Hello everyone,

I’ve decided to implement the ZOOM API into my application, which is still in development mode, but I’m having a problem. I’ve followed the instructions from this tutorial [https://www.youtube.com/watch?v=MC\_RVGAKQZ4&list=LL&index=2](https://www.youtube.com/watch?v=MC_RVGAKQZ4&list=LL&index=2) and I managed to generate an Access Token. However, when I call the endpoint **[https://api.zoom.us/v2/users/me/meetings](https://api.zoom.us/v2/users/me/meetings)**, I get an error:

{  
“code”: 124,  
“message”: “Invalid access token.”  
}

The token is in the header, can anyone tell me where I’m making a mistake?

Fixed 🙂

I didn`t put Bearer on Header Prefix

Hello @elisa.zoom sorry for writing you like this but we (from development side) are in little bit of rush can you please check my question [Is alternative host same as licence from business plan?](https://devforum.zoom.us/t/is-alternative-host-same-as-licence-from-business-plan/92880) and just confirm me if this is correct so we can buy the package and continue with development 🙂

Thank you !
