Enforcement Export

Introduction

entervo infinite provides ticketless free-flow parking solutions. It supplies information that enables operators to enforce unpaid exit transactions. The enforcement process itself is carried out by a third-party enforcement agency/application. entervo acts solely as an enforcement data supplier. For this purpose, entervo infinite provides a file export interface, which is described in this document. The document contains:

• General information about the interface
• Explanations of the data contained in the exported files

The interface operates in automated mode: all unpaid customer transactions are collected and exported together in a single cyclic (nightly) export.

With each cyclic export, the following files are exported for each car park:

/	Enforcement details	Enforcement images
Enforcement file name	20251110000000_CP9763070_enfo.zip	20251110000000_CP9763070_pict.zip
Naming convention	YYYYMMDDHHMMSS_CARPARKID_Filetype.zip	YYYYMMDDHHMMSS_CARPARKID_Filetype.zip

---

Within the ZIP file the following files are included per car park:

/	Enforcement details	Enforcement images
Enforcement file name	ENFO-CP9763070-20251110000000.xml	c5c500c3-8231-41a2-874d-ca8d86fc479b_77adc2e4-b9e0-33b0-a1bf-94201ff94902_2025-21-10T11-20-12.8Z.jpg c5c500c3-8231-41a2-874d-ca8d86fc479b_545eb93a-537d-3135-bc90-e7bd80b7ca50_2025-09-11T12-34-18.8Z.jpg ...
Naming convention	ENFO-CARPARKID-YYYYMMDDHHMMSS.xml	Sensor ID_BTID_Date/Time stamp

Enforcement File Interface

The export files are transfered via SFTP push from entervo infinite to the 3rd party enforcement agency/ application.

Supported Product Types

The enforcement interface supports the following type of product:

• Short-term parker

Structure of XML

The XML is described in the following chapters. The head of the XML file begins with:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

The whole body is enclosed in:

<parkingTransaction>                      
   <transaction>
      <generalData>
      </generalData>
      <entryData>
      </entryData>
      <paymentData>
      </paymentData>
      <exitData>
      </exitData>
   </transaction>
   <transaction>

      <paymentData>
      </paymentData>
      <exitData>
      </exitData>
    </transaction>
</parkingTransaction>

Every single parking transaction is enclosed in a transaction tag.
