Hi, I have been struggling with connecting Vapi with GoHighLevel. I am trying to build a simple calendar booking agent, but every time during the call, the caller agent says "I am facing difficulties booking the appointment." To connect Vapi with GHL, I copied my Private Integration key from GHL to Vapi's Integration GHL tool. It seemed to connect successfully. However, when I tried to connect Vapi's GHL MCP tool, I followed all the steps, but never got any confirmation message. Has anyone recently connected Vapi with GHL? Please, it would be a big help.
