Rule Engine

General

The Checkout Rule Engine allows you to dynamically control checkout options such as delivery, shipping, and payment methods.

By defining rules, you can automatically enable, disable or hide options. You can also trigger notifications based on customer, order, or payment data.´

Example use cases:

  • Certain delivery options are disabled for large items
  • Disable a shipping option for certain country.
  • Disable payment methods that are prone to fraud for certain basket values/items/shipping addresses.
  • Restrict express payment methods to certain user groups.

Rules

Rules can change how available checkout options behave in three ways:

  • Disable – the option remains visible but cannot be selected
  • Hide – the option is completely removed from the checkout view
  • Notification – a message is displayed when the customer tries to select the option

Supported option categories are

  • Delivery
  • Shipping
  • Payment
  • Collection Points

Creating Rules

Rules are created at the shop level.

To add a rule:

  • In the SCAYLE Panel, open Settings ➜ Rule Engine.
  • Select +ADD RULE or +ADD FIRST RULE.

Complete the 3 sections on the New Rule page.

  1. General Info: Add a Name and Description for the rule.
  2. Click ADD CONDITION to add a new rule:
  • Select an object or collection from the list (e.g., order, customer, payment).
  • Menus are populated based on previous selections (e.g., order > id, customer > lastName, payment > amount).
  • When the variable selection is complete, click ADD.
  • Select the operator (e.g., =, !=, >, <, <=, IS, IS NOT, IN, NOT IN) and corresponding value (e.g., 10, London).
  • To add a sub-condition, click the + SUB CONDITION button.

When adding a sub-condition, you have to choose the same operator for multiple sub-conditions within the rule.

  • Optional Add another rule (condition) with AND/OR operators.
  1. Results: Select one or more results to trigger if the conditions are met (e.g., Payment Options ➜ All Payment Methods ➜ Deactivate Payment Method).
Results

Rule Engine Result.

Rule Engine Result: Deactivate payment method.

Since the rules disable options, it is easier to start with the more general excludes and then become more specific.

  • For example, first, exclude shipping options that are not relevant for one country so you don't have to repeat the exclusion in every rule

Managing rules

To edit a rule:

1. Go to Settings ➜ Rule Engine.

2. On the Rule Engine page, hover over the three-dot menu on the rule you want to edit, and Edit.

To deactivate a rule:

1. Go to Settings ➜ Rule Engine.

2. On the Rule Engine page, hover over the three-dot menu on the rule you want to deactivate, select Deactivate.

To delete a rule:

1. Go to Settings ➜ Rule Engine.

2. On the Rule Engine page, hover over the three-dot menu on the rule you want to delete, and Delete.

Examples

The following examples are intended to explain some real-world scenarios.

Complex scenarios might include conditions and sub-conditons. Within one condition you can only set sub-conditons using the same operator (AND/OR).

Minimum Order Value (MOV) for Payment Method

A rule can be set for payment methods requiring a minimum order value (MOV). For example, you may want to disable the Accounting (B2B) payment method for orders less than a threshold. If MOV is not reached, the payment method is deactivated (does not appear in checkout).

To set this rule:

  1. Add a Name (e.g., "MOV for Accounting") and Description (e.g., "Minimum Order Value for Accounting Payment Method")
  2. Add the Condition: order > cost > withoutServiceCost <= 5000 (≙ 50.00€)
  3. Select the Result: Payment Options > Accounting | Deactivate Payment Method
  4. Click Create to save the rule

Example- Minimum Order Value (MOV) for a Payment Method

Shipping Costs per Country

A rule can be set to enable/disable specific shipping costs for a given shipping country (global or EU shop). For example, you can create a rule where, if a customer selects a shipping country, all shipping options are disabled that do not have a specific cost.

For details on setting Shipping Options (including shipping cost) see Shipping Options.

To set such a rule:

  1. Add a Name (e.g., "Shipping costs for TUR") and Description (e.g., "Disables shipping options for TUR").
  2. Add the Condition: e.g., address > shipping > countryCode IS TUR
  3. Select the Results: e.g.,
  • Shipping Options > rule-engine.available_shipping_options.1299 | Deactivate Shipping Options
  • Shipping Options > rule-engine.available_shipping_options.1546 | Deactivate Shipping Options
  • Shipping Options > rule-engine.available_shipping_options.1427 | Deactivate Shipping Options
  • Deactivate other shipping options where shipping cost ≠ 34,38
  1. Click Create to save the rule.

For conditions with countryCode use the iso_alpha3 (e.g., for Germany it is DEU).

Shipping Options per Shipping Country

Free Shipping Campaign for Time Frame

Rules can be set to enable free shipping for a given time period (e.g., promotion campaign). This requires 2 rules, one to enable free shipping and another to define standard shipping outside of the free shipping time period.

This can be done as follows:

  1. Create a Rule for Free Shipping
  • Add a Name (e.g., "Free Shipping Option") and Description (e.g., "Free shipping for time frame + min. order value").
  • Add the Conditions: e.g.,
    • order > cost > withoutServiceCost >= 4000 (40.00)
    • AND client > currentTime between 06-03-2023 09:00:00 - 09-03-2023 00:00:00
  • Select the Results: e.g., Shipping Options ➜ DHL Standard | Deactivate Shipping Options
  • Click Create to save the rule.

Free Shipping Option

  1. Create a Rule to Disable Free Shipping
  • Add a Name (e.g., "Free Shipping Disable") and Description (e.g., "Enable free shipping only when campaign is active").
  • Add the Conditions: e.g.,
    • client > currentTime before 06-03-2023 09:00:00
    • OR client > currentTime after 09-03-2023 00:00:00
    • OR order > cost > withoutServiceCost <= 4000 (40.00)
  • Select the Results: e.g., Shipping Options > DHL Standard (free shipping) | Deactivate Shipping Options
  • Click Create to save the rule.

Disable Free Shipping Option

Max Order Value

Below is a sample rule set for an order with a max value of 700 €. All payment methods will be deactivated if the customer orders items that cost higher than 700 €.

To set this a rule:

  • Add a Name (e.g., "Max Order Value") and Description (e.g., "Max. order value = 700 €").
  • Add the Condition: e.g., order > cost > withTax > 70000 (≙ 700.00 €)
  • Select the Results: e.g.,
    • Payment Options ➜ All Payment Methods | Deactivate Payment Method
    • Payment Options ➜ All Payment Methods | Error Payment Method
    • Add error message (e.g, "The maximum order value is 700 €")
  • Click Create to save the rule.

Payment methods disabled for order values above 700 €.

Setting Multiple Subconditions: Free Shipping for a time period for chosen customers

Scenario: Set free shipping for all women living in Berlin or Hamburg for orders from the 7th of March until the 9th of March.
You can set a rule containing multiple statements, however within a statement, use the same operator. A single rule can contain multiple subconditions joined by one operator (such as a sub-condition AND another subcondition AND another subcondition), but you cannot mix operators within a single rule. To add a statement with a different operator, create a new rule.

For example, one rule could target:

  • Main condition: is female. AND
    1. Sub condition: shipping after the 7th of March AND
    2. Sub condition: shipping before the 9th of March.

To target women who live in Berlin OR in Hamburg, we have to add a new condition, as we cannot mix operators AND/OR within the same condition statement.

  • Main Condition: lives in Germany.
  1. Sub condition: lives in Berlin OR
  2. Sub condition: lives in Hamburg

To add multiple conditions and sub-conditions:

1. Go to Settings ➜ Rule Engine

2. Select +ADD RULE.

3. Add a Name and Description.

4. Click ADD CONDITION too add a new rule:

  • Select customer > gender > ADD.
  • Choose the IS and select f from the dropdown. Specify the timeframe:
  • Click +SUB CONDITION, then order > createdAt > datetimeOperations > ADD. Select before from the dropdown. Pick the date and time from the calendar.
  • Click ADD CONDITION, then order > updatedAt > datetimeOperations > ADD. Select after from the dropdown. Pick the date and time from the calendar.

Add new condition to specify location. Multiple locations possible using OR operator:

  • Click ADD CONDITION too add a new rule:
  • Select address > shipping > city > ADD. Type a city, for example "Berlin".
  • Click +SUB CONDITION, then address > shipping > city > ADD. Type a city, for example "Hamburg".
  • Switch toggle to OR.

Add free shipping:

  • Select the Results: e.g., Shipping Options ➜ DHL Standard | Deactivate Shipping Options
    • Click Create to save the rule.

Data model explanation

You can access a variety of properties to build your custom rules. Rules can be written on the following standardized data structure. Not all information will be available from beginning to end during the ordering process, for example a shipping address will not yet be available for new customers when evaluating rules for the delivery options filter.
