List approved templates for a number

Before you start

Connect your business and number in Portal → WhatsApp → Numbers & accounts first. Use an account-owner Production API key. Create templates in the Portal.

Result

Provide an IllyVoIP number_id from GET /numbers. Returns approved templates for its business with components and parameter_format so you can fill their fields. Create, edit, submit and refresh templates in the Portal. Results use cursor pagination. Legacy connection_id is accepted only instead of number_id for existing integrations.

Charges and safe retries

Inspect uncertain operations before retrying. A queued message is not delivered. IllyVoIP reserves its fee at queue admission and charges only delivered outbound messages; incoming messages are free.

Authentication

Send your account API key in the X-Api-Key header. Keep it on your server; never embed it in browser code.

Request examples

Replace the example values with your own inputs. Examples do not run on this page. Production requests can change your account or incur charges.

curl -X GET "https://app.illyvoip.com/api/v1/whatsapp/templates?number_id=YOUR_NUMBER_ID" \
  -H "X-Api-Key: ${ILLYVOIP_API_KEY:?Set ILLYVOIP_API_KEY}"

const response = await fetch("https://app.illyvoip.com/api/v1/whatsapp/templates?number_id=YOUR_NUMBER_ID", {
  method: "GET",
  headers: {
    "X-Api-Key": process.env.ILLYVOIP_API_KEY
  }
});

const data = await response.json();
console.log(response.status, data);

<?php
$ch = curl_init('https://app.illyvoip.com/api/v1/whatsapp/templates?number_id=YOUR_NUMBER_ID');
curl_setopt_array($ch, [
    CURLOPT_CUSTOMREQUEST => 'GET',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => [
        'X-Api-Key: ' . getenv('ILLYVOIP_API_KEY')
    ],
]);

$response = curl_exec($ch);
$status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

echo $status . PHP_EOL;
echo $response;

import os
import json
import requests

response = requests.request(
    "GET",
    "https://app.illyvoip.com/api/v1/whatsapp/templates?number_id=YOUR_NUMBER_ID",
    headers={
        "X-Api-Key": os.environ["ILLYVOIP_API_KEY"]
    },
)

print(response.status_code)
print(response.json())

Node.js examples run on the server (Node.js 22.17+). Python examples require requests; PHP examples require cURL. Set the environment variables referenced in each example.
