Error using book appointment feature for cal.com

Hi everyone,

I am building an inbound call agent. I am able to add the function ‘check_availability’ from cal.com with the API key and eventid but can’t do it for the ‘book_appointment’ function. The requirements for both are exactly the same, the API key and event id. But for some reason ‘book_appointment’ doesn’t work. It throws off an error saying:

Error validating cal.com tools.

Looks like the issue has been resolved - I recreated my Cal.com account , tested it an it works. Not sure if that was the issue or if some issue was fixed on the Retell side

We’d love to get your feedback!
