Enabling domain synchronization in WHMCS ensures that the platform regularly communicates with your domain registrar to keep track of domain statuses, expiry dates, and other related information. This feature is crucial for accurately managing domain registrations and renewals.

Here's how you can enable domain synchronization in WHMCS:

1. Log into WHMCS: Access your WHMCS admin panel using your username and password.

2. Navigate to Configuration: Click on the "Configuration" tab in the top navigation menu.

3. Domain Registrars: Under the "System Settings" section, click on "Domain Registrars."

4. Edit Registrar Settings: Find the registrar for which you want to enable domain synchronization and click on the "Edit" icon (pencil icon) next to it.

5. Sync Settings Tab: In the registrar settings, look for a tab or section related to domain synchronization. This can vary depending on the registrar.

   • Registrar-Specific Settings: Each registrar may have different options for domain synchronization. These settings typically include options like enabling/disabling domain syncing, setting the sync frequency, and configuring advanced sync options.

   • Sync Enabled: Check the box labeled "Enable Domain Synchronization" or a similar option. This enables WHMCS to communicate with the registrar and keep domain information up to date.

   • Sync Frequency: Set how often WHMCS will check with the registrar to update domain statuses.

6. Save Changes: After enabling domain synchronization, click the "Save Changes" button to apply your modifications.

7. Repeat for Other Registrars (if needed): If you have multiple registrars, repeat the above steps for each one.

Keep in mind that domain sync settings can vary depending on the specific registrar and the integration with WHMCS. Be sure to review any documentation or support resources provided by your registrar for specific guidance on configuring domain synchronization.
