Application sources

See the lists APIcenter loads from an application, such as shipping methods and tax classes, and load them again after a change.

Updated November 9, 2026

The Sources tab of an application shows the lists APIcenter loads from that application, such as shipping methods and tax classes. These lists fill the choices in the settings of your flows.

What you see

  • A card per source with its name and the number of items.
  • A table per source with Value, Description and External ID. At most 30 items per source are shown.
  • "Nothing loaded yet." for a source without items.
  • "This application has no sources." when the application does not use them.

Load the sources again

Do this when you added or changed something in the application, for example a new shipping method, and it is missing from the choices in a flow setting.

  1. Click Load from application. Loading starts in the background.
  2. Wait a few minutes.
  3. Click Refresh to see the result.

When loading could not be started, you see a message. Try again later.
