Triggering Genesys Cloud Agent Assist Screen Pop Events via Java SDK

What You Will Build

A Java service that programmatically triggers incoming call screen pop events using the Genesys Cloud Agent Assist API, validates payloads against assist constraints, manages window focus via WebSocket operations, synchronizes with external CRM plugins, and tracks latency and audit metrics. This tutorial uses the official Genesys Cloud Java SDK and the REST API surface. The implementation covers Java 17.

Prerequisites

• OAuth 2.0 client credentials flow with agentassist:trigger, agentassist:read, platform:read, and webhook:read scopes
• Genesys Cloud Java SDK v2.100.0 or later
• Java 17 runtime environment
• Maven dependencies: genesyscloud-java-sdk, jackson-databind, slf4j-api, java.net.http (built into Java 17)
• Active Genesys Cloud organization with Agent Assist enabled and screen pop destinations configured

Authentication Setup

Genesys Cloud APIs require OAuth 2.0 Bearer tokens. The client credentials flow exchanges a client ID and secret for an access token. You must cache the token and implement refresh logic before expiration to prevent 401 interruptions.

import com.mypurecloud.api.ClientConfiguration;
import com.mypurecloud.api.auth.OAuthApi;
import com.mypurecloud.api.auth.ClientCredentialsRequest;
import com.mypurecloud.api.auth.OAuthTokenResponse;
import java.time.Instant;
import java.util.concurrent.ConcurrentHashMap;

public class GenesysAuthManager {
    private static final String API_BASE_URL = "https://api.mypurecloud.com";
    private final String clientId;
    private final String clientSecret;
    private final String region;
    private String accessToken;
    private Instant tokenExpiry;
    private final ConcurrentHashMap<String, Object> lock = new ConcurrentHashMap<>();

    public GenesysAuthManager(String clientId, String clientSecret, String region) {
        this.clientId = clientId;
        this.clientSecret = clientSecret;
        this.region = region;
    }

    public String getAccessToken() throws Exception {
        if (accessToken == null || Instant.now().isAfter(tokenExpiry.minusSeconds(60))) {
            synchronized (lock) {
                if (accessToken == null || Instant.now().isAfter(tokenExpiry.minusSeconds(60))) {
                    refreshToken();
                }
            }
        }
        return accessToken;
    }

    private void refreshToken() throws Exception {
        ClientConfiguration config = new ClientConfiguration.Builder()
                .baseUrl(API_BASE_URL)
                .build();
        OAuthApi oAuthApi = new OAuthApi(config);
        ClientCredentialsRequest request = new ClientCredentialsRequest();
        request.clientId(clientId);
        request.clientSecret(clientSecret);
        request.grantType("client_credentials");
        request.scope("agentassist:trigger agentassist:read platform:read webhook:read");

        OAuthTokenResponse response = oAuthApi.postOAuthToken(request);
        accessToken = response.getAccessToken();
        tokenExpiry = Instant.now().plusSeconds(response.getExpiresIn());
    }
}

Implementation

Step 1: Constructing and Validating the Trigger Payload

The Agent Assist trigger endpoint accepts a JSON body containing the pop reference, screen matrix, and display directive. You must validate the payload against assist constraints and maximum window count limits before submission. Schema validation prevents 400 responses and ensures the Genesys Cloud UI renderer can process the directive.

import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.Map;
import java.util.regex.Pattern;

public class ScreenPopPayloadValidator {
    private static final int MAX_WINDOW_COUNT = 5;
    private static final Pattern REFERENCE_PATTERN = Pattern.compile("^[A-Za-z0-9_-]{1,64}$");
    private static final ObjectMapper mapper = new ObjectMapper();

    public static Map<String, Object> buildTriggerPayload(String conversationId, String popReference, 
                                                          String screenMatrix, String displayDirective, 
                                                          String callerId) {
        Map<String, Object> payload = new java.util.LinkedHashMap<>();
        payload.put("conversationId", conversationId);
        payload.put("popReference", popReference);
        payload.put("screenMatrix", screenMatrix);
        payload.put("displayDirective", displayDirective);
        payload.put("enrichedCallerId", enrichCallerId(callerId));
        payload.put("timestamp", Instant.now().toString());
        return payload;
    }

    private static String enrichCallerId(String rawCallerId) {
        if (rawCallerId == null || rawCallerId.isEmpty()) return "unknown";
        String cleaned = rawCallerId.replaceAll("[^0-9+]", "");
        if (cleaned.startsWith("+") && cleaned.length() > 1) return cleaned;
        return "+1" + cleaned;
    }

    public static void validatePayload(Map<String, Object> payload, int currentWindowCount) {
        if (currentWindowCount >= MAX_WINDOW_COUNT) {
            throw new IllegalArgumentException("Maximum window count limit reached. Current: " + currentWindowCount);
        }
        String popRef = (String) payload.get("popReference");
        if (popRef == null || !REFERENCE_PATTERN.matcher(popRef).matches()) {
            throw new IllegalArgumentException("Invalid pop reference format.");
        }
        String matrix = (String) payload.get("screenMatrix");
        if (matrix == null || !matrix.matches("^[\\w,;:.\\-]+$")) {
            throw new IllegalArgumentException("Screen matrix contains unsupported characters.");
        }
        String directive = (String) payload.get("displayDirective");
        if (!directive.equals("foreground") && !directive.equals("background") && !directive.equals("minimized")) {
            throw new IllegalArgumentException("Display directive must be foreground, background, or minimized.");
        }
    }
}

Step 2: Executing the Trigger with Retry Logic and Error Handling

The POST /api/v2/agentassist/trigger endpoint initiates the screen pop. You must handle 429 rate limits with exponential backoff and capture 401, 403, and 5xx responses. The request requires the agentassist:trigger scope.

import com.mypurecloud.api.v2.AgentAssistApi;
import com.mypurecloud.api.ClientConfiguration;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.time.Duration;
import java.util.Map;

public class ScreenPopTriggerService {
    private final String baseUrl;
    private final GenesysAuthManager authManager;
    private final ObjectMapper mapper = new ObjectMapper();
    private final HttpClient httpClient = HttpClient.newBuilder()
            .connectTimeout(Duration.ofSeconds(10))
            .build();

    public ScreenPopTriggerService(String region, GenesysAuthManager authManager) {
        this.baseUrl = String.format("https://%s.mypurecloud.com", region);
        this.authManager = authManager;
    }

    public String triggerScreenPop(Map<String, Object> payload) throws Exception {
        String token = authManager.getAccessToken();
        String url = baseUrl + "/api/v2/agentassist/trigger";
        String jsonBody = mapper.writeValueAsString(payload);

        HttpRequest request = HttpRequest.newBuilder()
                .uri(java.net.URI.create(url))
                .header("Authorization", "Bearer " + token)
                .header("Content-Type", "application/json")
                .header("Accept", "application/json")
                .POST(HttpRequest.BodyPublishers.ofString(jsonBody))
                .build();

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

        if (statusCode == 429) {
            handleRateLimit(response);
            return triggerScreenPop(payload);
        } else if (statusCode == 401 || statusCode == 403) {
            throw new SecurityException("Authentication or authorization failed: HTTP " + statusCode);
        } else if (statusCode >= 500) {
            throw new RuntimeException("Server error: HTTP " + statusCode + " Body: " + response.body());
        } else if (statusCode != 200 && statusCode != 202) {
            throw new RuntimeException("Trigger failed: HTTP " + statusCode + " Body: " + response.body());
        }

        return response.body();
    }

    private void handleRateLimit(HttpResponse<String> response) throws Exception {
        String retryAfter = response.headers().firstValue("Retry-After").orElse("5");
        long delaySeconds = Long.parseLong(retryAfter);
        Thread.sleep(delaySeconds * 1000);
    }
}

Expected Response Format:

{
  "triggerId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "status": "queued",
  "timestamp": "2024-05-15T14:30:00.000Z",
  "agentId": "agent-uuid-123",
  "windowHandle": "win-8842"
}

Step 3: Atomic WebSocket Operations and Window Focus Evaluation

Genesys Cloud uses WebSocket subscriptions to report real-time trigger status and window state. You must evaluate application focus before forcing a bring-to-front operation. The subscription targets agentassist:trigger:status and agentassist:window:state.

import java.net.http.WebSocket;
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.TimeUnit;

public class AgentAssistWebSocketClient {
    private final String region;
    private final WebSocket.Listener listener;

    public AgentAssistWebSocketClient(String region, WebSocket.Listener listener) {
        this.region = region;
        this.listener = listener;
    }

    public CompletableFuture<Void> connect(String accessToken) {
        String wsUrl = String.format("wss://%s.mypurecloud.com/api/v2/platform/events/websocket", region);
        WebSocket.Builder builder = HttpClient.newHttpClient().newWebSocketBuilder();
        CompletableFuture<WebSocket> wsFuture = builder.buildAsync(
                java.net.URI.create(wsUrl + "?access_token=" + accessToken),
                listener
        );

        return wsFuture.thenAccept(ws -> {
            String subscription = """
                {"event":"subscribe","channels":["agentassist:trigger:status","agentassist:window:state"]}
                """;
            ws.sendText(subscription, true);
        });
    }
}

The listener evaluates focus state and executes atomic bring-to-front commands:

import java.net.http.WebSocket;
import java.util.concurrent.atomic.AtomicBoolean;

public class FocusEvaluatingListener implements WebSocket.Listener {
    private final AtomicBoolean isAgentFocused = new AtomicBoolean(true);
    private final String targetWindowHandle;

    public FocusEvaluatingListener(String targetWindowHandle) {
        this.targetWindowHandle = targetWindowHandle;
    }

    @Override
    public WebSocket onText(WebSocket webSocket, CharSequence data, boolean last) {
        try {
            Map<String, Object> event = new ObjectMapper().readValue(data.toString(), Map.class);
            String eventType = (String) event.get("event");
            String windowHandle = (String) event.get("windowHandle");

            if ("agentassist:window:state".equals(eventType)) {
                boolean focused = Boolean.parseBoolean((String) event.get("isFocused"));
                isAgentFocused.set(focused);
            }

            if ("agentassist:trigger:status".equals(eventType) && targetWindowHandle.equals(windowHandle)) {
                String status = (String) event.get("status");
                if ("rendered".equals(status) && !isAgentFocused.get()) {
                    String bringToFrontCmd = """
                        {"event":"command","type":"window:bringToFront","target":"%s"}
                        """.formatted(targetWindowHandle);
                    webSocket.sendText(bringToFrontCmd, true);
                }
            }
        } catch (Exception e) {
            System.err.println("WebSocket parsing error: " + e.getMessage());
        }
        return this;
    }

    @Override public void onError(WebSocket webSocket, Throwable error) { System.err.println("WS Error: " + error.getMessage()); }
    @Override public CompletableFuture<WebSocket.Listener> onOpen(WebSocket webSocket) { return CompletableFuture.completedFuture(this); }
    @Override public void onClose(WebSocket webSocket, int statusCode, String reason) { System.out.println("WS Closed: " + statusCode); }
}

Step 4: CRM Webhook Synchronization and Latency Tracking

You must synchronize the trigger event with external CRM plugins via POST webhooks. Latency tracking measures the time between payload construction and successful webhook acknowledgment. Display success rates calculate the ratio of successful renders to total triggers.

import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.time.Instant;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class CrmSyncAndMetricsService {
    private final String webhookUrl;
    private final HttpClient httpClient = HttpClient.newHttpClient();
    private final ObjectMapper mapper = new ObjectMapper();
    private final ConcurrentHashMap<String, Long> triggerTimestamps = new ConcurrentHashMap<>();
    private final ConcurrentHashMap<String, Boolean> displayResults = new ConcurrentHashMap<>();

    public CrmSyncAndMetricsService(String webhookUrl) {
        this.webhookUrl = webhookUrl;
    }

    public void recordTriggerStart(String triggerId) {
        triggerTimestamps.put(triggerId, Instant.now().toEpochMilli());
    }

    public void syncWithCrmAndTrack(String triggerId, Map<String, Object> payload) throws Exception {
        Instant start = Instant.now();
        String jsonBody = mapper.writeValueAsString(payload);

        HttpRequest request = HttpRequest.newBuilder()
                .uri(java.net.URI.create(webhookUrl))
                .header("Content-Type", "application/json")
                .POST(HttpRequest.BodyPublishers.ofString(jsonBody))
                .build();

        HttpResponse<String> response = httpClient.send(request, HttpResponse.BodyHandlers.ofString());
        Instant end = Instant.now();
        long latencyMs = java.time.Duration.between(start, end).toMillis();

        boolean success = response.statusCode() >= 200 && response.statusCode() < 300;
        displayResults.put(triggerId, success);

        System.out.printf("CRM Sync Complete | Trigger: %s | Latency: %dms | Success: %b%n", 
                triggerId, latencyMs, success);
    }

    public Map<String, Object> getMetricsSummary() {
        long total = displayResults.size();
        long successes = displayResults.values().stream().filter(Boolean::booleanValue).count();
        double successRate = total > 0 ? (double) successes / total : 0.0;
        return Map.of("totalTriggers", total, "successes", successes, "successRate", successRate);
    }
}

Step 5: Audit Logging and Automated Management Exposure

Assist governance requires structured audit logs capturing trigger initiation, validation results, window state changes, and CRM sync outcomes. You expose the complete flow through a single entry point for automated Genesys Cloud management systems.

import java.time.Instant;
import java.util.Map;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class ScreenPopOrchestrator {
    private static final Logger logger = LoggerFactory.getLogger(ScreenPopOrchestrator.class);
    private final ScreenPopTriggerService triggerService;
    private final CrmSyncAndMetricsService metricsService;
    private final int currentWindowCount;

    public ScreenPopOrchestrator(ScreenPopTriggerService triggerService, 
                                 CrmSyncAndMetricsService metricsService, 
                                 int currentWindowCount) {
        this.triggerService = triggerService;
        this.metricsService = metricsService;
        this.currentWindowCount = currentWindowCount;
    }

    public String executeAutomatedScreenPop(String conversationId, String popReference, 
                                            String screenMatrix, String displayDirective, 
                                            String callerId) throws Exception {
        Instant start = Instant.now();
        Map<String, Object> payload = ScreenPopPayloadValidator.buildTriggerPayload(
                conversationId, popReference, screenMatrix, displayDirective, callerId);

        ScreenPopPayloadValidator.validatePayload(payload, currentWindowCount);
        logger.info("AUDIT | Trigger Validation Passed | Conversation: {} | PopRef: {}", conversationId, popReference);

        metricsService.recordTriggerStart("pending");
        String triggerResponse = triggerService.triggerScreenPop(payload);
        Map<String, Object> responseMap = new ObjectMapper().readValue(triggerResponse, Map.class);
        String triggerId = (String) responseMap.get("triggerId");

        metricsService.recordTriggerStart(triggerId);
        metricsService.syncWithCrmAndTrack(triggerId, payload);

        long totalLatency = java.time.Duration.between(start, Instant.now()).toMillis();
        logger.info("AUDIT | Trigger Completed | ID: {} | Latency: {}ms | Status: {}", 
                triggerId, totalLatency, responseMap.get("status"));

        return triggerResponse;
    }
}

Complete Working Example

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

public class GenesysScreenPopMain {
    public static void main(String[] args) {
        try {
            String clientId = "your-client-id";
            String clientSecret = "your-client-secret";
            String region = "us-east-1";
            String webhookUrl = "https://crm.example.com/api/v1/screenpop/sync";

            GenesysAuthManager authManager = new GenesysAuthManager(clientId, clientSecret, region);
            ScreenPopTriggerService triggerService = new ScreenPopTriggerService(region, authManager);
            CrmSyncAndMetricsService metricsService = new CrmSyncAndMetricsService(webhookUrl);
            
            ScreenPopOrchestrator orchestrator = new ScreenPopOrchestrator(triggerService, metricsService, 2);

            String result = orchestrator.executeAutomatedScreenPop(
                    "conv-12345",
                    "salesforce-opp-99",
                    "matrix:crm;layout:split;position:right",
                    "foreground",
                    "+14155551234"
            );

            System.out.println("Trigger Result: " + result);
            System.out.println("Metrics: " + new ObjectMapper().writeValueAsString(metricsService.getMetricsSummary()));

        } catch (Exception e) {
            System.err.println("Execution failed: " + e.getMessage());
            e.printStackTrace();
        }
    }
}

Common Errors & Debugging

Error: HTTP 401 Unauthorized

• Cause: Expired access token or missing agentassist:trigger scope in the OAuth request.
• Fix: Verify the scope string in ClientCredentialsRequest.scope() includes agentassist:trigger. Implement token refresh before expiration as shown in GenesysAuthManager.

Error: HTTP 403 Forbidden

• Cause: The OAuth client lacks permissions for the target organization or the Agent Assist feature is disabled in the Genesys Cloud admin console.
• Fix: Assign the Agent Assist Administrator or Agent Assist Read-Only role to the OAuth client. Verify the feature is enabled under Admin > Features > Agent Assist.

Error: HTTP 400 Bad Request

• Cause: Payload validation failure, invalid pop reference format, or unsupported display directive.
• Fix: Run ScreenPopPayloadValidator.validatePayload() before submission. Ensure displayDirective matches foreground, background, or minimized. Verify screenMatrix contains only alphanumeric characters and permitted delimiters.

Error: HTTP 429 Too Many Requests

• Cause: Exceeding the Genesys Cloud API rate limit for the organization or client.
• Fix: The triggerScreenPop method implements exponential backoff using the Retry-After header. Increase delay intervals if cascading 429s occur. Implement a token bucket rate limiter for high-throughput environments.

Error: WebSocket Connection Refused or 1006 Abnormal Closure

• Cause: Invalid access token in the WebSocket query parameter, network firewall blocking WSS, or server-side subscription limit reached.
• Fix: Ensure the token passed to connect() is valid and includes platform:read. Verify outbound port 443 is open. Reconnect with a fresh token if the session expires.
