@inutil-labs/n8n-nodes-whin

Whin for n8n – send WhatsApp messages to yourself (alerts, status, outcomes) with the simplicity of a token. No Meta Business Manager, no phone number onboarding, no app review.

• No base URL to configure
• Single credential: Token
• Supports WhatsApp content types: text, template, image, audio, video, document, sticker, contacts, location, interactive.
• v1.0 scope: Sender node only (no trigger/receiver)

Quickstart

• Install in n8n → Settings → Community Nodes → Install → @inutil-labs/n8n-nodes-whin
• From WhatsApp, send token n8n to the Whin8n number to receive your token
• Create credentials: Whin API → paste token
• Add the Whin node and set Content Payload to your WhatsApp content object (no envelope)
• Execute → message is delivered to your own WhatsApp

How Whin works

Whin wraps WhatsApp Cloud so you can message yourself from n8n without the usual Meta setup. A short‑lived token (free plan: 24h) authenticates you and implicitly selects your registered number. Because you’re sending to yourself, there is no to field.

Get your token

• From your WhatsApp, send a message to the Whin8n number: 1 302 360 1140
• Text exactly: token n8n
• You’ll receive a reply containing your token and whin8n contact card.
• Use that token in the node’s credentials (renew the same way when it expires)

Notes

• The token binds your requests to your WhatsApp number – do not include to.
• On expiration, the backend will respond asking you to renew.

Installation

The easiest way is through the n8n UI.

• In n8n: Settings → Community Nodes → Install
• Package name: @inutil-labs/n8n-nodes-whin
• Approve and restart when prompted

For advanced/self‑hosted options, see n8n docs: Install community nodes

Configure and send

• Create credentials: Whin API

• Token: paste the token you obtained via WhatsApp (token n8n)

• Add node: Whin (subtitle includes “WhatsApp • send to yourself”)

• Content Payload: the WhatsApp content object only (no envelope). The node strips messaging_product, to, and context if present.
• Token Override (optional): per‑item token
• Request Timeout (ms): default 10000

• Execute

• The node posts your content to Whin and returns delivery info. If the token expired, you’ll get a renewal hint.

Content Payload rules (important)

• Do NOT include: messaging_product, to, context
• Include only the content object with a valid type:
  • text|template|image|audio|video|document|sticker|contacts|location|interactive|reaction

Using expressions

• Use previous item JSON:

{{$json}}

• Use a nested field (e.g., whatsappContent):

{{$json.whatsappContent}}

• Build content dynamically:

{{ { type: 'text', text: { body: $json.message } } }}

• Parse a JSON string:

{{ JSON.parse($json.payload) }}

Token lifecycle

• Free plan tokens expire in 24h
• Renew by sending token n8n to 1 302 360 1140

Example use cases

• Alerts: build complete, server metrics, failed job, new order
• Flow outcomes: invoice sent, PR merged, backup finished
• Daily digests and reminders

Troubleshooting

• Node not listed: ensure Community Nodes are allowed by your n8n instance and you installed @inutil-labs/n8n-nodes-whin
• 401/expired: renew the token via WhatsApp (token n8n)
• Payload error: send the content object only; include a valid type

Security

• The token is stored as a masked credential
• The node strips envelope fields (messaging_product, to, context) to avoid accidental leakage
