Journey fit

Primary fit

BuildIntegrations & version control

Customer account extensions are app surface integrations built after you commit to Shopify, which fits Build integrations. Extensions hook Shopify’s customer account runtime and APIs—integration work rather than standalone marketing or ops monitoring.
