Hey Michael: Could I ask you where you got the $KEY\_ZOOM value from? I have been struggling to generate a token I can use in this context to perform API calls from within Zapier but I keep getting "The app returned “Invalid access token.”

I have been through the OAUTH token generation process but I still don’t understand where that token is supposed to come from…

Hey @philip,

The `$KEY_ZOOM` is just a variable in their code. What specially are you trying to do?

You can use [OAuth](https://marketplace.zoom.us/docs/guides/build/oauth-app) to [get an access\_token](https://marketplace.zoom.us/docs/guides/auth/oauth), or generate a [JWT Token](https://marketplace.zoom.us/docs/guides/auth/jwt) from a [JWT App](https://marketplace.zoom.us/docs/guides/build/jwt-app).

Thanks,  
Tommy
