✔ YES

Stop it via Services.msc or disable startup to stop automatic runs

What is api-client-sync-service.exe?

api-client-sync-service is a background Windows service responsible for coordinating API credential synchronization, token refreshes, and data updates across multiple installed applications. It runs without user interaction to keep configurations consistent.

The service runs as a lightweight daemon that watches config changes, performs secure API calls, and reconciles data across apps. It operates under a system account and uses TLS with retry/backoff for reliability.

Quick Fact: API Client Sync Service supports multi-source synchronization and token renewal without manual prompts.

Types of api-client-sync-service Processes

Service Host Process: Main api-client-sync-service instance managing orchestration
Credential Refresh Task: Handles token renewal and credential updates
Data Sync Worker: Performs data reconciliation across apps
Endpoint Monitor: Watches API endpoints for changes and health
Telemetry & Health: Sends status and health reports to the admin panel
Background Scheduler: Schedules sync windows and backoff strategies

Is api-client-sync-service Safe?

Yes, api-client-sync-service is safe when obtained from legitimate sources and installed by approved software from your organization or vendor.

Is api-client-sync-service a Virus or Malware?

The real api-client-sync-service is NOT a virus. Malware may mimic names, so verify the executable path and digital signature.

How to Tell if api-client-sync-service is Legitimate or Malware

File Location: Must be in C:\Program Files\ApiClientSync\ or C:\Program Files (x86)\ApiClientSync\. Any other location is suspicious.
Digital Signature: Right-click api-client-sync-service.exe in the installation directory -> Properties -> Digital Signatures. Should show vendor like "API Solutions, Inc."
Resource Usage: Normal usage is 0-5% CPU, 20-120 MB memory. Constant high usage outside active syncs is suspicious.
Behavior: Should run as a Windows service and not launch manually from user directories.

Red Flags: If api-client-sync-service.exe appears in unusual folders (Temp, AppData, or user downloads), runs when not expected, lacks a valid signature, or shows persistent high resource usage, scan with antivirus and compare with the official publisher.

Why Is api-client-sync-service Running on My PC?

api-client-sync-service runs to maintain synchronized API credentials, tokens, and related data across installed apps. It may also start at system boot to ensure ready access to APIs.

Reasons it's running:

Active Data Synchronization: A configured sync job is active, reconciling credentials and data between local apps and remote services.
Background Token Refresh: Periodic token renewal occurs so apps retain valid API access without user action.
Startup and Scheduled Runs: The service can start on boot or at scheduled windows to perform nightly or periodic syncs.
New App Integrations: New apps or modules added to the suite trigger additional sync tasks.
Health & Configuration Checks: Regular checks ensure endpoints are reachable and configuration files are intact.

Can I Disable or Remove api-client-sync-service?

Yes, you can disable api-client-sync-service. It is safe to stop the service if you do not want automatic synchronization, and you can uninstall the component if you no longer need it.

How to Stop api-client-sync-service

Stop the Service: Open Services.msc, locate 'Api Client Sync Service' and click Stop.
Disable Automatic Start: In Services.msc, set Startup type to Disabled to prevent auto-start.
Prevent Background Tasks: In the host application, turn off background sync or disable related tasks if available.
Uninstall the Service: Go to Settings > Apps & Features and uninstall 'Api Client Sync' or use the vendor's uninstaller.
Remove Residual Data: Delete C:\Program Files\ApiClientSync and clear related AppData if necessary.

How to Uninstall api-client-sync-service

✔ Windows Settings -> Apps -> Apps & Features -> Api Client Sync -> Uninstall
✔ Control Panel -> Programs -> Uninstall a program -> Api Client Sync -> Uninstall
✔ Run the vendor's uninstaller if available and restart the system

Common Problems: High CPU or Memory Usage

If api-client-sync-service is consuming excessive resources:

Common Causes & Solutions

Frequent credential refresh: Check token expiration settings and enable backoff to reduce CPU usage during renewals.
Large data payloads during sync: Tune batch sizes, filter unnecessary data, and stagger sync windows.
Misconfigured endpoints: Verify API base URLs, TLS settings, and certificate validation in the config.
Excessive polling: Switch to event-driven or scheduled sync rather than constant polling.
Outdated software: Update to latest version and apply all security patches.
Conflicting extensions or apps: Disable or remove non-essential integrations and isolate the service.

Quick Fixes:
1. Open Services.msc and restart the Api Client Sync Service to regain a clean state
2. Review recent sync logs in Event Viewer or the vendor's admin console
3. Reduce active sync payloads by filtering data and disabling non-essential integrations
4. Update to the latest version via vendor or Windows Update
5. Enable scheduled or event-driven sync instead of continuous polling

Frequently Asked Questions

Is api-client-sync-service safe?

Yes, api-client-sync-service is safe when obtained from legitimate sources. Verify the executable path and digital signature in the installation directory (e.g., C:\Program Files\ApiClientSync\) and ensure the publisher matches the vendor.

Why is api-client-sync-service running in the background?

It runs to maintain synchronized API credentials, tokens, and data for your apps. Background syncing allows instant updates but can be configured to run on demand or a schedule.

Can I disable api-client-sync-service without breaking apps?

Disabling the service will stop automatic synchronization. Applications that rely on API tokens or config data may require manual refreshes or re-authentication after disabling.

Where is api-client-sync-service installed?

Typically under C:\Program Files\ApiClientSync or C:\Program Files (x86)\ApiClientSync. The exact path depends on the installer used by your organization.

How do I uninstall api-client-sync-service?

Use Windows Settings > Apps & Features or Control Panel > Programs to uninstall. If part of a larger client suite, use the suite's uninstaller to ensure all components are removed.

What happens if I disable or uninstall?

Disabling stops automatic syncs. Uninstalling removes the service and related data. You may need to reconfigure apps or re-authenticate after reinstallation.

Can api-client-sync-service affect performance?

Yes, near-constant token renewals and large payload syncs can impact CPU and memory. Adjust configurations, enable backoff, and schedule syncs during low-usage periods.
