Question 1

How to connect Lovable to n8n

Accepted Answer

Use the n8n MCP integration to connect 400+ tools and automate workflows. Enable MCP access in n8n, and Lovable can query your workflows. You can build agentic apps combining Lovable with n8n, and use webhook support via Edge Functions to trigger workflows from your Lovable app.

Question 2

[Database] Can I connect multiple Supabase databases to one Lovable project?

Accepted Answer

Lovable supports connecting one Supabase project via the native integration. For multiple databases, you can manually add additional Supabase connections via Edge Functions and API calls in your code. This requires some manual setup beyond the one-click integration.

Question 3

[Database] Help! I'm stuck in the Lovable ecosystem and can't migrate my database

Accepted Answer

Your data is stored in Supabase (PostgreSQL), which is fully portable. Export via Supabase's native tools or pg_dump, then migrate to any PostgreSQL host. Lovable generates code synced to GitHub—export and redeploy to another platform (Vercel, Netlify, custom servers). You're never truly locked in.

Question 4

Can I customize the email templates?

Accepted Answer

Yes, you can customize email templates using React Email or by building custom HTML in your Edge Functions. Lovable auto-generates template components you can modify. Define templates in your Edge Function code, then customize styling, branding, and content. Use variables for dynamic content like confirmation links and user names.

Question 5

Do I need a custom web domain to use an email domain?

Accepted Answer

No, you don't need a custom web domain to use an email domain. Email and web domains are separate. You can have your app on xxx.lovable.app while sending emails from your verified custom domain (e.g., noreply@yourcompany.com). Email domain setup is independent of web domain setup.

Question 6

Do I need an external email provider like SendGrid or Resend?

Accepted Answer

Yes, for production email sending, you need an external email provider like Resend, SendGrid, or Mailgun. Lovable doesn't provide built-in email sending; it integrates with these providers via Supabase Edge Functions. Resend is the recommended choice and has generous free tier limits (3,000 verified emails/month).

Question 7

Emails are not sending

Accepted Answer

Verify Resend API key is correctly configured and hasn't expired. Check that your email domain is verified (SPF, DKIM, DMARC records set). Ensure the 'From' address uses your verified domain. In Lovable, confirm Edge Functions are deployed via the Cloud tab. Check Resend dashboard for API errors or limits. Contact support@lovable.dev if unsure.

Question 8

What are SPF, DKIM, and DMARC, and do I need to configure them?

Accepted Answer

SPF, DKIM, and DMARC are DNS-based authentication protocols that prove you own the domain and authorize email sending. SPF lists authorized senders; DKIM signs emails cryptographically; DMARC defines domain policy. All three are required for best deliverability. Resend provides the exact records to add to your DNS provider.

Question 9

What is Resend?

Accepted Answer

Resend is a transactional email service that integrates with Supabase Edge Functions to send emails from your Lovable app. It supports confirmation emails, password resets, notifications, and marketing broadcasts. Resend handles delivery, tracking, and compliance, so you focus on building. It's free to start with a verified domain and supports up to 3,000 contacts.

Question 10

Why are my Resend emails going to spam?

Accepted Answer

Emails may hit spam due to missing SPF, DKIM, or DMARC records. Verify your domain fully in Resend and ensure all DNS records are correctly configured. Use a recognizable sender name and avoid trigger words. Resend includes unsubscribe links automatically for compliance. Monitor sender reputation and test emails to catch issues before sending to users.

Question 11

Can I store sensitive API keys in Lovable?

Accepted Answer

Never hardcode or paste API keys in chat or code—they expose secrets. Instead, store keys securely in Cloud → Secrets. Access them only through Edge Functions, where they're protected. Supabase Edge Functions also support secrets for database credentials.

Question 12

How to get a Lovable API key

Accepted Answer

Lovable API details are not extensively documented in the public reference materials. Check docs.lovable.dev or contact support@lovable.dev for API access and key generation.

Question 13

I lost my API key. What should I do?

Accepted Answer

Contact support@lovable.dev immediately to report your lost API key. They can help you revoke the compromised key and issue a new one. Never share API keys in chat or public spaces. For security, always store keys via Cloud → Secrets or Supabase Edge Function secrets, never hardcoded in your project.

Question 14

Can I connect an existing Shopify store to Lovable?

Accepted Answer

Yes, go to Project Settings → Integrations → Shopify and click Connect. Authenticate with your Shopify account, then claim your store. Lovable syncs your Shopify products, collections, and storefront. You can then customize the storefront UI in Lovable and use Shopify for inventory and orders. Verification may be required—ensure you own the store.

Question 15

I claimed my store, but the verification failed. What should I do?

Accepted Answer

Ensure you're using an admin account on the Shopify store. Verification requires proof of ownership. Retry the verification process, or contact Shopify support if account permissions are blocked. Reconnect Lovable to Shopify in Project Settings and attempt claiming again. If the issue persists, contact support@lovable.dev with your store URL.

Question 16

Why can't I create or update products even though Shopify is connected?

Accepted Answer

Check that you've granted Lovable the required permissions in Shopify (Admin → Apps → Lovable). Ensure your Shopify plan includes API access for custom apps. Verify that the authenticated account has admin permissions in the store. If issues persist, disconnect and reconnect Shopify in Lovable Project Settings. Check Shopify Admin → Logs for errors when attempting to create/update products.

Question 17

How do I add payments to my website?

Accepted Answer

Connect Supabase first, then set up Stripe (create account, configure products, enable test mode). Prompt Lovable: 'Add Stripe checkout.' Store your Stripe Secret Key securely via 'Add API Key'. Lovable generates checkout/portal Edge Functions, database tables with RLS, and UI buttons. Test in preview, deploy via 'Apply', then test in production.

Question 18

Verify Webhook Events in Stripe

Accepted Answer

When integrating Stripe payments, verify that Stripe webhooks are firing correctly. Open your Stripe Dashboard → Developers → Webhooks and check event logs. Ensure the webhook URL matches what you configured in Lovable's Edge Functions. Test webhooks by triggering a test payment in Stripe test mode. If events aren't received, check your endpoint URL and authentication headers.

Question 19

Advanced migration using the Supabase CLI

Accepted Answer

Use the Supabase CLI (`npm install -g supabase`) to pull schema and data from your source project (`supabase db pull`, `supabase db dump`), then push to the target project (`supabase link`, `supabase db push`). This command-line approach is faster and more reliable than manual dashboard migrations, especially for large databases. Full instructions are in Supabase CLI documentation.

Question 20

Can I change my mind after adding Cloud to my project?

Accepted Answer

The reference material does not specify whether you can remove Cloud from a project or revert to Supabase. For details on switching between Cloud and Supabase after setup, contact support@lovable.dev.
