Polymorfa vs Meta Cloud API

Three reasons teams move from Meta Cloud API

1. 01

   Keep your Meta code, add linked-device numbers

   Polymorfa's Graph API accepts Meta's request shape for both Cloud API and linked-device numbers. Change the base URL and token; the body stays the same. An operation a route does not support returns a Meta-shaped capability error.³

   Meta Cloud API: Meta's Cloud API serves official numbers only, with groups capped at 8 participants.²

   curl "https://graph.facebook.com/v23.0/$PHONE_NUMBER_ID/messages" \
     -H "Authorization: Bearer $SYSTEM_USER_ACCESS_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "messaging_product": "whatsapp",
       "to": "15551234567",
       "type": "text",
       "text": { "body": "Your order shipped." }
     }'

   # Same body. Works for a Cloud API or a linked-device number.
   curl "https://api.polymorfa.com/graph/whatsapp/v26.0/$NUMBER_ID/messages" \
     -H "Authorization: Bearer $POLYMORFA_PROJECT_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{
       "messaging_product": "whatsapp",
       "to": "15551234567",
       "type": "text",
       "text": { "body": "Your order shipped." }
     }'

2. 02

   An onboarding page you do not build

   Polymorfa hosts the page. Send a QuickLink and your customer pairs a linked-device number or runs Embedded Signup for a Cloud API number, which is in beta. The Customers API groups numbers and links by customer.^9,10

   Meta Cloud API: Building direct, you pass app review and build the Embedded Signup flow in your own product.¹¹

3. 03

   Calls without running a media stack

   Polymorfa carries the audio. Answer in a browser, in server code that reads and writes PCM audio, or on your PBX through a SIP trunk. Cloud API calls are one-to-one audio; linked-device numbers also take video and group calls.^6,7

   Meta Cloud API: Meta's Calling API hands you signaling, and you carry the audio over WebRTC or SIP. Business-initiated calls are unavailable for business numbers in the US, Canada, Egypt, Vietnam and Nigeria.¹²
