QR Codes API

Overview

Create, list, update, and delete QR codes for prefilled messages.

Endpoints

• POST /{PHONE_NUMBER_ID}/message_qrdls
• GET /{PHONE_NUMBER_ID}/message_qrdls
• GET /{PHONE_NUMBER_ID}/message_qrdls/{QR_CODE_ID}
• POST /{PHONE_NUMBER_ID}/message_qrdls
• DELETE /{PHONE_NUMBER_ID}/message_qrdls/{QR_CODE_ID}

Notes

• prefilled_message is the text users see when opening the chat.
• generate_qr_image can be set to PNG for image output.

Example

import WhatsApp from 'meta-cloud-api';

const client = new WhatsApp({
  accessToken: process.env.CLOUD_API_ACCESS_TOKEN!,
  phoneNumberId: Number(process.env.WA_PHONE_NUMBER_ID),
  businessAcctId: process.env.WA_BUSINESS_ACCOUNT_ID!,
});

const created = await client.qrCode.createQrCode({
  prefilled_message: 'Hello from QR',
  generate_qr_image: 'PNG',
});

const list = await client.qrCode.getQrCodes();
const detail = await client.qrCode.getQrCode(created.id);

await client.qrCode.updateQrCode({
  code: created.code,
  prefilled_message: 'Updated message',
});

await client.qrCode.deleteQrCode(created.id);

Example Details

• createQrCode uses prefilled_message and generate_qr_image to return a code.
• getQrCodes lists all codes; getQrCode fetches one by ID.
• updateQrCode uses the code string from create, while deleteQrCode uses the numeric ID.
