Hello guys,

I tried to get the access token via Postman. When I post the request. I’m getting the following error:

 ![Token](https://global.discourse-cdn.com/free1/uploads/keycloak/original/2X/5/5bf820cf2628147b89d316a921c0091b22b56580.png)

I use the following post url: {Domain}/auth/realms/{realmname}/protocol/openid-connect/token

Maybe I’m missing something or you can help me with that problem.

Best regards

Matthias
