I'm experiencing an issue with the native GoHighLevel calendar tools. Despite successfully connecting GHL via OAuth (green checkmark shows in Connections), the tools fail with this error: "GoHighLevelMCPCredential or its authenticationSession not found." What I've tried: - Disconnected and reconnected GHL OAuth multiple times - Selected the correct sub-account/location - Deleted and recreated all 6 native GHL tools (calendar availability check + event create for 2 calendars) - Verified the calendar IDs are correct The OAuth connection shows as active in my dashboard, but the tools cannot find the credential during calls. Details: - Org ID: 4e5cd0e7-bdf6-4903-934a-d8b2948bcfb5 - Assistant ID: 4bb28137-29e0-40fb-b386-06f5d03237ce - Tool types affected: gohighlevel.calendar.availability.check, gohighlevel.calendar.event.create - Calendar IDs: R0z0NkZUbfHO612q5mCO (Alex), qWiXgbcLy8GkKABrTy8a (Ross) Please help me resolve this OAuth credential issue. Thank you!

Hi, Currently there is an ongoing issue related to GHL integration with Vapi, and it will be fixed by end of Q1 this year.

Wow. What’s the work around?

API key GHL integration is also not working? getting same error: GoHighLevelMCPCredential or its authenticationSession not found.

Yes, both GHL integration is having issues. Current workaround is to use GHL's endpoints directly using Vapi apiRequest tool or custom tool and calling GHL endpoints directly (https://marketplace.gohighlevel.com/docs/Authorization/PrivateIntegrationsToken)

This is not good news. If both integrations are having issues, it means we can't add contacts, book appointments, etc. So, is it time to move or close VAPI?

There is a temporary issue with the inbuilt GHL integration. You can still use GHLs endpoints directly to add contacts or book appointments • https://marketplace.gohighlevel.com/docs/ghl/calendars/create-appointment • https://marketplace.gohighlevel.com/docs/ghl/contacts/create-contact

How We can we blindly send a call on specific slot if that is already booked in calender? https://marketplace.gohighlevel.com/docs/ghl/calendars/create-appointment And how does the agent check run time, user time, and available slots?

It wont be possible to use all GHL endpoints directly on tool calls, especially the ones with query parameters. I recommend using n8n as a middleman for such edge cases. It will work best.

So the apiRequest tools still work? Because I tried using the apiRequest tool for finding event, creating event, adding tag, and creating note. None are working.

hey. hey i have got an error in creating workflow using api request node The error is : Save failed Failed to save workflow each value in nodes.tool.server.credentialId must be a UUID This error came if I just use api request node It is not like after a condition or after anything that I do this error is coming, So it is not necessary to ask me again About when this error is exactly coming. And also for the information After creating that node I am filling the details of request url, request http method And request body

@christina, yes the apiRequest tool will work. If you are facing any errors while using apiRequest tool as well, please try it using custom tools, if your issue still persists, please share Call IDs where this issue was occuring. @sai charan, Please create a seperate thread/ticket for posts not related to this issue.
