From f58eb790c668e8cc983b793577087b5a81622f58 Mon Sep 17 00:00:00 2001 From: Hardik Zinzuvadiya <25708027+Z4nzu@users.noreply.github.com> Date: Wed, 14 Jan 2026 12:00:43 +0530 Subject: [PATCH] feat: Add OAuth 2.0 Client Credentials support for Shopify integration Adds OAuth 2.0 Client Credentials Grant flow support to Shopify integration, maintaining full backward compatibility with existing Static Token authentication. Starting from **January 1, 2026**, all new Shopify custom apps created via the [Shopify Dev Dashboard](https://shopify.dev/docs/apps/build/dev-dashboard/create-apps-using-dev-dashboard) must use OAuth 2.0 Client Credentials for authentication instead of static access tokens. This PR implements the new authentication method while preserving existing functionality for apps created before this date. - **Shopify Documentation:** - [OAuth 2.0 Client Credentials Grant](https://shopify.dev/docs/apps/build/authentication-authorization/access-tokens/client-credentials-grant) - [Creating Apps Using Dev Dashboard](https://shopify.dev/docs/apps/build/dev-dashboard/create-apps-using-dev-dashboard) - [Access Token Migration Guide](https://shopify.dev/docs/apps/build/authentication-authorization/access-tokens) - **Related Issue:** #[issue-number] (if applicable) 1. **Dual Authentication Support** - Static Token (for apps created before Jan 1, 2026) - OAuth 2.0 Client Credentials (for apps created after Jan 1, 2026) - Seamless switching between authentication methods 2. **Automatic Token Management** - On-demand token generation - Runtime token refresh (no cron jobs) - 5-minute expiry buffer to prevent mid-request failures - Retry logic with exponential backoff 3. **Enhanced UI** - Authentication Method selector - Dynamic field visibility based on selected method - Clear field labels and descriptions **Core Implementation:** - `ecommerce_integrations/shopify/oauth.py` (new) - OAuth token management - `ecommerce_integrations/shopify/doctype/shopify_setting/shopify_setting.py` - Enhanced with OAuth support - `ecommerce_integrations/shopify/doctype/shopify_setting/shopify_setting.json` - Added OAuth fields - `ecommerce_integrations/shopify/connection.py` - Dual auth support **Migration & Documentation:** - `ecommerce_integrations/patches/set_default_shopify_auth_method.py` - Backward compatibility - `ecommerce_integrations/patches.txt` - Patch registration --- ecommerce_integrations/patches.txt | 1 + .../set_default_shopify_auth_method.py | 23 ++ ecommerce_integrations/shopify/connection.py | 58 +++- .../shopify_setting/shopify_setting.json | 56 +++- .../shopify_setting/shopify_setting.py | 147 +++++++++- ecommerce_integrations/shopify/oauth.py | 259 ++++++++++++++++++ 6 files changed, 534 insertions(+), 10 deletions(-) create mode 100644 ecommerce_integrations/patches/set_default_shopify_auth_method.py create mode 100644 ecommerce_integrations/shopify/oauth.py diff --git a/ecommerce_integrations/patches.txt b/ecommerce_integrations/patches.txt index ea16f841a..af76a2c12 100644 --- a/ecommerce_integrations/patches.txt +++ b/ecommerce_integrations/patches.txt @@ -1,2 +1,3 @@ ecommerce_integrations.patches.update_shopify_custom_fields ecommerce_integrations.patches.set_default_amazon_item_fields_map +ecommerce_integrations.patches.set_default_shopify_auth_method diff --git a/ecommerce_integrations/patches/set_default_shopify_auth_method.py b/ecommerce_integrations/patches/set_default_shopify_auth_method.py new file mode 100644 index 000000000..5472bd662 --- /dev/null +++ b/ecommerce_integrations/patches/set_default_shopify_auth_method.py @@ -0,0 +1,23 @@ +import frappe + +from ecommerce_integrations.shopify.constants import SETTING_DOCTYPE + + +def execute(): + """ + Migration patch to set default authentication method for existing Shopify installations. + This ensures backward compatibility when introducing OAuth 2.0 support. + """ + frappe.reload_doc("shopify", "doctype", "shopify_setting") + + if frappe.db.exists("DocType", SETTING_DOCTYPE): + settings = frappe.get_doc(SETTING_DOCTYPE) + + # Set default authentication method to "Static Token" for existing installations + if not settings.authentication_method: + settings.db_set("authentication_method", "Static Token", update_modified=False) + frappe.db.commit() + + frappe.logger().info( + "Shopify Setting: Set default authentication method to 'Static Token' for existing installation" + ) diff --git a/ecommerce_integrations/shopify/connection.py b/ecommerce_integrations/shopify/connection.py index 4a4c7c86d..e66191ed4 100644 --- a/ecommerce_integrations/shopify/connection.py +++ b/ecommerce_integrations/shopify/connection.py @@ -19,7 +19,12 @@ def temp_shopify_session(func): - """Any function that needs to access shopify api needs this decorator.
