Restoring Soft-Deleted Genesys Cloud Users via Java SDK

What You Will Build

• A Java service that safely restores soft-deleted Genesys Cloud users by validating recovery windows, recalculating licenses, and updating group memberships.
• The implementation uses the official Genesys Cloud Java SDK (PureCloudPlatformClientV2) alongside direct HTTP fallback patterns and atomic PUT operations.
• The tutorial covers Java 17+ with production-grade error handling, retry logic, webhook synchronization, and structured audit logging.

Prerequisites

• OAuth Client Credentials grant type with scopes: user:read, user:write, license:write, group:read
• Genesys Cloud Java SDK v2.x (com.mypurecloud.api.client)
• Java 17 or higher
• External dependencies: com.google.code.gson:gson:2.10.1 for audit serialization, java.net.http (built-in)

Authentication Setup

The Genesys Cloud Java SDK handles token acquisition and automatic refresh when configured with client credentials. You must initialize the platform client before invoking any API.

import com.mypurecloud.api.client.PureCloudPlatformClientV2;
import com.mypurecloud.api.client.auth.OAuth2ClientCredentialsProvider;
import com.mypurecloud.api.client.ApiClient;

public class GenesysAuth {
    public static PureCloudPlatformClientV2 initializeClient(String environment, String clientId, String clientSecret) {
        PureCloudPlatformClientV2 client = new PureCloudPlatformClientV2();
        client.setEnvironment(environment);
        client.setAuthMethod(new OAuth2ClientCredentialsProvider(clientId, clientSecret));
        return client;
    }
}

Token caching is managed internally by the OAuth2ClientCredentialsProvider. The SDK automatically requests a new access token when the current one expires, preventing 401 Unauthorized errors during long-running restore batches.

Implementation

Step 1: Validate Identity Constraints and Recovery Window

Before attempting restoration, you must verify the user state, check the deprovision reason against security policies, and ensure the deletion timestamp falls within the maximum recovery window. Genesys Cloud retains soft-deleted users for a configurable period (typically 30 to 90 days). Attempting to restore outside this window returns a 422 Unprocessable Entity.

import com.mypurecloud.api.client.ApiException;
import com.mypurecloud.api.client.PureCloudPlatformClientV2;
import com.mypurecloud.api.domain.user.User;
import com.mypurecloud.api.client.ApiClient;
import com.mypurecloud.api.client.users.UsersApi;

import java.time.Instant;
import java.time.temporal.ChronoUnit;
import java.util.Set;

public class UserValidator {
    private static final Set<String> DENIED_DEPROVISION_REASONS = Set.of("SECURITY_BREACH", "TERMINATION_FRAUD");
    private static final long MAX_RECOVERY_DAYS = 45;

    public void validateRestoreEligibility(PureCloudPlatformClientV2 client, String userId) throws ApiException {
        UsersApi usersApi = new UsersApi(client);
        User user = usersApi.getUser(userId, null, null, null, null);

        if (!"deleted".equals(user.getStatus())) {
            throw new IllegalArgumentException("User is not in soft-deleted state. Current status: " + user.getStatus());
        }

        if (user.getDeletionDate() != null) {
            long daysSinceDeletion = ChronoUnit.DAYS.between(user.getDeletionDate().toInstant(), Instant.now());
            if (daysSinceDeletion > MAX_RECOVERY_DAYS) {
                throw new IllegalStateException("User exceeds maximum recovery window of " + MAX_RECOVERY_DAYS + " days.");
            }
        }

        if (user.getDeprovisionReason() != null && DENIED_DEPROVISION_REASONS.contains(user.getDeprovisionReason())) {
            throw new SecurityException("Restore blocked by security policy. Deprovision reason: " + user.getDeprovisionReason());
        }
    }
}

Expected Response: No response body. The method throws descriptive exceptions on validation failure.
Error Handling: ApiException with status 404 indicates the user ID does not exist or was permanently purged. Status 403 indicates missing user:read scope.

Step 2: Execute Atomic Restore and Profile Rebuild

The restore operation uses POST /api/v2/users/{userId}/restore. After restoration, you must execute an atomic PUT to verify profile format, enforce naming conventions, and trigger automatic profile rebuild routines. The SDK method postUserRestore handles the payload construction.

Raw HTTP Cycle Equivalent:

POST /api/v2/users/{userId}/restore HTTP/1.1
Host: api.us.genesyscloud.com
Authorization: Bearer <access_token>
Content-Type: application/json

{
  "userId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "restoreDate": "2024-01-15T10:30:00.000Z"
}

HTTP/1.1 200 OK
Content-Type: application/json
{
  "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "status": "active",
  "email": "agent@example.com",
  "name": "John Doe",
  "division": { "id": "default", "name": "Default" }
}

SDK Implementation with 429 Retry Logic:

import com.mypurecloud.api.client.ApiException;
import com.mypurecloud.api.client.PureCloudPlatformClientV2;
import com.mypurecloud.api.client.users.UsersApi;
import com.mypurecloud.api.domain.user.RestoreUserRequest;
import com.mypurecloud.api.domain.user.User;
import com.mypurecloud.api.domain.user.UserUpdate;

import java.time.Instant;
import java.util.concurrent.ThreadLocalRandom;

public class UserActivator {
    private final UsersApi usersApi;

    public UserActivator(PureCloudPlatformClientV2 client) {
        this.usersApi = new UsersApi(client);
    }

    public User restoreAndRebuildProfile(String userId) throws ApiException, InterruptedException {
        RestoreUserRequest restoreRequest = new RestoreUserRequest()
                .userId(userId)
                .restoreDate(Instant.now());

        User restoredUser = executeWithRetry(() -> usersApi.postUserRestore(userId, restoreRequest));

        // Atomic PUT for format verification and profile rebuild trigger
        UserUpdate profileUpdate = new UserUpdate()
                .name(restoredUser.getName()) // Enforce format verification
                .email(restoredUser.getEmail());
        
        return usersApi.putUser(userId, profileUpdate);
    }

    private User executeWithRetry(RunnableWithReturn<User> apiCall) throws ApiException, InterruptedException {
        int maxRetries = 3;
        for (int attempt = 1; attempt <= maxRetries; attempt++) {
            try {
                return apiCall.run();
            } catch (ApiException e) {
                if (e.getCode() == 429 && attempt < maxRetries) {
                    long backoffMs = (long) Math.pow(2, attempt) * 1000 + ThreadLocalRandom.current().nextInt(0, 1000);
                    Thread.sleep(backoffMs);
                } else {
                    throw e;
                }
            }
        }
        throw new ApiException("Max retries exceeded for restore operation.");
    }

    @FunctionalInterface
    interface RunnableWithReturn<T> {
        T run() throws ApiException;
    }
}

OAuth Scope Required: user:write
Error Handling: The retry loop catches 429 Too Many Requests and applies exponential backoff with jitter. 400 Bad Request indicates malformed profile fields. 409 Conflict indicates a concurrent update.

Step 3: License Reassignment and Group Membership Evaluation

After restoration, the user loses active license assignments and group memberships. You must recalculate licenses based on the user matrix and assign groups atomically using PUT /api/v2/users/{userId}/licenses and PUT /api/v2/users/{userId}/groups.

import com.mypurecloud.api.client.ApiException;
import com.mypurecloud.api.client.PureCloudPlatformClientV2;
import com.mypurecloud.api.client.users.UsersApi;
import com.mypurecloud.api.domain.user.LicenseAssignment;
import com.mypurecloud.api.domain.user.LicenseAssignmentUpdate;
import com.mypurecloud.api.domain.user.GroupMembership;
import com.mypurecloud.api.domain.user.GroupMembershipUpdate;

import java.time.Instant;
import java.util.List;

public class LicenseAndGroupManager {
    private final UsersApi usersApi;

    public LicenseAndGroupManager(PureCloudPlatformClientV2 client) {
        this.usersApi = new UsersApi(client);
    }

    public void assignLicensesAndGroups(String userId, List<String> licenseCodes, List<String> groupIds) throws ApiException {
        // License reassignment calculation
        List<LicenseAssignment> licenses = licenseCodes.stream()
                .map(code -> new LicenseAssignment()
                        .licenseCode(code)
                        .assignmentDate(Instant.now()))
                .toList();

        LicenseAssignmentUpdate licenseUpdate = new LicenseAssignmentUpdate().licenses(licenses);
        usersApi.putUserLicenses(userId, licenseUpdate);

        // Group membership evaluation logic
        List<GroupMembership> memberships = groupIds.stream()
                .map(groupId -> new GroupMembership().groupId(groupId))
                .toList();

        GroupMembershipUpdate groupUpdate = new GroupMembershipUpdate().groups(memberships);
        usersApi.putUserGroups(userId, groupUpdate);
    }
}

Expected Response: 204 No Content for both PUT operations.
Error Handling: 400 Bad Request occurs if a license code is invalid or already assigned. 404 Not Found indicates an invalid group ID. Always verify group existence via GET /api/v2/groups/{groupId} before assignment in production environments.

Step 4: HR Webhook Synchronization and Audit Metrics

You must synchronize the activation event with external HR systems and track latency, success rates, and audit trails. The following method uses java.net.http.HttpClient for webhook delivery and generates structured JSON audit logs.

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

import java.io.IOException;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.time.LocalDateTime;
import java.util.Map;
import java.util.concurrent.TimeUnit;

public class ActivationSyncLogger {
    private final HttpClient httpClient;
    private final Gson gson;
    private int successCount = 0;
    private int failureCount = 0;

    public ActivationSyncLogger(String webhookUrl) {
        this.httpClient = HttpClient.newBuilder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .build();
        this.gson = new GsonBuilder().setPrettyPrinting().create();
    }

    public void syncAndAudit(String userId, long latencyMs, boolean success, Map<String, Object> metadata) throws IOException, InterruptedException {
        if (success) {
            successCount++;
            triggerHrWebhook(userId, metadata);
        } else {
            failureCount++;
        }

        Map<String, Object> auditLog = Map.of(
                "timestamp", LocalDateTime.now().toString(),
                "userId", userId,
                "action", "USER_RESTORE",
                "latencyMs", latencyMs,
                "success", success,
                "successRate", calculateSuccessRate(),
                "metadata", metadata
        );

        System.out.println(gson.toJson(auditLog));
    }

    private void triggerHrWebhook(String userId, Map<String, Object> metadata) throws IOException, InterruptedException {
        String payload = gson.toJson(Map.of(
                "event", "USER_ACTIVATED",
                "userId", userId,
                "timestamp", LocalDateTime.now().toString(),
                "data", metadata
        ));

        HttpRequest request = HttpRequest.newBuilder()
                .uri(URI.create("https://hr-system.example.com/api/v1/users/sync"))
                .header("Content-Type", "application/json")
                .header("X-Genesys-Source", "UserActivatorService")
                .POST(HttpRequest.BodyPublishers.ofString(payload))
                .build();

        HttpResponse<String> response = httpClient.send(request, HttpResponse.BodyHandlers.ofString());
        if (response.statusCode() >= 400) {
            throw new RuntimeException("HR webhook failed with status " + response.statusCode());
        }
    }

    private double calculateSuccessRate() {
        int total = successCount + failureCount;
        return total == 0 ? 0.0 : (double) successCount / total;
    }
}

OAuth Scope Required: None (external HTTP call)
Error Handling: The webhook call throws RuntimeException on non-2xx responses. In production, implement a dead-letter queue or retry mechanism for webhook failures to prevent activation rollback.

Common Errors & Debugging

Error: 422 Unprocessable Entity

• What causes it: The user deletion date exceeds the maximum recovery window, or the user was permanently purged from the system.
• How to fix it: Verify user.getDeletionDate() against your organization’s retention policy. If the window expired, the user must be recreated manually via the admin console or by submitting a support ticket to Genesys Cloud.
• Code showing the fix: The UserValidator class explicitly checks ChronoUnit.DAYS.between() and throws IllegalStateException before the API call, preventing unnecessary network requests.

Error: 403 Forbidden

• What causes it: The OAuth token lacks user:write or license:write scopes, or the calling application is restricted by Genesys Cloud security policies.
• How to fix it: Regenerate the OAuth token with the correct scopes. Verify the application permissions in the Genesys Cloud Admin Console under Platform > Applications.
• Code showing the fix: Ensure OAuth2ClientCredentialsProvider is initialized with a client that has been granted the required scopes in the developer portal.

Error: 409 Conflict

• What causes it: A concurrent PUT operation modified the user profile during the restore iteration, causing an ETag mismatch.
• How to fix it: Implement optimistic locking by fetching the latest ETag header from the initial GET request and passing it in the PUT headers. The SDK handles ETag propagation automatically when using the domain objects.
• Code showing the fix: The UserActivator class uses SDK domain objects which automatically attach the If-Match header. If conflicts persist, implement a short delay and retry the PUT operation.

Error: 429 Too Many Requests

• What causes it: The API rate limit is exceeded during batch activation or rapid webhook synchronization.
• How to fix it: The executeWithRetry method implements exponential backoff with jitter. Adjust maxRetries and backoff multipliers based on your organization’s API tier limits.
• Code showing the fix: See the UserActivator.executeWithRetry method which catches ApiException.getCode() == 429 and sleeps before retrying.
