WhatsApp Business API

WhatsApp Business API platform for support teams

The API has no interface of its own. Resolvenyx gives it one: a shared inbox, templates, tickets, AI agents and reporting on top of your official WhatsApp number.

What a platform adds to the API

The WhatsApp Business API is the official way for a business to message customers at scale, but on its own it is just an endpoint. To use it as a team you need somewhere for agents to reply, a way to manage templates, routing so messages reach the right person, and records of what happened.

Resolvenyx is that layer. You connect your number through the official Meta WhatsApp Business API, invite your team, and work from one inbox. Plans start at £39 a month with a 7-day free trial and no credit card.

Frequently asked questions

Does Resolvenyx use the official WhatsApp Business API?

Yes. Resolvenyx connects to Meta’s official WhatsApp Business API, not unofficial workarounds, and your number stays tied to your own Meta business account.

Do I need to know how to code?

No. Connection is a guided flow and everything else is a no-code interface.

What does the API cost?

There are two parts: Meta’s per-message charges for business-initiated template messages and your platform plan. See WhatsApp Business API pricing explained and Resolvenyx pricing.

Can I keep using the WhatsApp Business app on the same number?

A number moved to the API typically stops working in the regular app, though Meta has been adding options for some numbers. See migrating from the app to the API.

How is the API different from the WhatsApp Business app?

The API supports unlimited agents through a platform, templates, campaigns and automation. See WhatsApp Business API vs app.
