How can I add 5% of a new order value to a customer's existing loyalty points using Flow?

Hi A_oxolins,

Flow isn’t able to access metafields through the dot-delimited way that the Online Store editor can.

Liquid like this to replace the first line of your Value field may help:

{% assign accumulation = 0 %}
{% for metafields_item in order.customer.metafields %}
  {% if metafields_item.namespace == "loyalty" and metafields_item.key == "points" %}
    {% assign accumulation =  metafields_item.value %}
  {% endif %}
{% endfor %}

Hope that helps!
