Hello, when I was making the app, I started debug. After that I noticed that I always have a network error error when attempting to fetch resource. No matter how I spin, it does not help. ![изображение](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/8/a8a56bb4ee9188c5d2012cd5d6b0c893a87807b5.png) That’s all the report I have. ![изображение](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/4/e4c0b0988486f62bdfb19abbadc3ed905144bbe9.png) Blocks ---

If you’re getting a network error in a third-party client like Postman or in a browser as a url, then that has nothing to do with your blocks in Thunkable. Are you able to use the full url in a browser (e.g. Chrome) and have it work successfully? That’s the first step when wanting to use an API in Thunkable. **Edit:** I think your full url is api.php?url=[https://www.ya.ru](https://www.ya.ru). That works and returns [https://ulvis.net/4u9I](https://ulvis.net/4u9I) in a browser. Is this a url-shortening service? Also, what is the exact `error` you’re getting in Thunkable? Make sure you’re testing it on a mobile device. You’re not displaying the `response` so you might want to do that just in case it _does_ work. ---

Yes, this is a service to shorten the URL. I enter in the browser, and there is an exact error as from the header. And the network shows that the CORS request failed. I did not test on mobile, but I’ll look at it now… ---

It works on mobile, but I want it to work on a web-based. This is important! ---

If you want web based youll need to proxy your api calls. The Thunkable web app infrastructure will cause these api call issues. On a mobile device, there’s no Cors issue. ---
