Configure a new supply source

Learn how to use the Supply Sources API or Seller Central to add a new supply source.

Prerequisites

To complete this tutorial, you need:

• Authorization from the selling partner for whom you are making calls. For more information, refer to Authorizing Selling Partner API applications.
• The Selling Partner Insights role assigned to your developer profile.
• The Selling Partner Insights role selected in the app registration page for your application.

Prior to using the Supply Sources API, your seller account must have permission to use Multi-Location Inventory (MLI). If your account does not have MLI permissions, you can request access through the Multi-Location Inventory Sign-up Form. You will receive confirmation that your account is ready within 15 business days.

After your account has permissions to use MLI, your default location and any locations you created on templates allowed by Shipping Settings Automation (SSA) will be automatically added as supply sources. If you need to add or update supply sources, you can use the Supply Sources API or navigate to the Locations tab in Seller Central Shipping Settings.

1. Create new or update existing supply sources via the Supply Sources API or Seller Central UI.
2. Provide location-specific inventory via the API.
3. Create or identify existing templates allowed by Shipping Settings Automation (SSA) that include all of your inventory locations that use these shipping settings.
4. Assign the shipping template created or identified in Step 3 to the SKUs you added inventory per location.
5. Set DEFAULT inventory channel to 0.
6. Add the Selling Partner Insights role to your developer profile.
