Device ID SDK

Important: User Validation

The device ID is a crucial security measure for your backend:

• Validate users during free trials

• Prevent subscription sharing

• Stop multiple account creation

• Track payment sources

• Monitor login patterns

• Detect unusual behavior

SDK Usage

// Get device ID
window.despia = "get-uuid://"

// Wait a moment for no-code tools
setTimeout(() => {
    const deviceId = uuid
    // Send to your backend with auth token
}, 100)

Common Uses

Free Trial Protection

window.despia = "get-uuid://"

setTimeout(() => {
    const deviceId = uuid
    // Check if device already used trial
    validateNewTrial({
        deviceId: deviceId,
        userId: currentUser.id
    })
}, 100)

Subscription Validation

window.despia = "get-uuid://"

setTimeout(() => {
    const deviceId = uuid
    // Verify subscription not shared
    validateSubscription({
        deviceId: deviceId,
        subscriptionId: subId
    })
}, 100)

Login Monitoring

window.despia = "get-uuid://"

setTimeout(() => {
    const deviceId = uuid
    // Track login devices
    validateLogin({
        deviceId: deviceId,
        userId: userId
    })
}, 100)

Backend Implementation Tips

• Store device ID with user accounts

• Link device ID to subscriptions

• Track device ID history

• Monitor multiple accounts per device

• Check device ID on sensitive actions

• Flag suspicious patterns

• Implement trial limitations

• Validate payment sources

Important for No-Code Tools

Tools like WeWeb or Toddle need a 100ms delay before reading the UUID value.
