Descripción
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.

- 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

FAQ
-
What is a WordPress action?
-
An action is a WordPress hook triggered at a specific moment, such as when a user is created, a post is saved, or an order is completed.
-
Can I use this plugin with n8n?
-
Yes. This plugin works seamlessly with n8n webhook triggers and is designed with automation workflows in mind.
-
Does this plugin support WooCommerce hooks?
-
Yes. Any WooCommerce action can be used as a trigger, as long as the hook is available.
-
How does the retry mechanism work?
-
Failed webhooks are automatically retried using exponential backoff. The delay increases with each attempt (e.g., 1 minute, 2 minutes, 4 minutes, 8 minutes), up to a maximum delay of 1 hour between retries. By default, 5 attempts are made before marking a job as failed. The retry behavior can be adjusted using available filters.
-
What is Payload Mapping?
-
Payload Mapping allows you to transform the webhook payload before it is sent. You can rename fields, reorganize the structure, or exclude sensitive data. The plugin can store example payloads to help configure mappings.
-
Can I include user data in webhook payloads?
-
Yes. For user-related triggers (such as
user_register,profile_update,wp_login,wp_logout), you can enable "Include User Data" to automatically add user information (ID, email, display name, roles, etc.) to the payload. -
Is this plugin free?
-
Yes. The plugin is completely free and licensed under GPL.
