Upload Contacts CSV

Uploading contacts is a two-step process. First call this endpoint to get a presigned upload URL, then PUT your CSV directly to that URL.

# Step 1: Get upload URL
curl -X POST https://your-IntraCord-instance/api/v1/s3/presigned-upload-url \
  -H "X-API-Key: dg_your_api_key"

# Response:
# { "upload_url": "https://...", "s3_key": "campaigns/..." }

# Step 2: Upload the CSV
curl -X PUT "https://presigned-url..." \
  -H "Content-Type: text/csv" \
  --data-binary @contacts.csv

Use the s3_key from the response as the source_url when creating a campaign.

CSV format

The CSV must include a phone_number column. Any additional columns are passed as initial_context to each call, making them available as template variables in the workflow.
