Hello Joe,

Unfortunately, connecting your site to my own Zoom App didn’t solve the issue. However, I checked the database and found this message in the bookly\_zoom\_oauth\_token option:

Your request is blocked by security policy.(SupportId: 18398479702038370138)  
Please contact Zoom support team and ask about this issue.  
Best regards,

Hello Joe,

Thank you for your quick reply.  
Could I temporarily set my own Zoom API keys to check the issue?
