Install Step 2: Enable Fast Checkout on SFCC

The cartridge includes the necessary code for Fast buttons to appear and work on the following pages without requiring any changes:

• Simple Product Detail Page (PDP)
• Cart

Configuration

1. Log in to your Commerce Cloud site with your Business Manager credentials.

2. Activate the previously uploaded int_fast_sfra Cartridge to the site by adding it to your storefront's Effective Cartridge Path.

   • Navigate to:
     Administration → Sites → Manage Sites → {site_id} → Settings
   • In the Settings tab, add int_fast_sfra to the Effective Cartridge Path (e.g. int_fast_sfra:app_storefront_base, as Cartridge names must be provided as a colon-separated list)
   • Click "Apply"

3. Import Fast's metadata XML file to enable custom attributes that support Fast payments.

   • Navigate to:
     Administration → Site Development → Import & Export → Manage Import Files

   • Find the system-objecttype-extensions.xml under /metadata/fast-meta-import/meta

     For reference, this is the location of the file in Fast's SFCC Integration GitHub repository.

4. Connect to OCAPI

   • Navigate to:
     Administration → Site Development → Open Commerce API Settings
   • Select Type: Shop
   • Select Context: Global (organization-wide)

   • Paste in the OCAPI configuration file (provided in JSON format) provided to you by Fast

     Be sure to update "client_id":"<<client_id>>" with the Client ID you obtained prior to starting the installation process

5. Open Fast configuration settings

   • Navigate to:
     Merchant Tools → Site Preferences → Custom Preferences.
   • Click on Fast Configs

6. Enter your Fast configuration details

   • Set Instance Type

     During initial testing, set Instance Type to "Sandbox". Instance Type should only be changed to "Production" after Fast has evaluated your Sandbox setup and you are ready to go live with your changes

   • Set FAST JS URL

     Sandbox: "https://js.sandbox.fast.co/fast.js"
     Production: "https://js.fast.co/fast.js"

   • Set Is Fast Enabled option to "Enabled"

     This is a store-level configuration setting that allows you to quickly enable or disable Fast.

   • Set Fast App ID

     Enter the Sandbox App ID (app_id) provided to you previously by Fast

     Fast APP ID

     The Fast App ID (app_id) can be found in the Install section of your Fast Seller Dashboard. You can also retrieve your Sandbox App ID from the Sandbox Seller Dashboard.

     You will not obtain a production app_id until your Sandbox setup has been validated by Fast

   • Set Fast Theme

     ProTip: Select dark theme if your site has a dark/black background.

7. Save Config

8. Implement Custom Code to Display the Fast Checkout Button

   • Add custom code (provided by Fast) to your storefront's Base ISML files

   • To view the current versions of these ISML files, Navigate to:
     Administration → Site Development → Development Setup → {Code Version} → {Cartridge: app_storefront_base} → cartridge templates default
