# Using Box Connector For Flat Files
[Box](https://uwmadison.app.box.com/) is a secured storage service offered by UW-Madison that can be used to store documents securely.

This tutorial walks through setting up the Box connector for moving a file from a source folder to a destination folder in Box. 
The below diagram describes the scenario. In this scenario, `employee.csv` CSV file from the source folder is copied 
to a target CSV file called, `employee.csv` inside a target folder. Note that any other type of connection (such as S3, database etc.) can be 
used interchangeably with the Box connector.

**Note that the Box connector only supports `.CSV` (comma-separated values) files.**

## Box Set Up
* Create two [Box](https://uwmadison.app.box.com/) folders, one as `source` folder and the other as the `target` folder.
* `source` folder contains the file `employee.csv`.

![Source folder.](images/source.png)

* `employee.csv` file looks like below. 
```
FN, LN, Address, City, State, Zip
John,Doe,120 jefferson st.,Riverside, NJ, 08075
Jack,McGinnis,220 hobo Av.,Phila, PA,09119
Stephen,Tyler,"7452 Terrace ""At the Plaza"" road",SomeTown,SD, 91234
```
* `target` folder contains the file `employee.csv`. It just contains the header row. The Synchronization task will
populate the `employee.csv` file from source folder.
 
![!Target folder.](images/target.png)

* Content looks like below (only contains the header of the CSV).
```
FN, LN, Address, City, State, Zip
```
* `employee.csv` in target folder contains only header so that IICS can map source file header to target file header.

## IICS Set Up
### Box Source Connector
* Login to IICS.
* Choose Administrator in the top menu dropdown.
* Choose Connections in the left menu.
* Click on the New Connection button towards the top right of the window. This connection will fetch the `employee.csv` file 
from `source` folder (see scenario diagram).

![!Add new connection.](images/connections.png)

* Select `Box` connector type for a Box connection. Fill `Connection Details`. 
* For `OAuth Access Token:` click the `Get Token` button, and a pop will be appeared for you to authenticate with Box.
* For `URI Request Parameters:` provide `query=employee.csv`. This helps Box connector to narrow down the search for given file. 
See reference at the end for more details.
* Inside Box select `employee.csv` file in each of `source` and `target` folder to get `Box File ID` value.
* After configuring a connection, save it and then click on the Test Connection button to verify that your connection works.

### Box Target Connector
* Repeat above steps and add a second `Box` connection. This connection will update the `employee.csv` file in `target`
folder (see scenario diagram).
* As noted before this also can be a replaced by any other type of connection (e.g. database, AWS S3 etc).

### Synchronization Task
* Create a Synchronization Task in Data Integration. Provide a name and select `insert` as the task operation.

* Provide source information. Select source connection that was defined previously. Select `Single` as the source type. 
Select `employee` as the `Source Object`.

* Provide target information. Select target connection that was defined previously. Select `employee` as  `Target Object`.

![!Synchronization task target.](images/syn-task-3.png)   

* Keep the default values for `Data Filters`.

* Keep the default values for `Field Mappings`.

* Keep the default values for `Schedule`.

* Use the `Run` button to execute the Synchronization Task.

After successfully executing the task, `employee.csv` file inside `target` folder will contain the content from `employee.csv` file from source folder.

## Summary
This tutorial walks through how to set up Box connector to copy content from Box source CSV file to a Box target CSV file.
