How to send WhatsApp messages from Make

1. Get your credentials

Sign up at flowapi.pro, create a number and scan the QR code from WhatsApp → Settings → Linked devices. Copy the Instance ID and API Token from the Credentials tab.

2. Add the HTTP module

1. 1In your scenario add HTTP → Make a request.
2. 2URL: https://flowapi.pro/waInstance{idInstance}/sendMessage/{apiTokenInstance}
3. 3Method: POST. Body type: Raw. Content type: JSON (application/json).

3. Write the body

{
  "chatId": "{{1.phone}}@c.us",
  "message": "Hi {{1.name}}, thanks for your order!"
}

4. Run once

Click Run once. A 200 response with an idMessage means the message was sent. A 401 means the instance ID or token is wrong; a 402 means the trial ended or the number is not covered by your plan.

5. Send a file instead

Change sendMessage to sendFileByUrl in the URL and send {"chatId": "…", "urlFile": "https://…/file.pdf", "fileName": "file.pdf", "caption": "…"}.
