Obtaining authorization token with code flow

[sbartan]

I'm trying to obtain authorization token with code flow. I'm using spatie/flysystem-dropbox in laravel. I'm redirected to my site, with code parameter in url, but i can't get my token.

I recieve this error: 

{"error_description":"No auth function available for given request","error":"invalid_request"}

The "No auth function available for given request" error should indicate that the excepted parameters for this call were not supplied correctly in the HTTPS request to /oauth2/token.

It looks like you're providing the necessary variables, but they may not be getting sent in the right way. How is the array in that second parameter to Http::post getting formatted and sent? The parameters for /oauth2/token should be sent as application/x-www-form-urlencoded POST parameters. 

Are you able to print out the raw HTTP request? That may be useful for debugging this. We can't provide support for third party clients, platforms, or libraries though, such as spatie/flysystem-dropbox or Laravel, so I can't offer guidance on exactly how you'd do so. You may need to refer to the relevant documentation for that.

Hi @sbartan,

Have you read "Request Data" documentation carefully? Make note on:

By default, data will be sent using the application/json content type

Little bit below could be seen:

If you would like to send data using the application/x-www-form-urlencoded content type, you should call the asForm method before making your request

Hope this helps. 😉

Thanks @Здравко, it's working now!
