Hey guys!

I’m receiving the error “Status code 401 {“code”:124,“message”:“Invalid access token.”}” when calling any API and I would like to find the error.

I’ve tried to connect using OAuth and Server-to-Server application and both cases I have the same behavior.

The goal is to connect the account of each app user (team account), and another user type (sales rep) will schedule a meeting with the connected account. It’s an app that we onboard teams, and connect their Zoom accounts and allow sales reps schedule calls with the team.

Something like Calendly. Set some available spots and allow users to grab a time on this schedule.

Thanks,  
Vinicius Andrade
