Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Gurus, everybody.

That’s why we make it easy to configure automation without code, why we make it easy to tweak the underlying code once tasks are installed, and why we publish it all here for everyone to learn from.

  This is an example! It calculates whether or not the order number
  is even, and tags the order accordingly.

{% assign mod = order.number | modulo: 2 %}

{% if mod == 0 %}

  odd
{% endif %}
