Hi,

I am trying to integrate Zoom meetings with my php application, for integration using Zoom API. when I am sending a request to Zoom server to create a meeting getting {“code”:124,“message”:“Invalid access token.”} error. I have also verified token in “[https://jwt.io](https://jwt.io)”. but not working in my application.  
I am able to successfully create a meeting with same API key and API Secret in my another wordpress application but not working in my custom application.

I am using free basic trial account in zoom.

Please help me.

Thanks.

Hey @tiwari.jyoti.05,

How are you setting the authorization header? If it is working on another application, but not on yours, there must be something off with how you are sending the request or generating the JWT Token.

Thanks,  
Tommy

Hey @tiwari.jyoti.05,

I am not an expert in PHP so please try referencing PHP documentation or stack overflow.

You can also use one of the PHP libraries listed here to generate a JWT:

> **[JWT.IO](https://jwt.io/)**
>
> JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.

Thanks,  
Tommy
