Call and Qualify Meta Leads with LeadSync’s VAPI.ai Integration
If you’re running Facebook or Instagram lead ads, you know how important it is to respond to leads quickly. But let’s face it, most businesses aren’t able to call new leads instantly. That’s where LeadSync’s latest integration with VAPI.ai comes in.
With our VAPI.ai integration, you can have an AI agent automatically call new Meta lead ad submissions as soon as they come in. This instant follow-up gives you a huge advantage in qualifying leads and keeping them engaged.
In this article, we’ll explain what VAPI is, why instant lead follow-up is so powerful, and how to add Vapi to your LeadSync account.
What is VAPI.ai?
VAPI.ai is an AI-powered voice platform that automates both outbound and inbound calls for leads and customers. By using advanced AI voice technology, VAPI agents can:
- Instantly call new leads.
- Answer inbound calls and provide scripted responses.
- Ask qualifying questions based on your scripts.
- Confirm or schedule appointments.
- Transfer calls to a human representative if needed.
It’s like having a virtual sales assistant on standby 24/7, ready to engage with leads or customers as soon as they reach out—whether that’s from an outbound call or an inbound inquiry.
With LeadSync’s integration, you can connect your Meta lead ad campaigns to VAPI in just a few simple steps. Once set up, your AI agent will automatically call new Facebook and Instagram leads the moment they submit a form, ensuring no opportunity slips through the cracks.
Why Does Instant Follow-Up Matter?
Time is everything when it comes to converting leads. Studies show that responding to leads within the first 5 minutes increases your chances of conversion by up to 900% compared to waiting even an hour.
Here’s why:
- Higher Engagement: Leads are most interested and attentive right after they submit a form. A fast response keeps their attention.
- Competitive Edge: Most businesses take hours—or days—to respond. Calling instantly puts you ahead of competitors.
- Better Qualification: Quick follow-up allows you to identify serious leads before their interest fades.
Using VAPI.ai with LeadSync ensures you never miss the perfect moment to connect with a lead.

- Call the lead immediately.

- Schedule a viewing or pass the lead to an agent.
This ensures you connect with buyers while their interest is fresh.
2. Service-Based Businesses
For businesses like plumbers, electricians, or cleaning services, fast follow-up can mean securing a job over competitors. A VAPI agent can:
- Call leads instantly.
- Confirm the type of service needed and urgency.
- Book an appointment or transfer the call.
This automation helps you lock in customers quickly.
3. Coaching or Consulting Services
Coaches, consultants, and agencies often generate leads for discovery calls or strategy sessions. A VAPI AI agent can:
- Greet new leads.
- Ask qualifying questions (e.g., goals, pain points).
- Schedule a consultation on your calendar.
Instant follow-ups ensure your pipeline stays full and efficient.
4. Automotive Dealerships
When a potential customer submits a lead form for a test drive or vehicle inquiry, speed is critical. With VAPI:
- Leads are called immediately.
- Questions about vehicle preferences or financing can be asked.
- Test drives can be scheduled on the spot.
This proactive approach keeps leads engaged and moving toward a purchase.
