Recording Genesys Cloud Voice Interactions via Media API with Java

What You Will Build

• This tutorial builds a production-grade Java service that initiates, validates, and tracks voice conversation recordings against the Genesys Cloud Media API.
• The code uses the PureCloudPlatformClientV2 Java SDK to execute atomic recording POST operations, enforce schema and duration constraints, and sync recording events to external archiving systems via webhook payloads.
• The implementation covers Java 17+ with the official Genesys Cloud Java SDK.

Prerequisites

• OAuth2 Client Credentials grant or JWT service account authentication
• Required OAuth scopes: conversation:read, conversation:write, recording:write, recording:read
• SDK version: genesyscloud-java-sdk v3.0.0 or later
• Runtime: Java 17+ (JDK 17 LTS recommended)
• External dependencies: com.fasterxml.jackson.core:jackson-databind (JSON serialization), org.slf4j:slf4j-api (logging), io.github.resilience4j:resilience4j-retry (optional for 429 handling)

Authentication Setup

Genesys Cloud requires OAuth2 bearer tokens for all API calls. The Java SDK handles token caching and automatic refresh when configured correctly. The following initialization establishes a secure, reusable client instance.

import com.genesiscloud.platform.client.v2.ApiClient;
import com.genesiscloud.platform.client.v2.auth.OAuth2;
import com.genesiscloud.platform.client.v2.auth.clientcredentials.ClientCredentials;
import com.genesiscloud.platform.client.v2.api.ConversationsApi;
import com.genesiscloud.platform.client.v2.api.RecordingsApi;
import java.util.concurrent.CompletableFuture;

public class GenesysAuth {
    private static final String REGION = System.getenv("GENESYS_REGION"); // e.g., "mypurecloud.com"
    private static final String CLIENT_ID = System.getenv("GENESYS_CLIENT_ID");
    private static final String CLIENT_SECRET = System.getenv("GENESYS_CLIENT_SECRET");
    private static final String SCOPES = "conversation:read conversation:write recording:read recording:write";

    public static ApiClient initializeClient() throws Exception {
        ApiClient client = new ApiClient(REGION);
        
        OAuth2 oauth2 = new OAuth2(client);
        ClientCredentials credentials = new ClientCredentials(CLIENT_ID, CLIENT_SECRET);
        credentials.setScopes(SCOPES.split(" "));
        
        // The SDK automatically caches and refreshes tokens
        oauth2.setClientCredentials(credentials);
        client.setAuth(oauth2);
        
        return client;
    }
}

The oauth2.setClientCredentials(credentials) call binds the token flow to the ApiClient. The SDK maintains an in-memory token cache and triggers a silent refresh before expiration. You must set the GENESYS_REGION, GENESYS_CLIENT_ID, and GENESYS_CLIENT_SECRET environment variables before execution.

Implementation

Step 1: Initialize Client and Validate Conversation State

Before initiating a recording, you must verify that the target conversation exists, is in a recordable state, and supports the requested media pipeline. The following code fetches conversation metadata and validates carrier capability.

import com.genesiscloud.platform.client.v2.api.ConversationsApi;
import com.genesiscloud.platform.client.v2.model.Conversation;
import com.genesiscloud.platform.client.v2.ApiException;
import java.util.Set;
import java.util.HashSet;

public class ConversationValidator {
    private static final Set<String> RECORDABLE_STATES = Set.of("connected", "monitoring", "whisper");
    private static final Set<String> SUPPORTED_TYPES = Set.of("voice", "video");

    public static boolean validateConversation(ConversationsApi conversationsApi, String conversationId) throws ApiException {
        // GET /api/v2/conversations/{conversationId}
        // Scopes: conversation:read
        Conversation conversation = conversationsApi.getConversation(conversationId, null, null);
        
        if (conversation == null) {
            throw new IllegalStateException("Conversation not found: " + conversationId);
        }
        
        if (!SUPPORTED_TYPES.contains(conversation.getType())) {
            throw new IllegalArgumentException("Unsupported conversation type for recording: " + conversation.getType());
        }
        
        if (!RECORDABLE_STATES.contains(conversation.getState())) {
            throw new IllegalStateException("Conversation is not in a recordable state: " + conversation.getState());
        }
        
        return true;
    }
}

The getConversation call returns the current state, type, and participant list. The validation rejects queued, ringing, or ended states to prevent wasted API calls and storage allocation failures.

Step 2: Construct and Validate Recording Payload

Genesys Cloud enforces strict media engine constraints. You must validate the codec matrix, storage path directive, and maximum duration before sending the payload. The media engine supports a specific set of codecs and enforces a default maximum duration of 600 minutes (10 hours).

import com.genesiscloud.platform.client.v2.model.CreateRecordingRequest;
import java.util.Set;

public class RecordingPayloadBuilder {
    private static final Set<String> SUPPORTED_CODECS = Set.of(
        "L16", "WAV", "MP3", "FLAC", "G729", "G711U", "G711A", "PCMA", "PCMU", "AAC", "OPUS"
    );
    private static final int MAX_DURATION_MINUTES = 600; // Genesys Cloud default limit
    private static final String STORAGE_PATH_TEMPLATE = "/recordings/voice/{conversationId}/{timestamp}.wav";

    public static CreateRecordingRequest buildAndValidatePayload(String conversationId, String requestedFormat, Integer requestedDurationMinutes, String storagePath) throws Exception {
        // Format verification against codec matrix
        String validatedFormat = (requestedFormat != null) ? requestedFormat.toUpperCase() : "L16";
        if (!SUPPORTED_CODECS.contains(validatedFormat)) {
            throw new IllegalArgumentException("Unsupported codec: " + validatedFormat + ". Must be one of: " + SUPPORTED_CODECS);
        }

        // Duration validation against media engine constraints
        int validatedDuration = (requestedDurationMinutes != null) ? requestedDurationMinutes : 0;
        if (validatedDuration > MAX_DURATION_MINUTES) {
            throw new IllegalArgumentException("Duration " + validatedDuration + " exceeds maximum limit of " + MAX_DURATION_MINUTES + " minutes.");
        }

        // Storage path directive validation
        String validatedStoragePath = (storagePath != null && !storagePath.isEmpty()) ? storagePath : STORAGE_PATH_TEMPLATE.replace("{conversationId}", conversationId);
        if (!validatedStoragePath.startsWith("/recordings/")) {
            throw new IllegalArgumentException("Storage path must begin with /recordings/");
        }

        CreateRecordingRequest request = new CreateRecordingRequest();
        request.setType("conversation");
        request.setFormat(validatedFormat);
        request.setStoragePath(validatedStoragePath);
        request.setDuration(validatedDuration);
        request.setRecordedParticipants("all");
        
        return request;
    }
}

The CreateRecordingRequest object maps directly to the JSON payload sent to the Media API. The storagePath directive uses Genesys Cloud template variables. The codec validation prevents the media engine from rejecting the request with a 400 Bad Request.

Step 3: Execute Atomic POST and Handle Stream Capture

The recording initiation is an atomic POST operation. The API returns a 201 Created response with the recording ID and metadata. You must handle 429 rate limits and 5xx transient failures with retry logic.

import com.genesiscloud.platform.client.v2.api.ConversationsApi;
import com.genesiscloud.platform.client.v2.model.CreateRecordingRequest;
import com.genesiscloud.platform.client.v2.model.Recording;
import com.genesiscloud.platform.client.v2.ApiException;
import java.time.Instant;
import java.util.logging.Logger;

public class RecordingInitiator {
    private static final Logger logger = Logger.getLogger(RecordingInitiator.class.getName());
    private static final int MAX_RETRIES = 3;

    public static Recording initiateRecording(ConversationsApi conversationsApi, String conversationId, CreateRecordingRequest request) throws Exception {
        // POST /api/v2/conversations/{conversationId}/recordings
        // Scopes: conversation:write, recording:write
        Recording response = null;
        Exception lastException = null;

        for (int attempt = 1; attempt <= MAX_RETRIES; attempt++) {
            try {
                response = conversationsApi.postConversationRecordings(conversationId, request);
                logger.info("Recording initiated successfully: " + response.getId());
                return response;
            } catch (ApiException e) {
                lastException = e;
                if (e.getCode() == 429 || e.getCode() >= 500) {
                    long waitTime = Math.pow(2, attempt) * 1000; // Exponential backoff
                    logger.warning("Transient error " + e.getCode() + ". Retrying in " + waitTime + "ms...");
                    Thread.sleep(waitTime);
                } else {
                    // Non-retryable errors: 400, 401, 403, 404, 409, 412
                    throw new RuntimeException("Recording initiation failed with status " + e.getCode() + ": " + e.getMessage(), e);
                }
            }
        }
        throw new RuntimeException("Failed to initiate recording after " + MAX_RETRIES + " attempts", lastException);
    }
}

The postConversationRecordings method triggers the automatic stream capture pipeline. Genesys Cloud routes the audio stream to the media engine, applies the codec, and writes to the storage path. The response contains the recordingId, state, and url for the media file once processing completes.

Step 4: Webhook Synchronization and Audit Logging

Recording events must synchronize with external archiving gateways. Genesys Cloud sends webhook callbacks when recording state changes. You must parse the payload, calculate latency, verify audio integrity scores, and generate audit logs.

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

public class RecordingEventProcessor {
    private static final ObjectMapper mapper = new ObjectMapper();

    public static void processWebhookPayload(String payloadJson) throws Exception {
        Map<String, Object> event = mapper.readValue(payloadJson, Map.class);
        String recordingId = (String) event.get("id");
        String state = (String) event.get("state");
        String conversationId = (String) event.get("conversationId");
        Long createdTimestamp = (Long) event.get("createdTimestamp");
        Long updatedTimestamp = (Long) event.get("updatedTimestamp");

        if (!"completed".equals(state)) {
            return; // Only process completed recordings for archiving
        }

        // Calculate latency
        long latencyMs = updatedTimestamp - createdTimestamp;
        double audioIntegrityScore = calculateIntegrityScore(latencyMs, state);

        // Generate audit log
        Map<String, Object> auditLog = Map.of(
            "timestamp", Instant.now().toString(),
            "recordingId", recordingId,
            "conversationId", conversationId,
            "state", state,
            "latencyMs", latencyMs,
            "audioIntegrityScore", audioIntegrityScore,
            "governanceTag", "compliance-archive"
        );

        String auditJson = mapper.writeValueAsString(auditLog);
        System.out.println("AUDIT_LOG: " + auditJson);

        // Trigger external archiving gateway synchronization
        syncToArchivingGateway(recordingId, auditJson);
    }

    private static double calculateIntegrityScore(long latencyMs, String state) {
        // Simulated integrity scoring based on latency and state completion
        if (!"completed".equals(state)) return 0.0;
        double score = 100.0;
        if (latencyMs > 300000) score -= 20.0; // Penalty for high latency
        if (latencyMs > 600000) score -= 30.0;
        return Math.max(0.0, score);
    }

    private static void syncToArchivingGateway(String recordingId, String auditJson) {
        // In production, this would be an HTTP POST to your archiving system
        System.out.println("SYNC_TRIGGER: Recording " + recordingId + " queued for external gateway. Audit: " + auditJson);
    }
}

The webhook processor validates the state field, calculates processing latency, assigns an integrity score, and emits a structured audit log. The syncToArchivingGateway method serves as the integration point for your external storage or compliance system.

import com.genesiscloud.platform.client.v2.api.ConversationsApi;
import com.genesiscloud.platform.client.v2.model.CreateRecordingRequest;
import com.genesiscloud.platform.client.v2.model.Recording;

import java.util.logging.Logger;

public class AutomatedCallRecorder {
    private static final Logger logger = Logger.getLogger(AutomatedCallRecorder.class.getName());
    private final ConversationsApi conversationsApi;
    private final ConversationValidator validator;
    private final RecordingPayloadBuilder payloadBuilder;
    private final RecordingInitiator initiator;

    public AutomatedCallRecorder(ApiClient client) {
        this.conversationsApi = new ConversationsApi(client);
        this.validator = new ConversationValidator();
        this.payloadBuilder = new RecordingPayloadBuilder();
        this.initiator = new RecordingInitiator();
    }

    public Recording startRecording(String conversationId, String format, Integer durationMinutes, String storagePath) throws Exception {
        logger.info("Validating conversation: " + conversationId);
        validator.validateConversation(conversationsApi, conversationId);

        logger.info("Building recording payload for conversation: " + conversationId);
        CreateRecordingRequest request = payloadBuilder.buildAndValidatePayload(
            conversationId, format, durationMinutes, storagePath
        );

        logger.info("Initiating atomic recording POST for conversation: " + conversationId);
        Recording recording = initiator.initiateRecording(conversationsApi, conversationId, request);

        logger.info("Recording initiated. ID: " + recording.getId() + ", State: " + recording.getState());
        return recording;
    }

    public static void main(String[] args) {
        try {
            ApiClient client = GenesysAuth.initializeClient();
            AutomatedCallRecorder recorder = new AutomatedCallRecorder(client);

            // Example invocation
            String targetConversationId = System.getenv("TARGET_CONVERSATION_ID");
            if (targetConversationId == null) {
                throw new IllegalArgumentException("TARGET_CONVERSATION_ID environment variable is required");
            }

            Recording result = recorder.startRecording(
                targetConversationId,
                "L16",
                120,
                "/recordings/voice/" + targetConversationId + "/capture.wav"
            );

            System.out.println("SUCCESS: Recording started. ID=" + result.getId() + " URL=" + result.getUrl());
        } catch (Exception e) {
            logger.severe("Recording workflow failed: " + e.getMessage());
            e.printStackTrace();
        }
    }
}

This module handles authentication, validation, payload construction, atomic initiation, and error recovery. You only need to set the environment variables and provide a valid conversationId to execute the workflow.

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: OAuth token expired, invalid credentials, or missing conversation:write scope.
• Fix: Verify environment variables. Ensure the OAuth client has the conversation:write and recording:write scopes assigned in the Genesys Cloud admin console. The SDK refreshes tokens automatically, but initial authorization requires correct scope assignment.
• Code Fix: Add explicit scope logging during initialization.

Error: 403 Forbidden

• Cause: The OAuth client lacks permission to record conversations, or the organization has disabled recording for specific user groups.
• Fix: Check the OAuth client permissions in Genesys Cloud. Verify that the user or service account has the Recording capability enabled in their security profile.
• Code Fix: Catch ApiException with code 403 and log the client ID for audit review.

Error: 409 Conflict

• Cause: A recording is already active for the conversation, or the conversation state prevents recording.
• Fix: Call GET /api/v2/conversations/{conversationId}/recordings to check existing recordings. Wait for the conversation to enter a connected state before retrying.
• Code Fix: Implement a pre-flight check that queries active recordings before POSTing.

Error: 429 Too Many Requests

• Cause: Rate limit exceeded on the Media API or Conversation API.
• Fix: The RecordingInitiator class implements exponential backoff. If failures persist, reduce request frequency or implement a queue-based scheduler.
• Code Fix: Monitor the Retry-After header in the response. Adjust MAX_RETRIES and backoff multipliers based on your throughput requirements.

Error: 500 Internal Server Error

• Cause: Media engine scaling event, storage backend failure, or transient platform outage.
• Fix: Retry with exponential backoff. If the error persists beyond 5 minutes, check Genesys Cloud status page. Do not retry indefinitely.
• Code Fix: Add a circuit breaker pattern around the initiateRecording method to prevent cascading failures.
