Adding Genesys Cloud Agent Assist Keywords via REST API with Java

What You Will Build

A Java utility that programmatically creates Agent Assist keywords with synonym matrices, case sensitivity directives, and priority weights, validates against engine constraints, tracks creation latency, generates structured audit logs, and triggers external knowledge base synchronization. This tutorial uses the Genesys Cloud Java SDK and direct REST endpoints. The code is written in Java 17 and requires no external UI interactions.

Prerequisites

• OAuth client type: Confidential Client (Client Credentials flow)
• Required OAuth scopes: agentassist:keyword:create, agentassist:keyword:view
• SDK version: genesyscloud-java-sdk v2.12.0 or higher
• Runtime: Java 17 LTS or higher
• External dependencies: com.fasterxml.jackson.core:jackson-databind:2.15.2, org.slf4j:slf4j-simple:2.0.9
• Maven dependency for SDK:

<dependency>
    <groupId>com.genesiscloud</groupId>
    <artifactId>genesyscloud-java-sdk</artifactId>
    <version>2.12.0</version>
</dependency>

Authentication Setup

Genesys Cloud requires OAuth 2.0 for all API access. The Java SDK provides OAuthApiClient to handle token acquisition. You must cache the access token and handle expiration to avoid repeated network calls. The following code demonstrates the client credentials flow with basic token caching.

import com.genesiscloud.client.ApiClient;
import com.genesiscloud.client.auth.OAuthApiClient;
import com.genesiscloud.client.auth.model.OAuthClientCredentialsRequest;
import com.genesiscloud.client.auth.model.OAuthTokenResponse;
import java.util.concurrent.ConcurrentHashMap;

public class AuthManager {
    private static final String BASE_PATH = "https://api.mypurecloud.com";
    private static final String CLIENT_ID = "YOUR_CLIENT_ID";
    private static final String CLIENT_SECRET = "YOUR_CLIENT_SECRET";
    private static final ConcurrentHashMap<String, String> tokenCache = new ConcurrentHashMap<>();

    public static ApiClient getAuthenticatedApiClient() throws Exception {
        ApiClient apiClient = new ApiClient();
        apiClient.setBasePath(BASE_PATH);

        // Check cache first
        String cachedToken = tokenCache.get("genesys_access_token");
        if (cachedToken != null) {
            apiClient.setAccessToken(cachedToken);
            return apiClient;
        }

        OAuthApiClient oauthApiClient = new OAuthApiClient(apiClient);
        OAuthClientCredentialsRequest credentials = new OAuthClientCredentialsRequest()
            .clientSecret(CLIENT_SECRET)
            .clientId(CLIENT_ID)
            .scope("agentassist:keyword:create agentassist:keyword:view");

        try {
            OAuthTokenResponse response = oauthApiClient.postOAuthTokenClientCredentials(credentials).getResponse();
            String token = response.getAccessToken();
            tokenCache.put("genesys_access_token", token);
            apiClient.setAccessToken(token);
            return apiClient;
        } catch (Exception e) {
            throw new RuntimeException("OAuth token acquisition failed: " + e.getMessage(), e);
        }
    }
}

The scope parameter explicitly requests agentassist:keyword:create and agentassist:keyword:view. Without these scopes, the SDK will return HTTP 403 Forbidden responses on subsequent calls. The cache prevents unnecessary token refreshes during batch operations.

Implementation

Step 1: Validation Pipeline and Constraint Enforcement

Before sending keywords to Genesys Cloud, you must validate the payload against engine constraints. The Agent Assist engine enforces maximum keyword counts per set, rejects duplicate entries, and restricts certain special characters that break regex matching. This step fetches existing keywords, checks for duplicates, validates character sets, and enforces a hard limit of 500 keywords per batch to prevent payload size errors.

import com.genesiscloud.client.api.AgentAssistApi;
import com.genesiscloud.client.model.Keyword;
import java.util.*;
import java.util.regex.Pattern;

public class KeywordValidator {
    private static final int MAX_BATCH_SIZE = 500;
    private static final Pattern ALLOWED_CHARS = Pattern.compile("^[a-zA-Z0-9\\s\\-_.]+$");
    private static final Set<String> existingKeywords = new HashSet<>();

    public static void validateAndLoadExisting(AgentAssistApi api) throws Exception {
        // Fetch existing keywords to prevent duplicates
        // GET /api/v2/agentassist/keywords
        var response = api.getAgentassistKeywords(null, null, null, null, null, null);
        List<Keyword> keywords = response.getEntities();
        for (Keyword k : keywords) {
            existingKeywords.add(k.getKeyword().toLowerCase());
        }
    }

    public static List<Keyword> validateKeywords(List<Keyword> requests) throws Exception {
        if (requests.size() > MAX_BATCH_SIZE) {
            throw new IllegalArgumentException("Batch size exceeds maximum limit of " + MAX_BATCH_SIZE);
        }

        List<Keyword> validKeywords = new ArrayList<>();
        Set<String> batchSeen = new HashSet<>();

        for (Keyword request : requests) {
            String keywordValue = request.getKeyword();
            if (keywordValue == null || keywordValue.trim().isEmpty()) {
                continue;
            }

            String normalized = keywordValue.toLowerCase();
            
            // Duplicate check within batch
            if (batchSeen.contains(normalized)) {
                continue;
            }
            
            // Duplicate check against existing Genesys data
            if (existingKeywords.contains(normalized)) {
                continue;
            }

            // Special character verification
            if (!ALLOWED_CHARS.matcher(keywordValue).matches()) {
                continue;
            }

            // Enforce case sensitivity and synonym matrix structure
            if (request.getCaseSensitive() == null) {
                request.setCaseSensitive(false);
            }
            if (request.getSynonyms() == null) {
                request.setSynonyms(new ArrayList<>());
            }
            if (request.getPriority() == null) {
                request.setPriority(1);
            }

            batchSeen.add(normalized);
            validKeywords.add(request);
        }

        return validKeywords;
    }
}

The validation pipeline operates in two phases. The first phase calls GET /api/v2/agentassist/keywords to populate a local set of existing keywords. The second phase iterates through the incoming batch, normalizes strings, checks against both the existing set and the current batch, and verifies character compliance. This prevents HTTP 409 Conflict responses and ensures the Assist engine receives clean data.

Step 2: Atomic POST Construction and Index Trigger Handling

Genesys Cloud processes keyword creation asynchronously. The API returns HTTP 201 Created immediately, but the search index rebuilds in the background. You must handle rate limiting, verify the response payload, and track latency. The following code constructs the atomic POST operation, implements exponential backoff for HTTP 429 responses, and captures timing metrics.

import com.genesiscloud.client.ApiException;
import com.genesiscloud.client.api.AgentAssistApi;
import com.genesiscloud.client.model.Keyword;
import java.time.Duration;
import java.time.Instant;
import java.util.List;

public class KeywordIngester {
    
    public static List<Keyword> ingestKeywords(AgentAssistApi api, List<Keyword> validatedKeywords) throws Exception {
        List<Keyword> createdKeywords = new ArrayList<>();
        int retryCount = 0;
        int maxRetries = 3;

        for (Keyword keywordRequest : validatedKeywords) {
            Instant start = Instant.now();
            
            while (retryCount <= maxRetries) {
                try {
                    // POST /api/v2/agentassist/keywords
                    // Request body example:
                    // {
                    //   "keyword": "billing dispute",
                    //   "synonyms": ["bill complaint", "payment issue"],
                    //   "caseSensitive": false,
                    //   "priority": 5
                    // }
                    Keyword response = api.postAgentassistKeywords(keywordRequest).getResponse();
                    
                    createdKeywords.add(response);
                    
                    Instant end = Instant.now();
                    Duration latency = Duration.between(start, end);
                    System.out.println(String.format("[AUDIT] Created keyword: %s | Latency: %d ms | ID: %s", 
                        response.getKeyword(), latency.toMillis(), response.getId()));
                    
                    // Genesys triggers automatic index rebuild on successful POST.
                    // No manual trigger is required. The response ID confirms acceptance.
                    break;
                } catch (ApiException e) {
                    if (e.getCode() == 429) {
                        long waitTime = (long) Math.pow(2, retryCount) * 1000;
                        System.out.println(String.format("[RATE_LIMIT] 429 received. Retrying in %d ms...", waitTime));
                        Thread.sleep(waitTime);
                        retryCount++;
                    } else {
                        throw e;
                    }
                } finally {
                    retryCount = 0;
                }
            }
        }
        return createdKeywords;
    }
}

The postAgentassistKeywords method sends a single atomic request per keyword. Genesys Cloud does not support bulk keyword creation in a single payload, so iteration is required. The code implements exponential backoff for HTTP 429 Too Many Requests responses. The latency tracker measures wall-clock time between request submission and response receipt. The automatic index rebuild is handled server-side; the API returns the newly assigned id field immediately, which confirms the keyword is queued for indexing.

Step 3: External Synchronization and Audit Logging

After successful keyword registration, you must synchronize the event with external knowledge base systems and generate governance audit logs. This step uses java.net.http.HttpClient to dispatch a webhook callback and writes structured JSON audit entries to a local file.

import com.genesiscloud.client.model.Keyword;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.FileWriter;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.nio.charset.StandardCharsets;
import java.time.Instant;
import java.util.List;
import java.util.Map;

public class SyncAndAuditManager {
    private static final String WEBHOOK_URL = "https://your-kb-sync-endpoint.com/api/v1/genesys/keywords";
    private static final String AUDIT_LOG_PATH = "agentassist_audit.log";
    private static final ObjectMapper mapper = new ObjectMapper();

    public static void syncAndAudit(List<Keyword> createdKeywords) throws Exception {
        for (Keyword keyword : createdKeywords) {
            // 1. External Webhook Synchronization
            syncExternalWebhook(keyword);
            
            // 2. Audit Log Generation
            writeAuditLog(keyword);
        }
    }

    private static void syncExternalWebhook(Keyword keyword) throws Exception {
        Map<String, Object> payload = Map.of(
            "event_type", "keyword_created",
            "genesys_id", keyword.getId(),
            "keyword", keyword.getKeyword(),
            "synonyms", keyword.getSynonyms(),
            "case_sensitive", keyword.getCaseSensitive(),
            "priority", keyword.getPriority(),
            "timestamp", Instant.now().toString()
        );

        String jsonPayload = mapper.writeValueAsString(payload);
        HttpRequest request = HttpRequest.newBuilder()
            .uri(URI.create(WEBHOOK_URL))
            .header("Content-Type", "application/json")
            .header("Authorization", "Bearer YOUR_WEBHOOK_SECRET")
            .POST(HttpRequest.BodyPublishers.ofString(jsonPayload, StandardCharsets.UTF_8))
            .build();

        HttpClient client = HttpClient.newHttpClient();
        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
        
        if (response.statusCode() != 200 && response.statusCode() != 201 && response.statusCode() != 202) {
            System.err.println(String.format("[SYNC_ERROR] Webhook failed with status %d: %s", response.statusCode(), response.body()));
        }
    }

    private static void writeAuditLog(Keyword keyword) throws Exception {
        Map<String, Object> auditEntry = Map.of(
            "action", "ADD_KEYWORD",
            "keyword_id", keyword.getId(),
            "keyword_value", keyword.getKeyword(),
            "synonyms_count", keyword.getSynonyms() != null ? keyword.getSynonyms().size() : 0,
            "case_sensitive", keyword.getCaseSensitive(),
            "created_at", Instant.now().toString(),
            "status", "SUCCESS"
        );

        String jsonLog = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(auditEntry);
        try (FileWriter writer = new FileWriter(AUDIT_LOG_PATH, true)) {
            writer.write(jsonLog + System.lineSeparator());
        }
    }
}

The synchronization routine serializes the created keyword into a structured JSON payload and POSTs it to an external endpoint. The audit logger writes a timestamped entry to a flat file for compliance tracking. Both operations run sequentially after successful API confirmation to ensure data consistency. The webhook callback aligns external knowledge bases with Genesys Assist configurations without manual intervention.

Complete Working Example

The following script combines authentication, validation, ingestion, synchronization, and audit logging into a single executable module. Replace the credential placeholders before running.

import com.genesiscloud.client.ApiClient;
import com.genesiscloud.client.api.AgentAssistApi;
import com.genesiscloud.client.model.Keyword;
import java.util.ArrayList;
import java.util.List;

public class AgentAssistKeywordAdder {
    public static void main(String[] args) {
        try {
            // 1. Authentication
            ApiClient apiClient = AuthManager.getAuthenticatedApiClient();
            AgentAssistApi agentAssistApi = new AgentAssistApi(apiClient);

            // 2. Validation Pipeline
            KeywordValidator.validateAndLoadExisting(agentAssistApi);
            
            // 3. Construct Payloads
            List<Keyword> keywordRequests = new ArrayList<>();
            
            Keyword kw1 = new Keyword();
            kw1.setKeyword("refund request");
            kw1.setSynonyms(List.of("money back", "return payment", "reimbursement"));
            kw1.setCaseSensitive(false);
            kw1.setPriority(10);
            keywordRequests.add(kw1);

            Keyword kw2 = new Keyword();
            kw2.setKeyword("account lockout");
            kw2.setSynonyms(List.of("locked out", "cannot login", "access denied"));
            kw2.setCaseSensitive(true);
            kw2.setPriority(8);
            keywordRequests.add(kw2);

            List<Keyword> validated = KeywordValidator.validateKeywords(keywordRequests);
            if (validated.isEmpty()) {
                System.out.println("No valid keywords to process after validation.");
                return;
            }

            // 4. Atomic POST and Index Handling
            List<Keyword> created = KeywordIngester.ingestKeywords(agentAssistApi, validated);

            // 5. External Sync and Audit
            SyncAndAuditManager.syncAndAudit(created);

            System.out.println(String.format("Successfully processed %d keywords.", created.size()));
        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        }
    }
}

Run the script with java AgentAssistKeywordAdder.java or compile via Maven. The module handles the full lifecycle from token acquisition to external synchronization. It requires only valid OAuth credentials and network access to the Genesys Cloud API domain.

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: Expired access token or missing OAuth scopes.
• Fix: Clear the token cache in AuthManager and re-execute the credentials flow. Verify the client application has agentassist:keyword:create assigned in the Genesys Cloud admin console.
• Code Fix: The AuthManager already caches tokens. Add a TTL check if running long-duration processes.

Error: 403 Forbidden

• Cause: The OAuth client lacks the required scope or the organization does not have Agent Assist enabled.
• Fix: Navigate to the Genesys Cloud admin console, locate the OAuth client, and add the agentassist:keyword:create scope. Confirm the product license includes Agent Assist.

Error: 409 Conflict

• Cause: Duplicate keyword submission. Genesys Cloud enforces unique keyword values per workspace.
• Fix: The KeywordValidator class handles this by fetching existing keywords and filtering duplicates before submission. Ensure the validateAndLoadExisting method runs before each batch.

Error: 429 Too Many Requests

• Cause: Exceeding the API rate limit (typically 500 requests per minute per client).
• Fix: The KeywordIngester implements exponential backoff. For high-volume operations, introduce a fixed delay between requests or distribute load across multiple OAuth clients.

Error: 400 Bad Request

• Cause: Invalid payload structure, unsupported special characters, or missing required fields.
• Fix: The ALLOWED_CHARS regex in KeywordValidator prevents invalid characters. Ensure keyword, synonyms, caseSensitive, and priority are populated. The SDK validates schema compliance before serialization.
