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

1. Go to your Sendiee Dashboard → Settings → API Keys
2. Copy your API key
3. Copy your WhatsApp Business phone number (full international, no +)
4. In n8n: Credentials → New → Sendiee API → paste both

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)

Campaign

• Preview Audience (always preview before sending) · Create (immediate or scheduled) · List · Get Report (delivery + engagement + cost breakdown)

Chat

Assistant

• List (filter by platform / active / connected) · Toggle (enable / disable)

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

Example Workflows

• Shopify order confirmed → Send WhatsApp template with order details (templateName picker auto-loads APPROVED templates)
• CRM lead tagged "VIP" → Preview campaign audience → Create campaign to those VIPs with a personalised template
• Daily 9 AM cron → List chat conversations → Mirror unread to Slack
• Out-of-hours webhook → Toggle assistant → Disable replies (and re-enable in the morning)
• Typeform submission → Upsert contact (with loadOptions-driven lead category) → Send welcome template
