# Custom CSV Feed

A CSV file where each line contains data for a single item.

It is expected that:

* The IDs of the items are contained in the first column
* The first row of the CSV file is a header (contains names of the columns)

The file is automatically analyzed to determine the used delimiter and quoting.

## How to Set Up

1. Set the URL of your CSV feed.
2. The feed gets processed and a list of properties (columns) that were recognized in the feed is presented in the Suggested properties section. You can pick from this list the properties that you want to synchronize to Recombee. You need to set the correct data type for each of the properties.  
You can also create a custom new property and set the column name for it. This is needed especially in the case of large _.zip_ feeds which cannot be fully processed in this step to obtain the suggested properties.
3. Continue to _Preview_ and check that you are getting expected data for all the properties. When you are satisfied, confirm the settings and the feed will get scheduled for processing.
