Overview

The CSV upload endpoint lets you bootstrap a campaign directly from a spreadsheet. Nexus validates the file, creates a batch, normalises the columns based on the agent’s variable schema, and inserts the calls in a single transaction.

​
Prerequisites

  • Bearer token for the workspace admin who owns the contacts.
  • CSV file containing the columns required by the agent.
  • At least one provisioned phone number to associate with the batch.

​
Request

​
Authorization
string
required
Bearer token for the workspace admin.

CSV/Excel File Requirements:
  • Supported formats: CSV (.csv) or Excel (.xls, .xlsx)
  • Must include a header row
  • Must include phoneNumber column (required)
  • Must include all mandatory variables defined by the agent
  • CSV headers should match agent variable keys (e.g., phoneNumber, name, account_id, custom_field_1)
  • The phoneNumber column is required; all other columns are flexible based on your agent’s needs
  • Extra columns are stored and forwarded to the agent state machine
  • File encoding should be UTF-8
  • Empty files or files with no valid rows will be rejected
File Processing:
  • The system automatically detects file type by extension
  • Excel files use the first sheet
  • Invalid rows are identified and reported (unless type="true")
  • Data is normalized and validated against agent requirements
  • Phone numbers are deduplicated (only the first occurrence is kept)
