Unable to install an unverified app

Develop, Build & Integrate Marketplace Apps
1

Hi,

I’m developing my custom app under Marketplace (Public) Distribution, but I’m unable to install it. On the app installation page, the confirmation input field is disabled, so I cannot enter the required text and proceed with the installation.

Could you please help me identify what might be causing this issue?

Hi @Marklin and welcome, we are so glad to have you here! :hugs:

Thanks for sharing the screenshot and details with the HubSpot Community!

I can confirm that the fact that the input field is disabled is not the expected behavior here.

Can you please confirm that you are a Super Admin or have HubSpot Marketplace Access permissions? This is the requirement as indicated here: " Working with OAuth - HubSpot docs ".

If the permissions are correct and the input is still disabled, I’d recommend contacting HubSpot support and sharing this Community topic so that our Support team can investigate this further.

I’d love to check with our Top Experts: Hi @Anton, @evaldas and @Mike_Eastwood do you have additional suggestions to help @Marklin, please? Have you and/or your customers experienced this?

Let us know if you have additional questions in the meantime @Marklin, we are here for you.

Thanks so much and have a wonderful weekend!

Hi, @Marklin this looks like the confirmation modal is stuck in a loading state rather than the field being intentionally locked. Notice the small blue spinner icon just below the “I accept the risk” text box in your screenshot — that usually means the app metadata (created date, install count, redirect domain) is still being fetched in the background, and the input field only unlocks once that call finishes. If it hangs, the field stays disabled indefinitely.

A few things to try:

  • Hard refresh the install page (Ctrl+Shift+R / Cmd+Shift+R) and wait a few seconds before typing.
  • Try it in an incognito/private window or a different browser — ad blockers or privacy extensions sometimes block the metadata request that populates that modal, which leaves the field disabled.
  • Check that your app’s redirect URL and domain are correctly configured in the developer account — if that data fails to resolve, the modal can fail to fully load and never enable the input.
  • If none of that works, it may be a rendering bug on HubSpot’s end with the new “unverified app” confirmation step — worth reporting directly to HubSpot Support with a screen recording (not just a screenshot), since a static image won’t show whether it’s stuck loading or genuinely locked.
