Basic usage

1. Configure

Add PhoneLink.configure to your AppDelegate or App init. Call this once at launch before any verification calls.

import PhoneLink

PhoneLink.configure("your-client-id")

2. Verify

Call PhoneLink.verify to start the verification flow. The SDK opens a secure browser session where the user enters and verifies their phone number.

PhoneLink.verify { result in
    if let phone = result.phoneNumber, let token = result.token {
        // Send token to your server for validation
        print("Verified: \(phone)")
    } else if let error = result.error {
        print("Error: \(error)")
    }
}

Prefilled phone number

If you already have the user's phone number, skip the number entry screen by passing it directly:

PhoneLink.verify(phoneNumber: "+14155551234") { result in
    if let token = result.token {
        // Send token to your server
    }
}

The user will go straight to the verification code screen.

Server verification

The result.token contains a signed JWT that should be validated on your server before trusting the phone number. The server-side verification is identical across all platforms — see the Server Verification guide.
