# Batch Calls

> Run outbound campaigns from CSV files.

Batch calls let you call many contacts with one configured agent. Upload a CSV with `customer_phone` and any additional variables your agent needs.

## CSV requirements

* Must be a `.csv` file.
* Must include a `customer_phone` column.
* Additional columns become call parameters for each row.
* Phone numbers should be in E.164 format, for example `+919876543210`.

## Lifecycle

1. Upload CSV and campaign name.
2. FormantAI validates the agent and CSV.
3. Each row is converted into an outbound call message.
4. Calls are processed asynchronously.
5. Results appear in Conversations and batch metrics.

Upload campaigns, list batch calls, and fetch metrics.
