Post-Install Actions & Onboarding

Post-install actions determine what happens immediately after a user installs your Stripe App. A well-designed post-install experience guides users through setup and increases activation rates.

Post-Install Action Types

Stripe supports four post-install action types, each configured in your app manifest:

1. Link to App (Default)

Opens the app in the default drawer viewport. This is the default behavior if no post_install_action is specified:

{
  "post_install_action": {
    "type": "default"
  }
}

The user sees the app’s drawer.default viewport in the Stripe Dashboard sidebar.

2. Link to Onboarding

Opens the app’s dedicated onboarding view, providing a focused setup experience:

{
  "post_install_action": {
    "type": "onboarding"
  }
}

This requires an onboarding viewport declared in your manifest:

{
  "ui_extension": {
    "views": [
      {
        "viewport": "stripe.dashboard.onboarding",
        "component": "OnboardingView"
      }
    ]
  },
  "post_install_action": {
    "type": "onboarding"
  }
}

3. Link to Settings

Opens the app’s settings view, useful when the app requires API keys or configuration before use:

{
  "post_install_action": {
    "type": "settings"
  }
}

This requires a settings viewport:

{
  "ui_extension": {
    "views": [
      {
        "viewport": "stripe.dashboard.settings",
        "component": "SettingsView"
      }
    ]
  },
  "post_install_action": {
    "type": "settings"
  }
}

4. Link to External URL

Redirects the user to an external URL for setup. Use this when your onboarding flow lives outside the Stripe Dashboard:

{
  "post_install_action": {
    "type": "external",
    "url": "https://app.tajo.io/stripe/setup"
  }
}

Caution

External URLs must use HTTPS and should be listed in your allowed_redirect_uris. The Stripe review team will verify that the external URL provides a functional setup experience.

Onboarding Best Practices

Make It Effortless

Minimize the number of steps required to get started:

Pre-fill information available from the Stripe account context
Use sensible defaults for configuration options
Allow skipping optional steps with a clear path to complete them later
Show progress with step indicators for multi-step flows

Make It Customizable

Let users configure the integration to their needs:

Data mapping options, let users choose which Stripe fields sync to Brevo
Sync frequency, offer real-time, hourly, or daily sync options
Selective sync, let users choose which customers or products to sync
Notification preferences, configure alerts for sync errors or important events

Make It Relevant

Show value immediately:

Preview synced data before enabling the integration
Show what will happen when the user completes setup
Provide a test sync option to verify the connection works
Display success metrics after the initial sync completes

OnboardingView Component

The OnboardingView component renders in a focused modal when the user installs the app:

import {
  Box,
  Button,
  Inline,
  Icon,
  Banner,
  TextField,
  Select,
  Divider,
} from '@stripe/ui-extension-sdk/ui';
import type { ExtensionContextValue } from '@stripe/ui-extension-sdk/context';
import { useState } from 'react';

const OnboardingView = ({ environment, userContext }: ExtensionContextValue) => {
  const [step, setStep] = useState(1);
  const [brevoApiKey, setBrevoApiKey] = useState('');
  const [syncMode, setSyncMode] = useState('realtime');
  const [isConnecting, setIsConnecting] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const totalSteps = 3;

  const handleConnect = async () => {
    setIsConnecting(true);
    setError(null);

    try {
      // Store the API key securely
      await storeBrevoApiKey(brevoApiKey);

      // Verify the connection
      const result = await verifyBrevoConnection(brevoApiKey);

      if (result.success) {
        setStep(2);
      } else {
        setError('Unable to connect to Brevo. Please check your API key.');
      }
    } catch (err) {
      setError('Connection failed. Please try again.');
    } finally {
      setIsConnecting(false);
    }
  };

  return (
    <Box css={{ padding: 'large' }}>
      {/* Progress indicator */}
      <Inline css={{ marginBottom: 'large' }}>
        Step {step} of {totalSteps}
      </Inline>

      {error && (
        <Banner type="critical" title="Connection Error">
          {error}
        </Banner>
      )}

      {step === 1 && (
        <Box>
          <Inline css={{ fontWeight: 'bold', fontSize: 'large' }}>
            Connect Your Brevo Account
          </Inline>
          <Inline css={{ marginTop: 'small', color: 'secondary' }}>
            Enter your Brevo API key to start syncing customer data.
          </Inline>

          <TextField
            label="Brevo API Key"
            placeholder="xkeysib-..."
            value={brevoApiKey}
            onChange={(e) => setBrevoApiKey(e.target.value)}
            css={{ marginTop: 'medium' }}
          />

          <Inline css={{ marginTop: 'xsmall', color: 'secondary', fontSize: 'small' }}>
            Find your API key in Brevo under Settings &gt; SMTP &amp; API &gt; API Keys
          </Inline>

          <Button
            type="primary"
            onPress={handleConnect}
            disabled={!brevoApiKey || isConnecting}
            css={{ marginTop: 'medium' }}
          >
            {isConnecting ? 'Connecting...' : 'Connect Brevo'}
          </Button>
        </Box>
      )}

      {step === 2 && (
        <Box>
          <Inline css={{ fontWeight: 'bold', fontSize: 'large' }}>
            Configure Sync Settings
          </Inline>

          <Select
            label="Sync Mode"
            value={syncMode}
            onChange={(value) => setSyncMode(value)}
            css={{ marginTop: 'medium' }}
          >
            <option value="realtime">Real-time (recommended)</option>
            <option value="hourly">Every hour</option>
            <option value="daily">Once per day</option>
          </Select>

          <Divider css={{ marginY: 'medium' }} />

          <Button type="primary" onPress={() => setStep(3)}>
            Continue
          </Button>
          <Button type="secondary" onPress={() => setStep(1)}>
            Back
          </Button>
        </Box>
      )}

      {step === 3 && (
        <Box>
          <Banner type="default" title="Ready to Sync">
            Your Brevo account is connected. Tajo will begin syncing
            customer data automatically.
          </Banner>

          <Box css={{ marginTop: 'medium' }}>
            <Inline css={{ fontWeight: 'bold' }}>What happens next:</Inline>
            <ul>
              <li>Existing Stripe customers will sync to Brevo contacts</li>
              <li>New customers and events will sync in real-time</li>
              <li>View sync status on any customer's detail page</li>
            </ul>
          </Box>

          <Button type="primary" onPress={() => {/* Navigate to dashboard */}}>
            Go to Dashboard
          </Button>
        </Box>
      )}
    </Box>
  );
};

export default OnboardingView;

If your app requires users to sign in to an external account (like Tajo), use a dedicated sign-in view:

import {
  Box,
  Button,
  Inline,
  TextField,
  Banner,
  Link,
} from '@stripe/ui-extension-sdk/ui';
import { useState } from 'react';

const SignInView = ({ onSignInComplete }) => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const [isLoading, setIsLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSignIn = async () => {
    setIsLoading(true);
    setError(null);

    try {
      const response = await fetch('https://api.tajo.io/v1/auth/stripe-app', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ email, password }),
      });

      if (!response.ok) {
        throw new Error('Invalid credentials');
      }

      const { token } = await response.json();

      // Store the auth token securely in Stripe's Secret Store
      await storeAuthToken(token);

      onSignInComplete();
    } catch (err) {
      setError('Sign-in failed. Please check your credentials and try again.');
    } finally {
      setIsLoading(false);
    }
  };

  return (
    <Box css={{ padding: 'large' }}>
      <Inline css={{ fontWeight: 'bold', fontSize: 'large' }}>
        Sign in to Tajo
      </Inline>
      <Inline css={{ marginTop: 'small', color: 'secondary' }}>
        Connect your Tajo account to enable Brevo sync.
      </Inline>

      {error && (
        <Banner type="critical" title="Sign-in Failed">
          {error}
        </Banner>
      )}

      <TextField
        label="Email"
        type="email"
        value={email}
        onChange={(e) => setEmail(e.target.value)}
        css={{ marginTop: 'medium' }}
      />

      <TextField
        label="Password"
        type="password"
        value={password}
        onChange={(e) => setPassword(e.target.value)}
        css={{ marginTop: 'small' }}
      />

      <Button
        type="primary"
        onPress={handleSignIn}
        disabled={!email || !password || isLoading}
        css={{ marginTop: 'medium' }}
      >
        {isLoading ? 'Signing in...' : 'Sign In'}
      </Button>

      <Link href="https://app.tajo.io/signup" external css={{ marginTop: 'small' }}>
        Don't have a Tajo account? Sign up
      </Link>
    </Box>
  );
};

Deep Link Launch with Query Parameters

You can launch specific onboarding steps or pre-fill data using query parameters in deep links:

import type { ExtensionContextValue } from '@stripe/ui-extension-sdk/context';

const OnboardingView = ({ environment }: ExtensionContextValue) => {
  // Access query parameters from the deep link
  const { queryParams } = environment;

  // Pre-fill step from query parameter
  const initialStep = queryParams?.step ? parseInt(queryParams.step) : 1;

  // Pre-fill API key from query parameter (e.g., from Tajo dashboard)
  const prefilledApiKey = queryParams?.brevo_key || '';

  // Source tracking for analytics
  const installSource = queryParams?.source || 'marketplace';

  const [step, setStep] = useState(initialStep);
  const [brevoApiKey, setBrevoApiKey] = useState(prefilledApiKey);

  // ... rest of onboarding logic
};

Generate deep links that pre-fill onboarding data:

// From your Tajo dashboard, generate a link that pre-fills the Brevo API key
const onboardingLink = [
  'https://dashboard.stripe.com/live/acct_xxxxx/dashboard',
  '?apps[com.tajo.brevo-integration][modal]=stripe.dashboard.onboarding',
  '&apps[com.tajo.brevo-integration][queryParams][step]=1',
  '&apps[com.tajo.brevo-integration][queryParams][source]=tajo_dashboard',
].join('');

Handling Returning Users

When a user opens your app after completing onboarding, detect their state and show the appropriate view:

const MainView = ({ environment, userContext }: ExtensionContextValue) => {
  const [authState, setAuthState] = useState<'loading' | 'signed-out' | 'onboarding' | 'ready'>('loading');

  useEffect(() => {
    checkUserState().then((state) => {
      setAuthState(state);
    });
  }, []);

  switch (authState) {
    case 'loading':
      return <Spinner label="Loading..." />;
    case 'signed-out':
      return <SignInView onSignInComplete={() => setAuthState('onboarding')} />;
    case 'onboarding':
      return <OnboardingView onComplete={() => setAuthState('ready')} />;
    case 'ready':
      return <DashboardView />;
  }
};

Tip

Store onboarding completion status in the Stripe Secret Store so you can detect returning users without an external API call.
