I have referred to the following link for development.

> **[App Base Guide](https://developer.shopware.com/docs/guides/plugins/apps/app-base-guide)**

I have received the API key and API secret from the extension installation response but I am unable to generate the access token using them, but if I create an access key manually that key is generating the O Auth is there some step I am missing or settings I might have changed, because this use to work before. But now I am getting the following error.

[OAuth Generation Error](https://i.stack.imgur.com/RrJ4m.png)

Received Client Id and Client Secret using Extension install response.

But these using these credentials I am not able to generate the OAuth token.

API response :  
{  
„errors“: [  
{  
„code“: „4“,  
„status“: „401“,  
„title“: „Client authentication failed“,  
„detail“: null  
}  
]  
}
