FAQ

Frequently asked questions

What is Stacko?

Stacko is a WhatsApp marketing and customer-engagement platform built for agencies and growing businesses. You can run broadcast campaigns, work in a shared inbox, build no-code chatbots and automations, and manage many clients from one console.

Is this the official WhatsApp Business Platform?

Yes. Stacko is built on Meta’s WhatsApp Business Platform, and Stacko Ventures LLP has been verified by Meta as a Tech Provider. Messages are sent through the official API, not through unofficial methods.

Can I manage several clients from one account?

Yes. Each client gets its own workspace with its own WhatsApp number, contacts, templates, campaigns, conversations and automations, and you administer them all from a single console. See Stacko for agencies.

How do clients connect their WhatsApp number?

Through Meta’s Embedded Signup. The client signs in with Facebook, chooses or creates their WhatsApp Business Account and number, and Stacko completes the connection. Our team can walk you through it.

Does each client need its own payment method with Meta?

For Tech Provider platforms, Meta requires the business that owns the WhatsApp Business Account to add its own payment method. We guide your clients through this during onboarding.

Can I build chatbots?

Yes. The no-code flow builder lets you design keyword-triggered conversations with questions, branching, delays, tags, human handoff and calls to your own systems. An AI assistant is planned.

How much does it cost?

Request a demo and we will share current pricing for your number of clients and message volume.

How is my customers’ data protected?

Access tokens are encrypted at rest, client data is separated per workspace, roles control who can see what, and important actions are logged. Read our Privacy Policy.

Can you help us get set up?

Yes. We offer onboarding, template setup, flow design and campaign support. See Services.
