Hey guys and gals. I would certainly appreciate any help here. I’m building a nodemation where the goal is to check calendar availability on GHL calendar and then book an appointment on GHL calendar on a free time slot. Problem is, it not working. I’m getting the following error message: HTTP 404 There was an error: “The resource you are requesting could not be found” And when I test it over in the chat, this is the message I’m getting: “It seems there was an issue accessing the calendar to check availability. Unfortunately, I am unable to assist you at the moment.”
Here’s the workflow:
