n8n-nodes-sendiee
n8n community node for Sendiee — WhatsApp Business messaging, campaigns, AI assistants, and more via the Sendiee v2.0 API.
Wire workflow events to WhatsApp template / freeform messages, run audience-targeted campaigns, manage contacts and tags, configure AI assistants, and pull chat history — all without configuring HTTP nodes manually.
Installation
In n8n: Settings → Community Nodes → Install → search n8n-nodes-sendiee
Or via CLI:
npm install n8n-nodes-sendiee
Credentials
- Go to your Sendiee Dashboard → Settings → API Keys

- Copy your WhatsApp Business phone number (full international, no

Dynamic dropdowns ✨
Several fields are populated live from your Sendiee account so you don't have to paste IDs:
| Field | What it loads | Used in |
|---|---|---|
| Template Name | Your APPROVED templates with name + language + category | Message → Send Template, Campaign → Create |
| Tags | Your contact tags | Tag → Rename / Delete, Campaign audience |
| Custom Field | Your custom field definitions | Custom Field → Update / Delete |
| Lead Categories | Your AI lead categories | Contact → Upsert (lead_category) |
| Campaign | Your recent campaigns with status | Campaign → Get Report |
| Assistant | Your AI assistants with platform + status | Assistant → Toggle |
These call the corresponding GET /v2.0/... endpoints when you open the dropdown.
Supported Operations (v0.3)
Message
- Send Template Message · Send Freeform Message · Get Message Status
Contact
- Create or Update · Get by Phone · Filter · List All
Tag
- List · Create · Rename · Delete
Custom Field
- List · Create · Update · Delete
Template
- List · Create (strict pre-Meta validation; rate-limited)

Full assistant CRUD (create, update, restore, history) lives in the dashboard or sendiee-mcp — those are interactive setup tasks better suited to AI agents than workflow automations. Insights / billing endpoints stay in the dashboard for the same reason.
Scheduled Message
- List · Get · Cancel
