Flow Systems Webhook Actions

Flow Systems Webhook Actions is a WordPress webhook plugin that lets you trigger HTTP webhooks from any WordPress or WooCommerce action (do_action).

Instead of writing custom integration code, you can configure webhook endpoints directly from the admin panel and send structured JSON payloads to automation tools or external APIs.

Webhooks are dispatched asynchronously with background processing, retry logic, and delivery logging to ensure reliable and non-blocking execution.

Typical use cases

• Send WooCommerce order data to n8n
• Sync new WordPress users to a CRM
• Trigger Slack notifications when a post is published
• Send form submissions to an external API
• Automate membership or subscription workflows
• Connect WordPress events to internal backend systems

Webhook Triggering

• Trigger webhooks from any WordPress action (do_action)
• Support for core, custom, and WooCommerce hooks
• JSON payload including hook name, arguments, timestamp, and site URL
• Configurable webhook URL and optional Authorization header
• HTTPS enforcement by default (configurable via filter)

Queue System

• Asynchronous background processing via WP-Cron
• Non-blocking execution to avoid slowing down user requests
• Automatic retry with exponential backoff

Payload Mapping

• Transform payload structure before dispatch
• Rename fields using dot notation
• Exclude selected fields from webhook payload
• Restructure payload to match external API requirements
• Store example payloads to assist configuration
