Clerk API Key

Now we will find the Clerk API Key and add it to our env.ts file:

Configure → API Keys

Clerk API Keys screen

Find “Expo” and copy it.

Copy Expo key

Paste it into env.ts:

export const EXPO_PUBLIC_CLERK_PUBLISHABLE_KEY = [your key here] as const;

Summary of Parts 1‑3

  • Connected our app with Clerk (via API Key)
  • Configured the Redirect URL to forward login results (see Part 2)
  • Ensured the Redirect URL scheme matches the scheme in app.json (see Part 2)

Next: we will configure the Google Cloud Console.
