Hey @jantbarco, Your issue is because you are including special characters, `{` and `}` in your state query param. We are releasing an update this weekend to allow `{` and `}`. In the meantime you can change your state query param to not have special characters, or you can [base64 encode](https://www.base64encode.org/) or or [url encode](https://www.urlencoder.org/) your state param. Thanks, Tommy ---

Why there is no proper solution of any questions regarding zoom SDK. Every where there is a loop hole i can see. I have spent few days just checking and applying these ideas and nothing works. 1. I used authorization API --\> [https://zoom.us/oauth/authorize](https://zoom.us/oauth/authorize). Even after 200 status code, when i test the app locally at zoom marketplace, Sometime it is saying invalid redirect URL , sometime it is saying you cannot authorize the app(Although i am the admin of my zoom account) 2)I hit the API “[https://zoom.us/oauth/token](https://zoom.us/oauth/token)” and received the access\_token which is showing invalid api key while hitting GET users API /v2/users Please provide one solution. Its a complete loop hole in all answers everywhere but sadly none worked. Please help . Thanks in advance. ---
