External APIs

Build full-stack applications by calling external APIs with environment variables.

You can call external services in your v0 prototypes by storing access keys as environment variables. This works for both third-party and your own APIs.

  1. Make sure your chat is linked to a project
  2. Go to Project Settings → Environment Variables
  3. Click Add Variable and enter your API key (e.g. API_KEY) or authorization token.
Environment variables UI

Then, you can instruct v0 to make calls to your backend APIs and use the API key stored in environment variables to securely connect.

Databases

GitHub

Connect your GitHub repositories to v0 to automatically create projects and track changes.
