## Testing

- Open the deploy preview or staging URL for
`/dashboard/integrations/vercel/install` with callback params from a
real Vercel Marketplace install redirect (see _Vercel_ subheading
below).
- Confirm the install screen renders with the selected Supabase account,
organization picker, and primary install CTA.
- Remove required callback params such as `code`, `configurationId`, or
`source` to verify the "Missing Vercel installation details" warning
state.
- Clicking "Install integration" with an expired or reused `code` can
show `Creating Vercel integration failed: Failed to get Vercel access
token`; that is expected for preview UI validation. A full successful
install requires a fresh Vercel-generated code from the install flow.

To reiterate; this won’t work because the code will be invalid. But it
should show that everything is hooked up right for prod.

### Vercel

1. Go to Supabase. Open either org-level or project (settings) level
integrations.
2. Tap "[Install Vercel
Integration](https://vercel.com/integrations/supabase-local)".
3. Follow the install instructions from that Vercel page. This should
open a browser window.
4. Copy the URL of that browser window. Take the params and paste them
instead at the end of the deploy preview URL.

Example of #4:

```txt
