WhatsApp — integrations and differences from Instagram

What it is

ZeroChats works on WhatsApp the same way as on Instagram: the same AI agent, the same sales links, content, follow-ups, funnel, tags and delegations. The lead writes to you and the AI replies within the same 22-hour window limits from Meta.

Two ways to connect WhatsApp

You can choose between two integration methods. Only one is active at a time per number.

Integration	Which number it allows	Meta verification	Recommended for
WhatsApp Cloud API	WhatsApp Business number	Yes, requires Meta Business	Established businesses already on the API
ZeroChats integration	Any number, even a personal one	No Meta verification required	Small businesses, freelancers or quick tests

Both integrations reach the same agent: the product features are identical from there.

New business or the same one

If your Instagram and WhatsApp leads arrive with very different contexts (for example, different ads or different products), we recommend creating a separate business in ZeroChats for WhatsApp. Each business has its own prompt, links and metrics, which prevents the AI from mixing flows.

If the flows are the same, keep a single business and connect both channels: the AI will respond the same way on either.

Ignore list on WhatsApp

Just like on Instagram, you can exclude numbers the AI should not reply to. They’re managed in Business configuration → Ignored Users, adding the number with its country prefix (for example +34612345678). You can add them one by one or in bulk.

Best practices

• 22h window: applies the same as on Instagram. Configure follow-ups within that range.
• If you use the ZeroChats integration with a personal number, consider opening a dedicated channel for the business: keep personal contacts separate from the lead flow.
• Before connecting WhatsApp Cloud API, make sure your Meta Business account is verified.
• Check the business time zone: office hours and follow-ups depend on it.
