Unable to save draft in Google Workspace Marketplace SDK Store Listing

Google Workspace Developers Q&A

Hi, I’m configuring the Google Workspace Marketplace SDK for my project in Google Cloud Console.

Path: APIs & Services → Google Workspace Marketplace SDK → Store Listing

When I click “Save draft”, a generic dialog appears:
“We were unable to apply your changes. The operation failed. Please try again.”

There are no validation errors in the form and all required fields are filled in.

What I already tried:

  • Removed all draft testers and left the opt-out URL empty
  • Simplified all support URLs (no #anchors)
  • Saved the “App configuration” tab first, then tried “Store listing” again
  • Closed all Cloud Console tabs and retried in a new session
  • Tried a different browser

Could you please check if there is any backend error or inconsistent state for this project and advise how I can save the Store Listing draft?

Hey,

Hope you’re keeping well.

This issue often happens when the Marketplace SDK listing is in a partially configured or invalid backend state, even if the UI shows no validation errors. First check that your OAuth consent screen is fully published (not in draft) under APIs & Services → OAuth consent screen, and that the app’s scopes match those declared in the SDK configuration. Also confirm your Cloud project has the Google Workspace Marketplace SDK API enabled in APIs & Services → Enabled APIs. If the problem persists, try clearing the listing by removing any uploaded images or localized text, save, then re‑add them.

Thanks and regards,
Taz
