SoftArt Post Sync Webhook

Sync posts, pages, and custom post types between WordPress sites using secure webhooks.

Description

WP Post Sync Webhook allows you to automatically sync content between two or more WordPress sites. When you publish or update a post on the sender site, it automatically appears on the receiver site.

Perfect for agencies, content networks, and multi-site publishers who need to distribute content across multiple WordPress installations.

✨ Features

• Featured Images - Featured images are synced with alt text and captions
• Content Images - All images within post content are synced
• Smart Image Matching - Avoids duplicate downloads by matching existing images
• Categories & Tags - Taxonomies are synced and created if needed
• Custom Fields - Post meta data is synced
• Secure - Uses HMAC-SHA256 signatures for webhook verification
• Custom Post Types - Sync any public post type
• Manual Sync - Manually sync specific posts when needed
• Health Check - Verify connection status between sites
• Beautiful Admin UI - Modern, intuitive settings panel

Frequently Asked Questions

Can I sync between more than two sites?

Yes! You can set up multiple sender sites pointing to one receiver, or configure a site as "Both" to send and receive.

Does it sync existing posts?

By default, only new or updated posts are synced. Use the "Manual Sync" feature to sync existing posts by entering their post ID.

What happens if the receiver site is down?

The sync will fail silently. Check the debug log for error messages. The post will sync on the next update.

Is it secure?

Yes. All webhooks are signed with HMAC-SHA256 and verified using a shared secret key. Without the correct secret key, webhooks are rejected.

Does it work with page builders?

Yes, the post content is synced as-is, including page builder shortcodes and blocks. Images are also imported and URLs are updated.

Will it create duplicate images?

No! The smart image matching system checks if an image already exists before downloading. It matches by source URL, file hash, filename, and file size.

Can I sync custom post types?

Yes, you can select which post types to sync in the settings panel.
