Connections

Create a connection

POST /api/v1/erp/connections

Provider credentials go in the config object; its required keys depend on the provider. Connection targets must be reachable over HTTPS at a public host.

{
  "provider": "sap",
  "name": "SAP Production",
  "config": {
    "base_url": "https://sap.example.com",
    "client": "100",

  "sync_interval_minutes": 60,
  "field_mapping": {
    "work_order_id": "AUFNR",
    "machine_id": "EQUNR"
  }
}

Required config keys by provider:

Provider	Required config keys
sap	base_url, client, username, password
dynamics	base_url, tenant_id, client_id, client_secret
oracle	base_url, username, password

The sync_interval_minutes value governs how often automatic syncs run for the auto_* toggles you enable.

Test a connection

Syncs

Trigger a sync

POST /api/v1/erp/connections/{connection_id}/sync

{
  "direction": "outbound",
  "entity_type": "work_order",
  "entity_id": "WORK_ORDER_UUID"
}

• direction is outbound (push to the ERP) or inbound (pull into Haltless).
• entity_id is optional and targets a single record on an outbound push.

Supported combinations:

Entity type	Outbound	Inbound
work_order	Push work orders	—
production_data	Push production/OEE data	—
downtime	Push downtime records	—
machine	—	Pull asset master data

An unsupported combination returns 400. The response is a list of sync-log entries for the operation.
