# Token error: invalid_client When entering API Details

 * I’m very interested in trying out this plugin (if it works well, upgrade to premium)
   but when I click test connection with my api details it just says Token error.
   My credentials are correct and I even regenerated them to see if those worked.
 * Does this plugin work with the current creator api (v3.1)? The video showed 2.1.
 * The credential id also starts with amzn1.application-oa2-client. which wasn’t
   shown in the video.

 * Hi [@ds55](https://wordpress.org/support/users/ds55/)
 * Thanks for your input, the plugin is updated to support the 3.x creators api 
   version. update your version and you should be good to go.
