How to send WhatsApp messages from n8n, Make.com or Zapier

The fastest way to add WhatsApp to your automations isn't a dedicated app — it's a plain HTTP request. Every automation platform has an HTTP node, and TextMeFlow's API is one endpoint with two fields. This guide shows the exact setup for n8n, Make.com and Zapier.

Before you start

1. Create a free TextMeFlow account (50 messages/month, no credit card).
2. Scan the QR code with the phone that holds your WhatsApp number.
3. Copy your API key from the portal.

That's the whole prerequisite list — no Meta Business Manager, no template approval.

n8n

Add an HTTP Request node to your workflow:

• Method: POST
• URL: https://api.textmeflow.eu/v1/messages
• Authentication: Header Auth → name Authorization, value Bearer YOUR_API_KEY
• Body (JSON):

{
  "to": "{{ $json.phone }}",
  "text": "Hi {{ $json.name }}, your appointment is confirmed for tomorrow at 15:00."
}

Typical trigger combos: a new row in Google Sheets, a Webhook node fed by your CRM, or a Schedule node for daily reminders.

Make.com

Add an HTTP → Make a request module:

• URL: https://api.textmeflow.eu/v1/messages
• Method: POST
• Headers: Authorization: Bearer YOUR_API_KEY, Content-Type: application/json
• Body type: Raw (JSON), and map your scenario variables into to and text.

Because TextMeFlow keeps the same URL shape as TextMeBot, any existing TextMeBot scenario migrates by swapping the base URL and key.

Zapier

Use Webhooks by Zapier → Custom Request:

• Method: POST
• URL: https://api.textmeflow.eu/v1/messages
• Data: {"to": "+32479123456", "text": "Your order has shipped 📦"}
• Headers: Authorization: Bearer YOUR_API_KEY

Receiving replies

Sending is half the story. Configure a webhook in your TextMeFlow portal and every inbound WhatsApp message is POSTed to your automation platform as JSON — signed with HMAC so you can verify it's really us. In n8n and Make, that's a Webhook trigger node; in Zapier, a Catch Hook.

That unlocks two-way flows: confirmation questions ("Reply YES to confirm"), support routing, or a chatbot built entirely in your automation tool.

Keep it friendly

Automation makes it easy to send too much. Stick to messages your recipients expect, respect opt-outs (TextMeFlow handles STOP automatically), and read the anti-spam guide — it's what keeps your WhatsApp number safe.
