Overview

Creates a batch calling job that will automatically dial contacts from your uploaded list. The job can start immediately or be scheduled for a future time. Key Features:

CSV file upload (up to 10,000 contacts)
Automatic phone number validation (E.164 format)
Scheduled start with timezone support
Configurable retry policy
Two-level concurrency control

Prerequisites

Before creating a batch job:

Register a phone number in Studio → Phone Numbers
Assign an outbound agent to that phone number
Ensure sufficient credits in your organization account
Prepare CSV file with at least a phone column

The agent assigned to the phone number must use Pipeline or Realtime architecture. Text-only agents cannot make voice calls.

Examples

Example 1: Immediate Start (CSV)

curl -X POST "https://api.talkifai.com/batch/create" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@contacts.csv" \
  -F "fromPhoneNumberId=phone_abc123" \
  -F "name=Payment Reminders" \
  -F "concurrentCallLimit=5" \
  -F "maxAttempts=3"

Example 2: Scheduled Start with Timezone

curl -X POST "https://api.talkifai.com/batch/create" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "fromPhoneNumberId": "phone_abc123",
    "name": "Morning Follow-ups",
    "contacts": [
      {"phone": "+12025550101", "name": "John Smith"},
      {"phone": "+12025550102", "name": "Jane Doe"}
    ],
    "scheduledStartTime": "2025-03-01T09:00:00",
    "timezone": "America/New_York",
    "concurrentCallLimit": 3,
    "maxAttempts": 2
  }'

Example 3: Custom Fields for Personalization

curl -X POST "https://api.talkifai.com/batch/create" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "fromPhoneNumberId": "phone_abc123",
    "name": "Renewal Campaign",
    "contacts": [
      {
        "phone": "+12025550101",
        "name": "John Smith",
        "customerName": "John Smith",
        "renewalDate": "Feb 1",
        "planType": "Premium"
      }
    ],
    "concurrentCallLimit": 5
  }'

Then in your Agent System Prompt, use the custom fields:

You are calling {{customerName}} about their {{planType}} plan renewal on {{renewalDate}}.
Greet them by name and confirm the renewal date.

Cost Estimation

The system estimates cost based on:

Number of contacts
Agent architecture (pipeline vs realtime)
Average call duration (assumed 2 minutes)

Example calculation for 100 contacts:

Pipeline agent: ~ $3.50 ($ 0.035/call)
Realtime agent: ~ $7.00 ($ 0.07/call)

Actual costs may vary based on call duration. The estimate assumes 2-minute average calls.

How It Works

1. Upload CSV / Send JSON
         │
         ▼
2. Validate phone numbers (E.164 format)
         │
         ▼
3. Look up fromPhoneNumberId
         ├── Not found → 404 Error
         └── Found → Get org + agent
                   │
                   ▼
4. Check agent architecture
         ├── Text agent → 400 Error
         └── Voice agent → Continue
                   │
                   ▼
5. Validate contacts (remove duplicates)
         │
         ▼
6. Check organization credits
         ├── Insufficient → 400 Error
         └── Sufficient → Continue
                   │
                   ▼
7. Create batch job record
         │
         ├── Scheduled? → Store in Redis defer queue
         └── Immediate? → Enqueue contacts to worker queue
                   │
                   ▼
8. Return batch job ID
