How can i get taxes on my payment app

Topic summary

A developer is building an offsite payment extension for Shopify and needs to access tax information (name and value) for transactions.

The current issue: Shopify’s offsite payment request only provides the total amount, without breaking down the applied taxes.

Key questions remain unanswered:

  • Whether additional API scopes are required beyond the standard payment scopes
  • Which specific Shopify API should be used to retrieve detailed tax information
  • How to properly access tax breakdowns within the payment flow

The discussion is currently open with no responses or solutions provided yet.
