register webhooks on nodejs when order created - node.js

Question

I have a shopify store mystore and I have an nodejs app myapp. I need to do is when something happens on mystore a webhook will be created/registered in my nodejs app. I have tried https://www.npmjs.com/package/#shopify/koa-shopify-webhooks this package but it is not working for me and I don't think that it is the same thing that I want. I just want that when let suppose order is created in store a webhook is registered.

if you just have to register a webhook you can use this code.
You just have to change the webhook topic and the endpoint.
This is for orders/create webhook registration
add shopify-api-node and request-promise packages and require them
const ShopifyAPIClient = require("shopify-api-node");
const request = require("request-promise");
then
const createOrderWebhook = await registerWebhook(yourShopDomain, yourShopAccessToken, {
topic: "orders/create",
address: "Your node app end point" //www.example.com/webhooks/createOrder,
format: "json",
});
add your registerWebhook function
const registerWebhook = async function (shopDomain, accessToken, webhook) {
const shopify = new ShopifyAPIClient({
shopName: shopDomain,
accessToken: accessToken,
});
const isCreated = await checkWebhookStatus(shopDomain, accessToken, webhook);
if (!isCreated) {
shopify.webhook.create(webhook).then(
(response) => console.log(`webhook '${webhook.topic}' created`),
(err) =>
console.log(
`Error creating webhook '${webhook.topic}'. ${JSON.stringify(
err.response.body
)}`
)
);
}
};
for checking the webhook already not created at Shopify you can use following code
const checkWebhookStatus = async function (shopDomain, accessToken, webhook) {
try {
const shopifyWebhookUrl =
"https://" + shopDomain + "/admin/api/2020-07/webhooks.json";
const webhookListData = {
method: "GET",
url: shopifyWebhookUrl,
json: true,
headers: {
"X-Shopify-Access-Token": accessToken,
"content-type": "application/json",
},
};
let response = await request.get(webhookListData);
if (response) {
let webhookTopics = response.webhooks.map((webhook) => {
return webhook.topic;
});
return webhookTopics.includes(webhook.topic);
} else {
return false;
}
} catch (error) {
console.log("This is the error", error);
return false;
}
};
Happy coding :)

You can not create/register a new webhook when the order created.
Webhooks are a tool for retrieving and storing data from a certain event. They allow you to register an https:// URL where the event data can be stored in JSON or XML formats. Webhooks are commonly used for:
Placing an order
Changing a product's price
Notifying your IM client or your pager when you are offline
Collecting data for data-warehousing
Integrating your accounting software
Filtering the order items and informing various shippers about the order
Removing customer data from your database when they uninstall your app
