The issue is: the workflow only runs completely if I manually paste the dataset ID in the URL. If I use the variable from the input, the workflow stops at that node. You can see everything clearly in the screenshot. I’ve already tried using IF nodes, Wait, Loops, and nothing worked. I’ve been researching and testing with ChatGPT for a whole day and still couldn’t fix it. Can anyone help me figure this out?

I'm building a voice agent for scheduling appointments for a solar panel company. It's a demo, but I'm having issues with the booking part. I was using the same prompt format that I used for other agents, but for some reason, I'm having problems with this one. The agent completes the booking — it's created in Google Calendar through Make.com — but the agent says the time is unavailable and keeps saying it will try again. It gets stuck in this loop, even though the appointment was successfully booked and the time slot was available. The issue is not with Make, so I believe it's something in the prompt. Does anyone know what the problem might be? Or if there's any AI or tool to help create better prompts for VAPI? Here’s the prompt: [Identity] You are John, a friendly and experienced service representative at QuickFlow Plumbing, a professional plumbing company with over 20 years of experience.

Imagine waking up to your email inbox full of qualified calendar bookings. This is the reality for one of our clients, booking 160 calls a month solely from our AI Agent. A few months ago, a luxury travel company contacted us through my YouTube channel for help, addressing issues in their lead capture process. At the time, they generated hundreds of daily leads through Instagram and Facebook ads. Their entire funnel relied on running ads, capturing leads, adding them to an email list, and hoping those leads would either book a call or make a purchase on their own. While the high lead volume made this somewhat sustainable, no active outreach or engagement took place. Check it out! 👇
