Trigger WhatsApp from n8n with EnoSend

You don't need a dedicated EnoSend node in n8n. The built-in HTTP Request node handles everything because EnoSend is a plain REST API.

1. Add an HTTP Request node

In your workflow: + → HTTP Request. Set:

• Method: POST

• URL: https://api.enosend.com/wa/v1/messages

• Authentication: Generic Credential Type → Header Auth → Name: Authorization, Value: Bearer wa_live_YOUR_KEY

• Send Body: ON, Body Content Type: JSON

• JSON Body:

  {
    "to": "{{ $json.phone }}",
    "type": "text",
    "text": "Hi {{ $json.first_name }} — your order is ready."
  }

2. Wire a trigger

Connect any trigger to it — a Webhook node, a Google Sheets row, a Postgres notification, whatever fires the message. The expressions in the JSON body pick up fields from the previous node automatically.

3. Loop for bulk

If you have a list and want to send to all of them, two options:

1. Loop in n8n: put a Split In Batches node before the HTTP Request and iterate.

2. Use the bulk endpoint: POST to https://api.enosend.com/wa/v1/bulk with up to 500 recipients in one call. Faster and counts as one campaign in your dashboard.

4. Receive replies

Inbound flow is the mirror image: add a Webhook node, copy its production URL, paste it into EnoSend → Instance settings → Webhooks. EnoSend POSTs every inbound message there; n8n triggers your workflow.

Same pattern works for Zapier (Webhooks by Zapier action) and Make (HTTP module). Nothing EnoSend-specific to learn.
