How can I make a request (POST/GET) to Shopify App from an external server?

[rousnay]

Hi, I am new to Shopify App development, but I have to build a fairly complex app on top of NodeJS and ReactJS. I got stuck with receiving webhook notifications from an external server. I have developed a POST API endpoint in my app to work as a webhook receiver. But the problem is that I need help accessing the API's endpoint (built in the app) from outside the Shopify store.

API endpoint of my app is:
https://app_url/api/notification_reciever

I also have set up an App proxy like this:
https://app_url/proxy_route/api/notification_reciever

And I can access the endpoint from the theme:
https://store_url/api/notification_reciever

How can I access the API endpoint from the outside world with the POST/GET method? I am eagerly waiting for help; any tips are valuable to me in this regard.

Thanks in advance 🙂

Hi Rousnay! 

Great to hear you're working on a Shopify app project! Where is the app currently hosted? If you want to be able to make API calls you should ensure that your app's API endpoint is hosted on a publicly accessible server. When you make a post request to https://app_url/api/notification_reciever what are you seeing? 

Hope this helps!

Hi thank you for your reply,

I am getting "No shop provided", as a response:

My code is below:

app.post("/api/notification_reciever", async (_req, res) => {

const payload = _req.body;

const fulfillment = await shopify.api.rest.Fulfillment({session: res.locals.shopify.session});

fulfillment.line_items_by_fulfillment_order = [

{

"fulfillment_order_id": payload?.id

}

];

fulfillment.tracking_info = {

"number": payload?.tracking_number,

"url": payload?.tracking_url

};

await fulfillment.save({

update: true,

});

res.json("Fulfillment notification recieved!");

res.status(200).end();

});

Thanks again Liam 🙂
