Polymorfa vs NotificaMe Hub

NotificaMe Hub connects the official WhatsApp API alongside Instagram, Messenger, Telegram, marketplaces and more, with reseller subaccounts and BRL pricing. Polymorfa focuses on WhatsApp alone, with linked-device numbers, groups, channels and calls.

Start buildingRead docs

Choose NotificaMe Hub if

  • You need WhatsApp plus Instagram, Messenger, Mercado Livre, OLX and other channels in one place.
  • You resell channels to clients and want subaccounts.
  • You want an n8n node for the whole hub.

Choose Polymorfa if

  • WhatsApp is your product and you need linked-device numbers, groups or channels.
  • You want signed webhooks, an OpenAPI spec and idempotent sends.
  • You need WhatsApp calls from code.
Routes

One contract for both WhatsApp routes.

Z-API and ClickAPI document linked-device numbers. 1MSG, Sent and NotificaMe document the official API. Green API sells both, as separate products with separate docs.

Polymorfa sends and reacts through the same API on both routes, so moving a customer between them does not mean a second integration.

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

Retries that cannot send twice.

Send with an Idempotency-Key and Polymorfa replays the original result for 24 hours instead of sending again. Webhooks carry an HMAC-SHA256 signature and retry up to 8 times over about 41 hours.

Among the APIs here, Sent documents both. Green API authenticates webhooks with a static token header rather than a payload signature.

A retried send returns the first result instead of sending twice. Every webhook carries a signature your server can verify.
Onboarding

Send your customer one link.

QuickLink is a hosted pairing page. Your customer scans a QR code or types a pairing code, and you watch the link move from opened to connected. The Branded QuickLink add-on removes our watermark.

Number health

See trouble before a number goes down.

BanSafe Health scores each production linked-device number from 0 to 100 with versioned rules, and shows the deductions behind the score. A project rule can slow sending, stop the number, log it out, email you or send a webhook when Health drops.

Health is an estimate, not a guarantee. It never reads message content, and no provider can prevent every WhatsApp restriction.

Pricing

Billed for online days.

Per-instance plans charge for a whole month. Polymorfa charges for the days a number is online, so numbers that go offline stop costing money.

Green API and Z-API publish lower monthly prices for a number that is online every day. Compare with your own uptime and volume.

Polymorfa bills a number for the days it is online. Message volume on that number does not change the platform charge. Meta's own fees still apply to Cloud API numbers.

Checked against each vendor's public website and documentation on 24 September 2026. “Not listed” means we did not find the capability on those pages. It does not mean the product lacks it. Prices are list prices shown publicly on that date and exclude Meta's fees and taxes unless stated.
