Get QR Code (JSON) Guide

This endpoint allows you to retrieve the WhatsApp pairing QR Code in JSON format. This format is ideal if you want to build your own custom dashboard where users can scan the QR directly from your custom interface.

Pro Tip: Real-time UI

Use this endpoint within a polling mechanism (e.g., every 20-30 seconds) on your frontend to display the latest QR Code until the status changes to ALREADY_LOGGED_IN.

Response Structure

The response will include a base64 string that can be displayed directly in an <img> tag.

Field	Type	Explanation
status	string	success or error
message	string	Status message (e.g., ALREADY_LOGGED_IN)
data.qr_code	string	Base64 string with the prefix data:image/png;base64,...

Implementation Example (React)

const fetchQR = async () => {
  const res = await fetch(`https://api.wagy.web.id/api/v1/${DEVICE_ID}/auth/qr/json`, {
    headers: { 'Authorization': `Bearer ${TOKEN}` }
  });
  const json = await res.json();
  if (json.data?.qr_code) {
    setQrImage(json.data.qr_code);
  }
};
