Polymorfa vs Baileys

Three reasons teams move from Baileys

1. 01

   An HTTP API instead of a socket in your process

   Polymorfa runs the socket and stores the keys. Your code sends over HTTP and receives events as webhooks signed with HMAC-SHA256, delivered in up to eight attempts over 24 hours, set per webhook.^8,2

   Baileys: Baileys runs a socket in your process. You store credentials, Signal keys and messages yourself, and your store has to keep up with every key change.^9,10

   import makeWASocket, { useMultiFileAuthState } from '@whiskeysockets/baileys'
   
   const { state, saveCreds } = await useMultiFileAuthState('auth_info_baileys')
   const sock = makeWASocket({ auth: state })
   sock.ev.on('creds.update', saveCreds)
   
   await sock.sendMessage('15550001111@s.whatsapp.net', { text: 'Your order shipped.' })

   curl -X POST https://api.polymorfa.com/messaging/support/messages/send \
     -H "Authorization: Bearer $POLYMORFA_API_KEY" \
     -H "Idempotency-Key: order-1042-shipped" \
     -H "Content-Type: application/json" \
     -d '{"conversation":{"phoneNumber":"+15550001111"},"content":{"text":"Your order shipped."}}'

2. 02

   Bring your Baileys sessions

   Polymorfa imports Baileys authentication state through the API. You stop writes to the Baileys state, seal the Signal store snapshot to a key Polymorfa issues and submit it. The number connects without a new QR scan. The feature is in preview.¹

   Baileys: Baileys leaves session storage to you, and version 8 introduces a new session format that needs a one-time migration.^9,11

3. 03

   Calls from code and over SIP

   Polymorfa places and answers calls in a browser, in server code that reads and writes the audio, or on your PBX through a SIP trunk. Linked-device numbers also take video and group calls.^3,6

   Baileys: Baileys detects incoming calls and rejects them. It cannot accept or carry voice or video calls.¹²
