Webhook Trigger

This package provides a Chatwork Trigger node that allows n8n workflows to receive events from Chatwork via webhooks.

Supported Events

The trigger node listens to incoming Chatwork webhook events and routes them to different outputs:

| Event Type | Output | |-------------------|-----------------| | mention_to_me | Mention To Me | | message_created | Message Created | | message_updated | Message Updated |

Webhook Security

Chatwork signs webhook requests using an HMAC-SHA256 signature.

The Chatwork Trigger node supports optional signature verification using one or more webhook tokens:

• Signature header: x-chatworkwebhooksignature
• Hash algorithm: HMAC-SHA256
• Secret key: Base64-decoded webhook token

Signature verification can be disabled for local development and testing.

Each output can be connected independently in your workflow.

Development Notes

• The workflow must be active for webhooks to be registered
• Webhooks will return 404 – unknown webhook if the workflow is inactive
• Signature verification should be disabled when testing with manual curl requests

Known Limitations

• Webhook events are currently processed as-is
• Duplicate or replayed webhook events are not yet deduplicated
• Replay protection and idempotency will be added in a future release

Credentials

This node requires a ChatWork API Token.

Prerequisites

• A ChatWork account
• An API token generated from your ChatWork account settings

Setup

1. In n8n, go to Credentials
2. Create new credentials of type ChatWork API
3. Paste your ChatWork API token
4. Save the credentials and select them in the ChatWork node

Authentication is handled via the X-ChatWorkToken request header.

Compatibility

• Minimum n8n version: 1.x
• Tested with: n8n 1.x (community nodes API v1)

This node uses the new routing-based request system introduced in n8n v1. Older n8n versions are not supported.

Usage

Most operations are straightforward and map directly to ChatWork API endpoints.

Notes:

• Boolean options such as Create download URL control optional API query parameters.
