Custom Data

Use customData to pass your own lead metadata through SimZ workflows. SimZ preserves your keys without reshaping them.

Example

1
{
2
  "phoneNumber": "+15551234567",
3
  "firstName": "Jane",
4
  "customData": {
5
    "leadId": "LEAD-001",
6
    "campaignTag": "spring-2026",
7
    "crmOwner": "sales-team-a"
8
  }
9
}

Webhook behavior

When available, SimZ includes this data in webhook payloads at lead.customData.
