AI Sales Agent
AI Sales Agent
This guide walks through building an AI SDR (Sales Development Representative) that qualifies inbound leads and books demo calls with your sales reps — fully autonomously.
The problem
Your AI agent can research prospects, craft emails, and qualify leads. But when it’s time to book a demo, the workflow breaks. The agent drops a Calendly link, the lead ignores it, and the opportunity goes cold.
With Slotflow, your agent books the demo directly — no links, no friction, no dropped leads.
Architecture
Setup
1. Create your sales reps
Create a human for each sales rep who takes demos:
2. Set availability for each rep
3. Block recurring meetings
Sales reps have team standups and pipeline reviews. Block those times:
4. Register a webhook
Get notified when bookings are confirmed so you can update your CRM:
Agent booking flow
This is the core function your AI agent calls when it’s ready to book a demo:
Handling race conditions
When multiple agents are booking simultaneously, a slot might get taken between your GET /slots call and your POST /bookings call. Slotflow returns 409 SLOT_UNAVAILABLE when this happens.
Build retry logic into your agent:
Webhook handler
When a booking is confirmed, Slotflow POSTs to your webhook URL. Use this to update your CRM:
Multi-rep routing
If you have multiple sales reps, your agent can find the first available one:
Key takeaways
- Use metadata to pass lead context through the booking → your webhook handler can update your CRM with all the context it needs
- Handle 409 errors with retry logic — race conditions are expected in high-volume environments
- Block recurring meetings with schedule overrides so your agent never double-books internal time
- Query slots fresh before each booking attempt to minimize conflicts
