Invalid OAuth Request.

[Stanislav]

Hello.
I am unable to communicate with your API over OAuth, because I got always error:
HTTP error 401. Raw Provider API response: Invalid OAuth Request.

I send all necessary parameters, but not transfered to show login screen.

What language and oauth library are you using?

[Stanislav]

PHP and Hybridauth. I can send you debug info to email if you want.

Maybe pasting your code here would be easiest (remember to remove your api keys and secrets!).

I am having the same problem. I am hitting a signed url with every required parameter but getting 401. What's more surprising is that the same url gives perfect data when hit from a REST client such as Postman. I am using C# (HttpClient)
