# Conditions and operators

Conditions are a way that attributes can be used to shape the flow of the conversation. These conditions are essentially asking a question. If the answer to that question is yes, then the message is eligible for use in the conversation. The various questions being asked are called Operations. 

## Available operations on individual conditions

## Operators to combine multiple conditions

You can chain or group multiple conditions (two or more) together and apply them to any Conversation Object or Message Template, enabling validation through an operator. Currently, the supported operators for chaining conditions are **And** and **Or**.

By default, the operator for multiple conditions is set to **And**.

#### **Example**

Let’s consider an example with two conditions for a Conversation Object: `user_name` and `user_email`.

* **And Operator**: If the operator is set to **And**, the chained conditions will be true only when *both* conditions are met. For instance, the object will be considered valid only if both `user_name` and `user_email` are set.

* **Or Operator**: When the operator is set to **Or**, the chained condition will be true if *either* of the conditions is met. In this case, the object will be valid if either `user_name` or `user_email` is set.

The above also applies to Message Templates.<br>

{% hint style="info" %}
When adding more than two conditions, you will be asked to select an operator.  This operator will apply to all set conditions.  So, if you create 3 conditions, the AND  or OR operator will apply to all 3.
