Polymorfa vs ZapLigue

ZapLigue is a finished app for WhatsApp call campaigns on your own QR-linked number, with recorded audio, a spoken IVR and an AI voice agent. Polymorfa is an API: your code receives call events, answers calls and handles the audio.

Choose ZapLigue if

  • You want to run call campaigns without writing code.
  • You want a built-in AI voice agent and a visual IVR.
  • A flat R$ 49.90 per number fits your budget.

Choose Polymorfa if

  • You are building calls into your own product and need webhooks and access to the audio.
  • You need SIP to your PBX, or calls on official Cloud API numbers.
  • You need messaging and calls through the same API.
Calls

Three ways to answer.

Answer in a browser with ready-made components, from server code that reads and writes the audio, or on your own PBX over a SIP trunk.

Choose exclusive answering so the first agent takes the call, or shared answering so others can join.

SIP / PBX
Answer in a browser, from server code that reads and writes the audio, or on your own PBX over SIP. The same webhooks follow every call.
Messages and calls

The same number, the same API.

Wavoip sells calls only, so teams pair it with a separate messaging API. Polymorfa sends messages and handles calls on the same number, with the same webhooks and one bill.

Video and group calls run on linked-device numbers. Cloud API calls are one-to-one and audio only.

Both WhatsApp routes arrive through one contract. Moving a number between routes does not mean rewriting your integration.
Pairing

Connect a number without a camera.

QuickLink lets your customer pair with a code typed on the phone instead of scanning a QR code. Wavoip states that pairing without a QR code is not available yet.
