Vercel + Neon integration doesn't seem to complete
When trying to connect my existing Neon account to Vercel, the setup doesn't seem to complete.
Whenever I click on "Configure" from within Vercel's "Integrations" page, it redirects me to a "Add Integration" modal, even though I have already done that.
Also, following this guide https://neon.com/docs/guides/vercel-managed-integration#installation-walkthrough
With my existing Neon account, Neon doesn't appear within "Storage"

And I can't configure the "Preview" enviroment, nor the "resource is required before deployment" checkbox. And that makes all my preview deploys on Vercel fail because there's no
DATABASE_URL and I do a migration within the build command.
I've asked all major LLMs (GPT5, Grok and Claude), and all of them says that DATABASE_URL should be inject automatically by Neon. But either that isn't happening, or the checkbox for awaiting is important and I can't find it.
Also, I can see that the branches are being created on Neon (preview/master and vercel-dev, so it's working somehow.

Hey @Tiago Serafim, there are two ways to connect Neon and Vercel. Neon is on the Vercel Marketplace. That's billed through Vercel. If you use the Storage and Integration tab on Vercel's dashboard, you'll see Neon from the Vercel Marketplace as far as I'm aware. This will promt you to create a managed Neon account - managed by Vercel.
However, there is also Neon's Vercel integration (other way around). If you log into the Neon Console (console.neon.tech) and select an organization (org-wide) or project (project-scope) you should see an Integration's tab/section in the left-side navigation. Select Vercel from there and that should set up your existing Neon account for preview environments with your Vercel app! 🙂
Let me know if that works or if I'm misunderstanding 🙏 happy to help futher!

Hi Andre! Coming from Vercel, it opens a modal and asks if I want to create a new account on Neon or use my existing account, and the flow stays on Vercel. From Neon, the button says "Install from Vercel Marketplace" and it goes to Vercel and the same flow starts asking if I want to create a Neon account or use an existing one. Either way, when managing the integration with my existing account, there's no way to see this screen https://neon.com/_next/image?url=%2Fdocs%2Fguides%2Fvercel_native_deployments_configuration.png&w=1920&q=75&dpl=dpl_DDwLwWov5xAjtXsfLuPYkv91CuTL that is on Neon's docs. And clicking on "Configure" from within Vercel, to configure the integration, prompts me to add Add a new integration. I believe that either Vercel or Neon broke something in flow.
