 | Mappings        | Handle the individual calls to the destination. In them, you define what type of call you want to make to the destination, and what Triggers that call. Individual Destination Actions may come enabled with some predefined mappings to handle common events like Screen calls, Identify calls, and Track calls. Mappings have two components that make this possible: **Triggers** and an **Action**. |

As part of a Trigger, you can use condition-based filters to narrow the scope of the Trigger. <br /> <br /> Self-service users can add a maximum of two conditions per Trigger.                                                                                                                                                             |

 | Actions         | Determine the information sent to the destination. In the Configure action section, you map the fields that come from your source, to fields that the destination expects to find. Fields on the destination side depend on the type of action selected.                                                                                                                                                |
