# Installed Croct from the Vercel Marketplace, what did it actually set up?

Asked by trev on 2025-10-02. Tags: nextjs, vercel, setup.

hey all, I ship a little SaaS on Vercel solo. I clicked through the Croct
integration on the Vercel Marketplace mostly out of curiosity (classic) and
now my project has new environment variables I did not create.

So what did the integration actually configure? And more importantly what do I
still have to do in code before anything personalizes? I have not touched my repo
yet, half expecting magic, half expecting homework

Half magic, half homework, you called it.

The [Croct listing on the Vercel Marketplace](https://vercel.com/marketplace/croct)
is a one-click Next.js integration whose job is the plumbing: it creates the
environment variables on
your Vercel project automatically, which is what you are seeing. That is the
part people usually get wrong by hand, so it is a useful click.

The homework is wiring the SDK in your code. Run:

```croct-cmd
croct init
```

from your repo. It sets up `@croct/plug-next`, the proxy export in
`middleware.ts`, and the provider in your layout. Commit, push, let Vercel
deploy.

To verify the whole chain works, open the Integration page in the Croct
dashboard and look for the green "Received traffic in the past 24 hours" badge
after your deploy gets a few visits. Once that is green you can create your
first slot and start fetching content.

of my integrations honestly. thanks!
