To get a project ID for your Vercel project, you have a few options:

1. If your project is already deployed on Vercel, you can find the project ID in your Vercel dashboard:

   • Go to your Vercel dashboard
   • Select your project
   • Navigate to Project Settings
   • The project ID will be displayed in the "General" section

2. If you're using the Vercel API, you can retrieve your project ID by making a request to find a project by name 1:

   curl -X GET "https://api.vercel.com/v9/projects/your-project-name" \ -H "Authorization: Bearer YOUR_TOKEN"

3. If you're using the Vercel CLI, you can link your project and then find the ID in the .vercel/project.json file:

   vercel link cat .vercel/project.json
4. For a new project, you'll get a project ID automatically when you deploy it for the first time with Vercel.

If you're working with Supabase and encountering issues with project IDs, make sure you're using the correct Reference ID which looks something like xvljpkujuwroxcuvossw 2.
