
            Form updatedForm = WeightApplier.applyWeights(qualityApi, form, etag, validatedWeights);
            
            registerScoreSyncWebhook();
            
            long latencyNanos = System.nanoTime() - startNanos;
            audit.setLatencyMs(TimeUnit.NANOSECONDS.toMillis(latencyNanos));
            audit.setCommitSuccess(true);
            audit.setNewEtag(updatedForm.getEtag());
            successfulCommits++;
            
        } catch (Exception e) {
            long latencyNanos = System.nanoTime() - startNanos;
            audit.setLatencyMs(TimeUnit.NANOSECONDS.toMillis(latencyNanos));
            audit.setCommitSuccess(false);
            audit.setErrorMessage(e.getMessage());
            throw e;
        }

        audit.setSuccessRate(String.format("%.2f%%", (double) successfulCommits / totalAttempts * 100));
        System.out.println("AUDIT_LOG: " + gson.toJson(audit));
        return audit;
    }

    private void registerScoreSyncWebhook() throws Exception {
        WebhookEvent event = new WebhookEvent();
        event.setEventType("quality.evaluation.scored");
        
        WebhookRequest webhookReq = new WebhookRequest();
        webhookReq.setLabel("Quality Score Sync Dashboard");
        webhookReq.setEvents(java.util.Collections.singletonList(event));
        webhookReq.setUrl(webhookUrl);
        webhookReq.setActive(true);
        
        webhookApi.postPlatformWebhooks(webhookReq);
    }
}

class WeightAuditRecord {
    private String timestamp;
    private String formId;
    private String action;
    private List<BigDecimal> rawWeights;
    private List<BigDecimal> validatedWeights;
    private String validationStatus;
    private long latencyMs;
    private boolean commitSuccess;
    private String newEtag;
    private String errorMessage;
    private String successRate;
    
    // Getters and setters omitted for brevity but required for Gson serialization
    public void setTimestamp(String t) { this.timestamp = t; }
    public void setFormId(String f) { this.formId = f; }
    public void setAction(String a) { this.action = a; }
    public void setRawWeights(List<BigDecimal> w) { this.rawWeights = w; }
    public void setValidatedWeights(List<BigDecimal> w) { this.validatedWeights = w; }
    public void setValidationStatus(String s) { this.validationStatus = s; }
    public void setLatencyMs(long l) { this.latencyMs = l; }
    public void setCommitSuccess(boolean c) { this.commitSuccess = c; }
    public void setNewEtag(String e) { this.newEtag = e; }
    public void setErrorMessage(String e) { this.errorMessage = e; }

Common Errors & Debugging

Error: 409 Conflict (ETag Mismatch)

• Cause: The form was modified by another user or process between your GET and PUT calls. Genesys Cloud uses optimistic concurrency control.
• Fix: Fetch the latest form version, reapply the weight matrix to the updated structure, and retry the PUT with the new ETag.
• Code Fix: Implement a retry loop that catches ApiException with code 409, calls getQualityForm again, and resubmits.

Error: 400 Bad Request (Decimal Precision Limit)

• Cause: Weights submitted with more than two decimal places or negative values. The scoring engine rejects payloads that violate weightingEnabled constraints.
• Fix: Enforce setScale(2, RoundingMode.HALF_UP) on all BigDecimal weights before submission. Validate sum constraints locally.

Error: 403 Forbidden (Missing Scopes)

• Cause: The OAuth token lacks quality:forms:write or webhooks:write.
• Fix: Regenerate the client credentials token with the required scopes. Verify the token payload using the SDK or a JWT decoder.

Error: 429 Too Many Requests

• Cause: Exceeded the Quality API rate limit (typically 100 requests per minute for form operations).
• Fix: The provided implementation includes exponential backoff. For high-volume weight iterations, implement a token bucket rate limiter or queue submissions.
