I am getting such errors in my Laravel project.

I am using the server-to-server auth app from Zoom

Client error: `POST [https://zoom.us/oauth/token`]([https://zoom.us/oauth/token](https://zoom.us/oauth/token)) resulted in a `400 Bad Request` response: {“reason”:“Invalid client\_id or client\_secret”,“error”:“invalid\_client”}

Hello @taalibnotes ,

Please use the guidance from our Postman workspace to generate a valid S2S token:

[https://www.postman.com/zoom-developer/workspace/zoom-public-workspace/folder/22097587-0021aa9e-17f5-478e-b106-dfb31b930153](https://www.postman.com/zoom-developer/workspace/zoom-public-workspace/folder/22097587-0021aa9e-17f5-478e-b106-dfb31b930153)

The workspace is correctly set up and can help you identify errors in your code base.
