Data Sources

Data Source identifies the channel through which a transaction is submitted to EFRIS.

The EFRIS platform supports multiple submission channels. However, integrations built using the Kumusoft EFRIS API should typically use 101 (System to System).

Data Source Codes

Code	Description
101	System to System
102	Web Portal
103	Mobile Application
104	Desktop Client
105	Electronic Fiscal Device (EFD)
106	POS System
107	USSD
108	AskURA

Recommended Value

For all integrations using the Kumusoft EFRIS API, the recommended value is:

{
  "dataSource": "101"
}

101 - System to System

Indicates that the transaction was submitted through a direct API integration.

Examples include:

ERP systems

Accounting software

Billing platforms

E-commerce systems

Custom applications

Middleware platforms

This is the value used by most Kumusoft EFRIS API integrations.

Other Data Sources

The following values are defined by EFRIS and may appear in existing EFRIS documentation or legacy implementations:

Code	Description
102	Web Portal
103	Mobile Application
104	Desktop Client
105	Electronic Fiscal Device (EFD)
106	POS System
107	USSD
108	AskURA

Unless specifically instructed otherwise, developers integrating through the Kumusoft EFRIS API should continue to use 101 (System to System).

Invoicing

Credit Notes

Stock Management

Interface Codes

Best Practice: Use 101 for all new integrations unless your implementation requires a different EFRIS-defined channel.
