Google Calendar + DMHub: Client Scheduling and Reminders via WhatsApp

Most small businesses handle scheduling through a messy mix of phone calls, text messages, and Google Calendar invites. The client calls, you check your calendar, you create an event, you send an invite they may or may not accept. Rescheduling requires another round of back-and-forth.

With DMHub connecting Google Calendar to WhatsApp, the entire scheduling flow happens in one conversation. Clients book, confirm, reschedule, and get reminded — all without leaving WhatsApp.

The WhatsApp Booking Flow

Here's what it looks like from the client's perspective:

Client: "I need to schedule a haircut for this week."

DMHub AI Agent: "I'd be happy to help! Here are the available slots this week:

• Wednesday 2:00 PM
• Wednesday 4:30 PM
• Thursday 10:00 AM
• Thursday 3:00 PM
• Friday 11:00 AM

Which works for you?"

Client: "Thursday at 3 please"

DMHub AI Agent: "You're booked!

Haircut with {{stylist_name}} Thursday, {{date}} at 3:00 PM {{salon_address}}

I'll send you a reminder tomorrow. See you Thursday!"

Behind the scenes, DMHub checks Google Calendar for availability, creates the event, and sets up the reminder sequence. Zero manual work.

Setting Up WhatsApp Booking

Step 1: Define Your Availability

Connect your Google Calendar and configure:

• Business hours: When you accept bookings
• Appointment types: Duration and buffer time for each service
• Booking window: How far in advance clients can book (e.g., 2 weeks)
• Minimum notice: How far in advance they must book (e.g., 2 hours)

Step 2: Enable the AI Booking Agent

DMHub's AI agent reads your Google Calendar in real-time and offers available slots. Configure:

• Which services can be booked via WhatsApp
• Whether the AI should confirm immediately or require staff approval
• Maximum bookings per time slot
• Any scheduling rules (e.g., new clients need longer slots)

Step 3: Set Up the Reminder Sequence

• Booking confirmation: Immediately after booking
• Day before: Reminder with option to reschedule
• Morning of: Final reminder with address/directions
• After appointment: Thank you + rebooking prompt

The Rescheduling Flow

When a client needs to reschedule:

Client: "I need to move my Thursday appointment."

DMHub AI Agent: "No problem! Here are the next available slots:

• Friday 2:00 PM
• Saturday 10:00 AM
• Monday 11:00 AM

Which works better?"

Client: "Saturday morning"

DMHub AI Agent: "Done! Your appointment is now:

Saturday, {{date}} at 10:00 AM {{location}}

Updated reminder will be sent Friday evening."

Google Calendar updates automatically. No manual event editing, no double-bookings.
