[### Website URL](http://kutalmisberkejrtest.free.nf/) Hello, I have never used a hosting service before, so my questions might be a little weird, sorry in advance 🙂 I am trying to build a PHP API server which will have a React frontend. It’s an entry level task so I’m not allowed to use any frameworks and such for backend, therefore I had to use my react client as a separate view component which sends ajax(axios) requests to the server (POST,GET and DELETE, I’ve designed it as a RESTful api) Anyways, I managed to host the backend but I have a couple of issues so far. I can’t get or post data using POSTMAN and my frontend application. It throws CORS errors, which I’ve had before but managed to fix them in localhost. But I got no idea what to do in here. ### Error Message Access to XMLHttpRequest at ‘URL\_Name’ from origin ‘LOCALHOST’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. I’ve read that this is intended to a degree, but is there anyways to overcome this issue? As I said, I fixed the issue on localhost but I’m not really sure how to approach in here. Also, If I use different parameters and methods (like URL\_Name/products/display), I receive: 500 Internal Server Error #### Something on the website crashed! Any help would be greatly appreciated. Thanks ---

Hi there, Building APIs violates the our ToS, and is thus blocked by this: > [@Ensuring only web browsers can access your website](https://forum.infinityfree.com/t/ensuring-only-web-browsers-can-access-your-website/49353): > > InfinityFree is a website hosting service.

Another possible apporach is to use a custom domain with Cloudflare, which will bypass the security system, but I’ve never tested it, and doing it here still violates the ToS. ---

You can build a Single Page Application with a PHP API here, but there are some restrictions. The most notable ones are: - Our hosting blocks CORS requests. This means the frontend and the backend must be hosted on the same hostname. If the backend is on [www.example.com](http://www.example.com), the backend must also be on [www.example.com](http://www.example.com). Hosting the backend on, say, [api.example.com](http://api.example.com), or testing the frontend locally, will result in the requests getting block. - Our hosting only allows the GET and POST HTTP methods. Other methods, such as PUT, PATCH and DELETE, are blocked. > [@anon70622800](#): > > Also, If I use different parameters and methods (like URL\_Name/products/display), I receive: > > 500 Internal Server Error #### Something on the website crashed! A 500 error is usually the result of a PHP code crash. If changing API parameters causes this, I’m pretty sure that your PHP code is just unable to handle those parameters. ---

Thank you for your response. > [@Admin](#): > > Our hosting only allows the GET and POST HTTP methods. Other methods, such as PUT, PATCH and DELETE, are blocked DELETE and PUT method being blocked is a bummer, I need to find an alternative in this case then. I can debug other errors but I need a way to some make alterations for my list items etc… Are methods in question blocked on premium as well? ---

> [@SpookyKipper](#): > > `htaccess` file with the following content: > `Header set Access-Control-All` Thank you, I know that but I tend to listen to owner who says CORS requests are blocked, and hosting a React frontend and a PHP backend under same name doesn’t seem intuitive because of different enviroments, what do you think? ---
