Hi I'm trying to send a webrequest, but it says error code: 5203

I searched so much on the internet but i couldn't find something that resloves this. I added the "http://localhost" permission on the setting, but it's not the problem.

It doesn't work neither with GET, or POST


I have already added the api_url to the list of allowed URLs in the configuration.


Can anyone spot where is the error please?

I suggest you check with the Web servers logs...

It's impossible to tell with only one half/side of the code.

Also, print out the parameters to WebRequest, such that you can reconstruct the request with a tool like curl or with a browser and the dev console.

Then make your web server log all requests.

This way you might find out what's going on.

Usually it's a malformed request that you are sending.
