Creating a Named List

A Named List is a reusable list of values that can be used in Decision Engine rules. You create the list first, then add the values you want the list to contain.

Step 1: Open Named Lists

1. Log in to PayControl.
2. Go to the Decision Engine menu.
3. Open Named Lists.

Step 2: Create the Named List

1. Select the option to create a new Named List.
2. Select the client/sub-client from the scopes panel for whom the Named List belongs to.
3. Enter the Name of the Named List.
4. Enter a Description.
5. Save the Named List.

Step 3: Choose a Good Name

Use a simple, lowercase name with hyphens between words.

Good examples:

• blocked-mccs
• restricted-countries
• merchant-blacklist

Avoid:

• spaces
• uppercase letters
• underscores
• special characters

Step 4: Add Values to the Named List

After the Named List has been created:

1. Open the Named List.
2. Choose the option to add an element or value.
3. Enter one value.
4. Save it.
5. Repeat until all required values have been added.

Example for a Named List called blocked-mccs:

• 4829
• 5967
• 7995

Example for a Named List called restricted-countries:

• Iso3166CountryCode.RUS
• Iso3166CountryCode.IRN
• Iso3166CountryCode.PRK

Example for a Named List called merchant-blacklist:

• Fraud Store Ltd
• Suspicious Merchant
• Test Merchant 01

Step 5: Review the List

Before finishing, check:

• the name is correct
• the description is clear
• all required values have been added
• there are no duplicates or typing mistakes

The Named List is then ready to be used in Decision Engine rules.
