About This Workflow
Overview
This template demonstrates how to send a message to multiple destinations simultaneously (fan-out) and then combine their responses (merge). It's useful for broadcasting notifications or messages to various platforms or services at once and processing their acknowledgments or data.
Key Features
- Triggers via a webhook to receive a message payload.
- Prepares the message for broadcasting.
- Sends the message to multiple HTTP endpoints (simulating different channels) in parallel.
- Merges the responses from all broadcast operations.
- Responds to the initial webhook request with the merged results.
How To Use
- Import this workflow into your n8n instance.
- Configure the
Webhooknode's path to your desired endpoint (e.g.,/template/broadcast). - Update the
Broadcast AandBroadcast Bnodes (and add more if needed) with the actual URLs and payload structures for your target channels. - Modify the
Prepare Messagenode to dynamically set message content and channel identifiers if required. - Trigger the webhook with a POST request containing a JSON body with a
messagefield.
