Governed WhatsApp for growing teams
Link numbers you control with persistent sessions (including QR onboarding and reconnect). Operators work in the signed-in product; developers use authenticated HTTP routes and outbound webhooks on tiers that unlock them. We do not position Chattu as the official WhatsApp Business API.
Plan-checked limits · Starter: dashboard only (no API/webhooks) · Pro+: HTTP API & outbound webhooks · Session-linked WhatsApp
Sales, support, and notifications live on personal devices instead of accountable systems. Scripts break, SLAs slip, and growth adds more lines with no shared limits, billing alignment, or security posture. You still want the channel—without the chaos.
Persistent linked sessions (QR onboarding and reconnect), plans that enforce sends, automation budgets, contacts, webhook eligibility, and API access—operators use the signed-in product; integrations call authenticated endpoints only where tiers allow. Automation (rules within caps, personalization-aware templates, schedules, imports) aligns with those same sessions.
Choose a plan, connect WhatsApp, set up automation—then work in the web app or plug in HTTP tools on the tiers that allow it.
Register, sign in through the browser, and attach a payment method or plan where your signup flow asks for it. Trial is capped and does not open the HTTP API or webhooks.
Create your client entry, scan the QR code when prompted, or restore an existing linked session—so WhatsApp reconnects cleanly after downtime.
Build templates, import contacts where allowed, schedule messages, and set auto-reply rules inside your quotas. HTTPS webhooks to your URLs are optional and only appear on tiers that include them.
Staff use chats, broadcasts, attachments, groups, and logs in the signed-in web experience. Developers call the authenticated HTTP endpoints when your subscription includes API access—both use the same linked WhatsApp session.
Your tier caps messages, linked numbers, automation, contacts, HTTP access, and webhooks—so expectations stay clear. Administrators get oversight and optional summaries; queued text sends are documented for setups where that option is enabled.
QR, templates, and status — laid out the way you’ll actually use them.
Your QR appears right after sign-in — no waiting, no confusion.
Variables, preview, send — your team speaks in one voice.
Connection state stays visible so you’re never guessing.
HTTP tools where plans unlock them, operator automation, and clarity in your dashboard—all grounded in shipped capabilities.
REST send/receive pathways, client/profile style routes, API keys (account vs per-client on supported paths), validation, rate limiting, optional background text sends with job references when your environment enables the queue path.
Auto-reply rules within plan caps, templates with variable personalization, scheduled messages and contact storage within tier ceilings, optional bulk flows behind feature flags.
Signed-in access to settings, chats, messaging, clients, logs, templates, schedules, contacts; billing or subscription views when checkout is connected; API documentation access aligned with Professional-style entitlements; realtime session signals for linked numbers.
Connection status, usage, and plan context your operators see in the dashboard; subscription summaries when billing is on; optional usage digests by email if you enable them.
HTTP integrations use authenticated requests and per-route validation; availability depends on your plan.
Monthly message allowances, linked clients, automation caps, contacts—and where API keys & webhooks unlock.
Listed prices are examples; confirm totals at signup or checkout. Free tier is intentionally restrictive (no outbound quota); Trial excludes API/webhooks.
