How to Integrate Lovable with Twilio

Open your Lovable project and navigate to Settings using the gear icon in the top-right corner of the editor. In the Settings panel, select the Connectors section from the left sidebar, then click on Shared connectors. You will see the full list of 17 available connectors. Scroll down to find Twilio in the Communication section and click the toggle to enable it. Lovable will confirm the connector is active with a green indicator next to the Twilio listing. Enabling the shared connector does two things: it tells Lovable's AI agent that your project uses Twilio, so every subsequent chat prompt about messaging will generate Twilio-compatible code; and it registers the connector at the workspace level, making it available across all projects in your workspace without repeating this step. Unlike OAuth-based connectors such as Slack or Linear, Twilio uses API key authentication — there is no OAuth flow to complete here. The next step is where you store the actual credentials.

Click the + icon next to the Preview pane at the top of the Lovable editor to open the Cloud tab. Inside the Cloud tab, click on Secrets in the left panel. This is the secure, encrypted storage area for all API keys — credentials stored here are accessible only from Edge Functions running on the server side, never from your frontend code. Click Add secret and create the following two entries exactly as written (Lovable's AI will reference these names when generating Edge Function code): - Name: TWILIO_ACCOUNT_SID — Value: paste your Account SID from the Twilio Console. It starts with AC followed by 32 characters. - Name: TWILIO_AUTH_TOKEN — Value: paste your Auth Token from the Twilio Console. You can find both values on the main dashboard at console.twilio.com. If you plan to use WhatsApp or want to track which number is sending, also add: - Name: TWILIO_PHONE_NUMBER — Value: your Twilio phone number in E.164 format (e.g., +15551234567) Important: never paste these credentials directly into the Lovable chat window. On Lovable's free plan, chat history can be publicly visible, and keys pasted into chat may be recoverable from Git commit history. Always use the Cloud → Secrets panel. Once saved, secrets appear as masked entries — you can delete and replace them but cannot view the value again.

With the Twilio connector enabled and your secrets stored, you are ready to add messaging to your app. Open the chat panel in the bottom-left corner of the Lovable editor and describe the feature you want. Lovable's AI will read the active Twilio connector configuration, retrieve the correct secret names, and auto-generate a complete Edge Function plus the necessary frontend trigger. The AI generates an Edge Function at supabase/functions/send-sms/index.ts that imports the Twilio SDK for Deno, reads your credentials from Deno.env.get(), and sends a message via the Twilio REST API. It simultaneously creates the React component or form handler on the frontend that calls this Edge Function when a user triggers the action. All of this happens from a single chat prompt — no manual SDK installation, no function scaffolding, no route wiring needed. Below are example prompts for common use cases. Use the one that matches your scenario or adapt the language to fit your app.

Twilio message sending only works in a deployed environment — it will not fire from Lovable's preview iframe because the preview runs in a sandboxed context that does not execute Edge Functions against production Twilio credentials. To test, you need to publish your app first. Click the Publish icon in the top-right corner of the Lovable editor. Review any security warnings (particularly RLS policy alerts), then click Publish or Update if the app was previously published. Lovable will build and deploy your app, including all Edge Functions. The deployment typically takes 30–60 seconds. Once published, open your live app URL and trigger the SMS feature — for example, submit the form or click the button you described in your chat prompt. You should receive the text message on your phone within a few seconds. If the message does not arrive, open the Cloud → Logs tab to view the Edge Function execution log. Look for error messages such as 'Authentication Error' (wrong credentials), 'Invalid phone number' (E.164 format required), or 'Trial account restriction' (Twilio trial accounts can only send to verified numbers — verify your phone number first in the Twilio Console under Verified Caller IDs). For complex messaging setups or if you need to configure Twilio sub-accounts, messaging services, or international number pools, RapidDev's team can help design the right architecture for your use case.

If your app needs to receive inbound SMS or voice calls — for example, a support line, a two-way conversation feature, or a keyword-triggered automation — you will need a Twilio webhook pointing at a Lovable Edge Function. Describe the inbound behavior you want in Lovable's chat and the AI will generate the Edge Function receiver. After Lovable generates the inbound handler Edge Function, you will need to register its URL in the Twilio Console. The Edge Function URL format is: https://[your-project-ref].supabase.co/functions/v1/[function-name]. Find this URL by opening Cloud → Edge Functions in the Lovable editor and copying the endpoint URL for your inbound handler. Then go to the Twilio Console, navigate to Phone Numbers → Manage → Active Numbers, click your phone number, scroll to the Messaging section (or Voice section for calls), and paste the Edge Function URL into the 'A message comes in' webhook field. Select HTTP POST as the method and save. Twilio will now POST to your Edge Function every time someone sends a message to your Twilio number. Your Edge Function can parse the sender's phone number, message body, and any media attachments from the request, then store the data in your Supabase database or trigger further actions.
