Hi  
  
  
  
I am trying to push our live chat leads to mautic via rest api.  
  
But when i am trying oAuth1 authentication,i am getting “ **Incorrect access token parameters returned: Array** ” in the Apitester application.  
  
  
  
**In the mautic api logs, i see the below error:**  
  
mautic.ERROR: Uncaught PHP Exception SymfonyComponentHttpKernelExceptionHttpException: “signature\_invalid” at  
  
x/x/x/x/x/vendor/willdurand/oauth-server-bundle/Service/OAuthServerService.php line 174 {“exception”:"[object] (Symfony\Component\HttpKernel\Exception\HttpException(code: 0): signature\_invalid at /x/x/x/x/x/x/vendor/willdurand/oauth-server-bundle/Service/OAuthServerService.php:174)  
  
  
  
I have verified that the keys are correct and created for oAuth authentuication.  
  
Also i have mentioned the same callback URL as the url where the apitester is hosted in both the places.  
  
  
  
Please advise.  
  
  
  
Thank you  
  
Deepak

Pretty much the same error here too:

```auto
[2016-06-20 21:37:08] mautic.ERROR: Uncaught PHP Exception SymfonyComponentHttpKernelExceptionHttpException: "signature_invalid" at .../public_html/go/vendor/willdurand/oauth-server-bundle/Service/OAuthServerService.php line 244 {"exception":"[object] (Symfony\Component\HttpKernel\Exception\HttpException(code: 0): signature_invalid at .../public_html/go/vendor/willdurand/oauth-server-bundle/Service/OAuthServerService.php:244)"} []
```

This happens when making a (POST /api/leads/new) request.

Does anyone have any ideas? I’m pushed for time to get this fixed.

I think that anybody that wants to help you will need more information.

can you copy paste the code you use to authenticate to the api?

Got something very similar here, coming from a WordPress plugin for Mautic
