Understanding campaign evaluation

Understanding how Talon.One executes one or more campaigns is important to help you build advanced promotion use cases.

Evaluating campaigns with promotion rules

Evaluation summary

The general evaluation order of campaigns with promotion rules is as follows:

1. Information is fetched from Catalogs.
2. Campaigns are evaluated one by one according to their evaluation tree.
   1. Inside each campaign, cart item filters are evaluated in their order of appearance in the Campaign Manager.
   2. The rules are evaluated in their order of appearance in the Campaign Manager.
   3. Inside each rule, each condition and effect is also checked and applied in order of appearance.
3. The effects are returned via the Integration API.

Evaluating campaigns with strikethrough rules

Evaluation summary

The general evaluation order of campaigns with strikethrough rules is as follows:

1. Talon.One monitors a specific set of events happening in cart item catalogs, or in campaigns containing strikethrough rules.
2. When such an event is triggered, Talon.One evaluates all active campaigns with strikethrough rules according to their evaluation tree.
3. Talon.One sends a request to the URLs set in your strikethrough pricing notifications.

tip

To learn which events trigger a pricing update, see Strikethrough pricing updates.

Evaluating stores-based campaigns

important

Stores-based campaign evaluation is applicable only if your Application has stores. You can create stores in your Application with the Create store endpoint.

There are two types of stores-based campaign evaluation:

• All stores: Your campaign is evaluated for all the stores that are present in the Application.
• Specific stores: Your campaign is evaluated only for selected stores. Each store is linked to the campaign.

Evaluating all stores-based campaigns

Evaluation summary

The general evaluation order of all stores-based campaigns is as follows:

1. Talon.One receives a customer session with or without store integration IDs.
2. Talon.One checks whether stores are linked to the campaigns in the Application.
3. Talon.One evaluates all the stores-based campaigns in the Application along with the campaigns linked to the store integration IDs passed in the customer session, according to their evaluation tree.

example

Imagine you want to run a campaign offering a discount to customers irrespective of their stores.

When Talon.One receives a customer session containing the store integration ID Store_001, it evaluates all the campaigns with all stores-based evaluation.

Evaluating specific stores-based campaigns

Evaluation summary

The general evaluation order of specific stores-based campaigns is as follows:

1. Talon.One receives a customer session with store integration IDs.
2. Talon.One checks whether stores are linked to the campaigns in the Application.
3. From all the specific stores-based campaigns, Talon.One only evaluates those linked to the store integration IDs passed in the customer session, according to their evaluation tree.

example

Imagine you want to run a campaign to offer a discount to customers of particular stores. These stores have store integration IDs Store_001, Store_007, and Store_010.

When Talon.One receives a customer session containing the store integration ID Store_001, it only evaluates the campaigns linked to the particular store integration ID.

Evaluating cart item filters

To increase performance, the Rule Engine evaluates cart item filters only in the following cases:

• A condition referencing a cart item filter is about to be evaluated or a valid effect referencing a cart item filter is going to be applied.

  note

  Only if the effect type is not discount or update.

  In this case, only the cart item filter referenced by the condition or effect is evaluated.

• A discount effect or an update effect is about to be evaluated.

  In this case, the Rule Engine evaluates from top to bottom all cart item filters that haven't yet been evaluated.

Evaluating rules

The campaign rules are evaluated by the Rule Engine from top to bottom as they appear in the Rule Builder section.

important

Before evaluating the campaign rules, the Rule Engine collects any customer profile data using the profile's integration ID, as that data may be required to evaluate the rules.

All conditions of a rule are evaluated and all its effects are applied before evaluating the next rule. If a condition is not met, the rule fails, and the next rule is evaluated.

If all the rules of a campaign fail, the next campaign in the campaign evaluation tree is evaluated.

Evaluating conditions

The conditions of each rule are evaluated by the Rule Engine from top to bottom as they appear in the rule.

All the conditions of the same rule are evaluated before the rule effects are evaluated.

note

If a failure effect was added to a condition or to a group of conditions, the effect is applied as soon as the condition fails.

Evaluating effects

The Rule Engine evaluates whether the effects of each rule can be applied. It does it based on the order in which the effects appear in the rule, from top to bottom.

Each valid effect is added to the array of effects of the customer session response as the Rule Engines evaluates if it can be applied, so the Rule Engine takes the effect into account when evaluating if the following effects can be applied. If one effect cannot be applied, all the other effects in the same rule will also not be applied.

note

Any existing campaign budgets are checked when evaluating if the effects that impact them can be applied.

Example

For this example, consider a campaign with three cart item filters and two rules. The first rule has two conditions and one effect, and the second rule has one condition and two effects.

Cart item filters	Rule 1	Rule 2
Filter 1 Filter 2 Filter 3	Condition 1 Condition 2 Effect 1	Condition 1 Effect 1 Effect 2

Also consider the following:

• Filter 2 is referenced by Condition 2 in Rule 1.
• Filter 3 is referenced by Effect 2 in Rule 2.
• Effect 1 in Rule 2 is a discount effect. The other effects are coupon effects.

The Rule Engine evaluates the cart item filters and conditions, and applies the effects, in the following order:

1. Rule 1
   1. Condition 1
   2. Filter 2
   3. Condition 2
      note

      Filter 2 is evaluated when the condition that references it is about to be evaluated.

   4. Effect 1
2. Rule 2
   1. Condition 1
   2. Filter 1
   3. Filter 3
   4. Effect 1
      note

      Filter 1 and Filter 3 are evaluated when the Rule Engine is about to evaluate whether the discount effect can be applied.

   5. Effect 2
