# Twingle API: Configuring the Extended Contact Manager extension (XCM)

After the installation of the Twingle API extension, various configuration steps must be carried out so that the connection functions smoothly. Twingle API works only correctly when you  have previously installed the Extended Contact Manager extension (XCM).

Taking over contact data using the Twingle API means that they may produce duplicates in your CiviCRM contact management. Before contacts are added or updated in CiviCRM a data check should take place to avoid this problem. This data check is handled by the Extended Contact Manager extension (XCM). This extension must be configured accordingly for use with Twingle by defining a corresponding profile.

## Creating a Twingle Profile

Your first task regarding the Extended Contact Manager extension (XCM) configuration will be to create a corresponding Twinge profile. This works best if you copy the Default profile.
