Mechanic is a development and ecommerce automation platform for Shopify. :)
Save time by letting this task keep your variant SKUs up to date, generating them based on your product handle, and the initials of each variant option. Optionally, choose to have the task skip updating variants that already have SKUs. Useful for large catalogs, or for anyone who has a consistent SKU format.
Runs Occurs whenever a product is created and Occurs whenever a product is updated, or whenever a product is ordered, or whenever a variant is added, removed, or updated. Configuration includes skip variants that already have skus and product options to keep unabbreviated.
Save time by letting this task keep your variant SKUs up to date, generating them based on your product handle, and the initials of each variant option. Optionally, choose to have the task skip updating variants that already have SKUs. Useful for large catalogs, or for anyone who has a consistent SKU format.
Please note: This task updates SKUs for all products, whether or not they're configured with options and variants.
This task automatically maintains SKUs for your product variants, by combining these elements and joining them with a dash:
503
, if your product is available at myshop.com/products/stylish-shirt-503
)H
if the option is Heather gray
, or HG
if the option is Heather Gray
)(To use the product option's full value, instead of abbreviating it, add the option name to the "Product options to keep unabbreviated" list.)
To illustrate, a shirt available at myshop.com/products/stylish-shirt-503
, with options for size and color, might have these SKUs auto-generated:
503-M-B
503-XL-H
503-S-R
To update your product handle, so as to control the first portion of generated SKUs, open the product in the Shopify admin, scroll to the bottom of the page, click "Edit website SEO", and update the "URL and handle" field to taste. :)
Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Shopifolks, 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.
(By the way, have you seen our documentation? Have you joined the Slack community?)
