Campaigns

A campaign is how you run a workflow against many contacts automatically. Instead of triggering calls one by one via the API, you upload a list of phone numbers and IntraCord dials them for you — respecting scheduling windows, concurrency limits, and retry rules.

How a campaign works

1. Upload a contacts CSV — must have a phone_number column; any extra columns become initial_context for each call
2. Create the campaign — link it to a workflow, set concurrency, time slots, and retry behaviour
3. Start it — IntraCord begins dialing contacts up to your concurrency limit
4. Monitor progress — track processed, completed, failed, and pending counts in real time
5. Pause and resume — stop and restart at any point without losing progress

The contacts CSV

The CSV drives the campaign. Each row is one contact.

phone_number,customer_name,account_id,plan
+14155550100,Jane Smith,acc_001,premium
+14155550101,Bob Jones,acc_002,basic

Columns beyond phone_number are automatically passed as initial_context to each call, making them available as template variables in your agent's prompt — so each call can feel personalised at scale.

Scheduling and concurrency

Concurrency controls how many calls run simultaneously. It's capped by your telephony plan. Set it conservatively to start.

Time slots restrict when IntraCord is allowed to dial — useful for respecting business hours or regulations:

{
  "timezone": "America/New_York",
  "time_slots": [
    { "day": "monday", "start": "09:00", "end": "17:00" },
    { "day": "tuesday", "start": "09:00", "end": "17:00" }
  ]
}

If no time slots are set, IntraCord dials continuously once the campaign is started.

Retry behaviour

IntraCord can automatically retry contacts who didn't answer, were busy, or went to voicemail:

{
  "retry_config": {
    "max_attempts": 3,
    "retry_interval_minutes": 60
  }
}

Circuit breaker

The circuit breaker automatically pauses a campaign when the call failure rate gets too high — protecting against wasted spend and telephony reputation issues caused by a misconfigured agent or a bad contact list.

When enabled, IntraCord monitors the failure rate within a rolling time window. If it exceeds the threshold, the campaign is paused automatically and must be manually resumed after the issue is investigated.

Setting	Default	Description
Failure Threshold (%)	50	Pause when the failure rate within the window exceeds this percentage
Window (seconds)	120	Rolling time window over which the failure rate is calculated
Min Calls in Window	5	Minimum number of calls required before the circuit breaker can trip — prevents false positives on small samples

A campaign paused by the circuit breaker behaves the same as a manually paused campaign — in-flight calls complete normally, and it can be resumed once the underlying issue is resolved.

Campaign lifecycle

Status	Meaning
draft	Created but not started
running	Actively dialing
paused	Stopped; resumes from where it left off
completed	All contacts processed
failed	Encountered a fatal error

You can pause and resume a campaign at any time. In-flight calls complete normally before a pause takes effect.

Results

Each contact's call creates a run record with the full transcript, recording, and gathered context — same as a manually triggered call. Use the Get Campaign Runs endpoint to retrieve them all.
