# Front

## Front

### Setup

To get an API Token, in the Front app, navigate to Settings > Plugins & API > API and click the New Token button.

### Modes

#### Upsert Contacts

In this mode, new contacts will be inserted into Front and existing contacts will be updated.

**User Identification**

In order to determine whether a contact should be created or updated, you will need to provide a column mapping that can be associated with a unique [Handle](https://dev.frontapp.com/reference/contacts) in Front.

A user can have multiple handles but we will only use one to determine the existence of a contact in Front. Please provide this mapping in this section of the sync configuration:

**Note:** Please ensure that the column you are mapping to is unique and non-null. Also keep in mind that making changes to this mapping later on can result in unexpected behavior.

#### Update Contacts

In this mode, existing contacts will be updated in Front but new contacts will not be inserted.
