# Bunker Transactions

## **Prerequisites**

Before setting up and testing a bunker transaction integration other integrations need to be in place.

* [Transfer of voyage related data to the accounting system.](https://api.dataloy.com/user-guides/accounting-integration-api/voyages)
* [Synchronization of business partners between Dataloy VMS and the accounting system.](https://api.dataloy.com/user-guides/accounting-integration-api/business-partners)
* [Exchange rate transfer to Dataloy VMS.](https://api.dataloy.com/user-guides/accounting-integration-api/exchange-rates)

## **Integration Set-Up**

When a bunker transaction is posted in Dataloy VMS, the document status is set to Ready-for-Posting. Set up a scheduled task and use the request under Data Transaction to extract bunker transactions that are ready for posting. When a bunker transaction is transferred to accounting, update the status to Posted.

## **Test Data**

Test data for bunker transactions can be generated in Booking and Operations > Bunkers-FO tab > Bunker Transactions.

## **Data Transaction**

To get bunker transactions that are ready for posting in [Webhooks](https://api.dataloy.com/dataloy-rest-api/webhooks) the following subscription can be created:

```
{
    "eventType":"U",
    "user": the user code to be used in the subscription,
    "objectType":"Document",
    "expression": "dlpObject.getInvoicingStatus() != null && dlpObject.getInvoicingStatus().getStatusTypeCode().equals(\"RFP\") && (dlpObject.getDocumentType().getDocumentType().equals(\"ACC\"))",
    "url":"your webhook url"
}
```

Alternatively a scheduled job can be setup to use the following request:

**Get bunker transactions that are ready for posting to accounting**

| `GET /Document?filter=invoicingStatus.statusTypeCode(EQ)RFP&filter=documentType.documentType(EQ)ACC` |
| ---------------------------------------------------------------------------------------------------- |

### **Post Transaction**

When an invoice is successfully transferred to the accounting system, the document status has to be updated to *Posted* in Dataloy VMS. This is done in a PUT request:

**Update status to posted for a specific invoice**

```
PUT /Document/{key}
  
{
    "invoicingStatus": "POS"
}
```
