How to Integrate Lovable with Plivo

Sign in to console.plivo.com. On the main dashboard (Overview page), your Auth ID and Auth Token are displayed prominently in the 'API credentials' section. The Auth ID looks like a string like MAXXXXXXXXXXXXXXXXXX (starts with MA). The Auth Token is a longer alphanumeric string. Click the 'Copy' icons next to each to copy them. You also need your Plivo phone number — go to 'Phone Numbers' → 'Your Numbers' in the left sidebar and copy the number in E.164 format (+1XXXXXXXXXX for US numbers). This is the src number for outbound messages and calls. For the Messaging API, verify that your number is SMS-capable (shows SMS in the capabilities column on the Your Numbers page). For voice calls, the number must be Voice-capable. If you do not have a number yet, go to 'Phone Numbers' → 'Buy Number' and purchase one with the capabilities you need. Numbers typically cost $0.80-$1.00 per month for US numbers.

Open the Cloud tab in your Lovable editor by clicking the '+' panel selector at the top right. Scroll to the Secrets section and add three secrets by clicking the '+' button for each. Create PLIVO_AUTH_ID and paste your Auth ID (the MA-prefixed string). Create PLIVO_AUTH_TOKEN and paste your Auth Token. Create PLIVO_PHONE_NUMBER and paste your Plivo number in E.164 format (e.g. +12025551234). These secret names must match exactly what your Edge Function uses in Deno.env.get() calls. Plivo uses HTTP Basic Auth where Auth ID is the username and Auth Token is the password — both are required. Lovable's security infrastructure, which is SOC 2 Type II certified, encrypts all secrets at rest and actively prevents hardcoded credentials from appearing in generated code. Never paste your Auth Token into a Lovable chat prompt or code field.

The Plivo SMS Edge Function is one of the simplest CPaaS integrations because the API is clean and well-documented. The endpoint for sending messages is POST https://api.plivo.com/v1/Account/{authId}/Message/ using HTTP Basic Auth with authId as username and authToken as password. The request body is JSON with src (your Plivo number), dst (destination in E.164 format), and text (message content). For multiple recipients, dst can be a comma-separated string. The response is 202 Accepted with a body containing message and message_uuid. Ask Lovable to generate this function. After it deploys, test it from Cloud → Logs by checking that requests are arriving and Plivo is returning 202. Common issues at this stage are wrong Basic Auth encoding or a missing trailing slash in the endpoint URL — Plivo's API requires the trailing slash after /Message/.

Plivo can forward inbound SMS messages and delivery receipts to your Edge Functions. For inbound messages (when someone texts your Plivo number), configure the message URL in your Plivo number settings. For delivery receipts, configure the message status callback URL. Create a second Edge Function called plivo-webhook to receive these callbacks. Plivo sends inbound messages as HTTP POST requests with fields: From, To, Text, and MessageUUID. Delivery receipts contain MessageUUID, Status (delivered, undelivered, etc.), and error codes. Deploy the Edge Function and configure it in Plivo: go to console.plivo.com → Phone Numbers → Your Numbers → click your number → edit 'Message URL' and paste the Edge Function URL, set method to POST. For delivery receipts, the message URL receives both inbound messages and status callbacks based on the payload structure — distinguish them by checking if the Text field is present (inbound message) or only Status and MessageUUID (delivery receipt).
