Automatic custom discount

Shopify Apps

Topic summary

Automatic custom discount based on customer metafields in a Shopify app. An extra API call is triggered when the user clicks “Proceed to checkout” to apply discounts for specific customers and products. The API response indicates the discount is applied, but the Shopify checkout page does not show updated prices.

Key terms:

  • Customer metafields: custom data attached to customer profiles used to determine eligibility/discount rules.
  • API call: a programmatic request to apply pricing changes.
  • Shopify checkout page: the final purchase screen where prices should reflect any discounts.

Current status:

  • Discount application reported as successful by the API.
  • No visible price change in checkout.
  • No code, screenshots, or attachments provided.

Outcome: No resolution yet. The thread is seeking guidance on why an applied discount isn’t visible at checkout (third-party app context). Pending clarification or solutions; discussion remains open.
