> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

## Create a condition

1. Open the **Rule Builder** for your campaign.
1. Click **Create Rule**.
1. In **Conditions**, click **Add Condition**.
1. Choose one of the [available conditions](/docs/product/rules/conditions/available-conditions.md).
1. Set the required values.
1. Click **Done**.

The condition is saved. Depending on the condition, you can [add a failure effect](#add-a-failure-effect-to-a-condition)
to it.

:::note
You can also choose **Always Trigger Effects** instead of setting your own conditions. In
this case, the effects will trigger for every update of the customer session.
:::

## Use more than one condition in the same rule

You can create several conditions in a rule. In this case, the Rule Builder evaluates the
conditions in the order in which they appear.

By default, if each condition is `true`, then the effects of the rule are triggered.

You can select if the rule should trigger when at least one condition is true, or if all
of the conditions should be true:

1. In **Conditions**, click **When all of these are true**.
1. Select **All** or **At least one**.

:::tip
You can also group conditions using the **Create a group of conditions** condition.
:::

## Add a failure effect to a condition

Depending on the condition, you can add a failure effect to it. The effect is applied if
the condition is not met during the rule evaluation.

You can use a failure effect to create a custom message that communicates to a customer
what they can do to fulfill the condition and receive the promotion.

Message examples:

- `Spend $250 or more for $25 off your order.`
- `Buy a third item to get 5% off each item in the bundle.`

:::note
