The IllumiChat API lets you manage assistants, conversations, contacts, tickets, and more. All endpoints follow REST conventions and return JSON responses.

Request Format

  • Use Content-Type: application/json for request bodies
  • Include authentication credentials with every request (see Authentication)

Response Format

All successful responses return JSON. The structure depends on the endpoint: 
// Single resource
{
  "id": "abc123",
  "name": "My Assistant",
  "createdAt": "2025-01-15T10:30:00Z"
}
