List of strings fields

The custom field type List of strings supports multiple values provided as a comma-separated list.

You can use this to record a custom list of your contacts' interests or preferences.

Example:

If your custom field is "Favourite brands" you can send Ometria a list of brands like this: ["Nike", "Puma", "Reebok"]

Then you can use the customer filter to search for customers who like Nike, or Puma, etc.

Example payload

Finding contacts based on their list of strings

Open the customer filter and search for:

• [List field] > which contains - [preference 1]

E.g.

• Favourite brands > which contains - Reebok

This filter searches for individual strings in an array, e.g. all contacts with the tag 'Reebok', including those with additional preferences like 'Nike'.
