Test the Complete Install Flow from Your Listing Preview

What is it?

You can now test your app's complete install flow directly from the listing preview in the listing editor before submitting your app listing for review.

 

Why does it matter?

Previously, there was no way to test the install flow from the listing preview, which could lead to install issues that only surfaced after submission. Now you can validate the full end-to-end experience — including OAuth authentication — and catch any problems early, giving your users a smoother install experience from day one.

This update is available for all apps, and is especially useful if you're adopting the new marketplace install flow.

 

How does it work?

  • In your HubSpot account, navigate to Development.
  • In the left sidebar menu, click App Listings.
  • Hover over an app, then click the More dropdown menu and select Edit draft.
  • In the top right, click Preview.
  • Run through the installation process of the app. Run through the installation process of the app, including all steps of the install flow and OAuth authentication.
