The Technical Foundation

All these use cases share the same pattern:

Event → Webhook → Processing → Action

Once you understand this pattern, you can:

• Identify client problems
• Design webhook solution
• Implement in hours, not days
• Charge ongoing fees

Getting Started

Pick one use case. Master it. Package it.

Form notifications is the easiest:

• Universal need (every business has forms)
• Obvious value (faster lead response)
• Simple implementation (one webhook)
• Recurring revenue (monthly fee)

Start with ZeroContact for form notifications, then expand to other use cases.

The Agency Advantage

You're not just building websites anymore. You're building automation infrastructure.

Clients don't just need a website. They need:

• Leads to arrive instantly
• Data to flow to the right places
• Teams to be notified of the right things
• Systems to work without manual intervention

Webhooks make all of this possible. And agencies that master webhooks create sticky, recurring revenue.
