Create a campaign to organize multiple calls under a single ID. Requires an agent_id that will be used for all calls in this campaign.

Quick Example

curl -X POST https://api.callkaro.ai/call/campaign \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: your_api_key_here" \
  -d '{
    "name": "Sales Campaign Q1",
    "agent_id": "6803fa770b666a64ab1694c1e"
  }'

Workflow

Create the campaign

curl -X POST https://api.callkaro.ai/call/campaign \
  -H "X-API-KEY: your_api_key_here" \
  -d '{
    "name": "Inspection Campaign",
    "agent_id": "6803fa770b666a64ab1694c1e"
  }'

Response:

{
  "batch_id": "68433b7b0dee98e59245ebab",
  "message": "Campaign created successfully",
  "status": "success"
}

Add calls to the campaign

Use the batch_id from step 1 with the outbound call API:

curl -X POST https://api.callkaro.ai/call/outbound \
  -H "X-API-KEY: your_api_key_here" \
  -d '{
    "to_number": "+919876543210",
    "batch_id": "68433b7b0dee98e59245ebab",
    "agent_id": "6803fa770b666a64ab1694c1e",
    "metadata": {
      "name": "Abhinav",
      "city": "Bangalore"
    },
    "schedule_at": "2025-12-31T09:30:00",
    "min_trigger_time": "09:00",
    "max_trigger_time": "18:00",
    "number_of_retries": 3,
    "gap_between_retries": 30
  }'

Monitor in dashboard

Track campaign performance at /dashboard/batch-calls/{batch_id}

When to Use v1

Use Campaign v1 when:

✅ All calls will use the same agent
✅ You have the agent ID ready
✅ You want simpler campaign management

Need flexibility? Use Campaign v2 if you want to use different agents for different calls in the same campaign.

Response

Success (200 OK)

{
  "batch_id": "68433b7b0dee98e59245ebab",
  "message": "Campaign created successfully",
  "status": "success"
}

Save the batch_id - you’ll need it to add calls to this campaign!

Tips

Organize your campaigns: Use descriptive names like “Q1 Sales Outreach” or “December Follow-ups” to easily identify them in the dashboard.

Same agent requirement: All calls added to a v1 campaign must use the same agent_id that was specified when creating the campaign.
