Apps And Custom Liquid

Use app blocks first when an app supports Shopify theme app extensions. Use custom liquid only when the app or integration specifically requires code.

App Blocks

  • Install and configure the app in Shopify.
  • Open the relevant template in the theme editor.
  • Add the app block where the customer needs it.
  • Check desktop and mobile layout.
  • Test the app flow, not just whether the block appears.

Custom Liquid

Use Custom liquid or Custom section for small snippets. Avoid large custom layouts when a SAISON section can do the job.

Common Mistakes

  • Pasting app code into multiple sections when one app block would work.
  • Adding custom liquid that changes spacing or breaks mobile layout.
  • Forgetting to test custom code after app updates.
