Everything you need to run WhatsApp in production.

Sessions & connection

• Link a number by QR or pairing code, with a live status stream while it connects.
• One number per session; create, label, and delete from the API or dashboard.
• Survives restarts and infrastructure moves without re-pairing, with recovery under 90 seconds.
• Every session exposes its own identity, health, warmup stage, and trust score.

Messaging: 22 types

• One unified send endpoint for text, media, location, contacts, reactions, polls, replies, forwards, edits, revokes, presence, short videos, GIFs, link previews, live location, contact lists, and stories.
• Send to people, groups, and channels through the same call.
• Act on a sent message: star, pin, and send read or played receipts.
• Idempotent by design: safe to retry your own requests, never a duplicate to the recipient.
• Full delivery timeline per message: queued, dispatched, sent, delivered, read.

Campaigns & scheduling

• Bulk send with per-recipient personalization variables.
• Schedule sends for a future time.
• Warmup-aware: campaigns that would exceed a young number's safe cap are refused, not silently queued for days.
• Per-recipient media variation so identical files across a list do not look like a blast.

Chats, contacts, groups & channels

• Read conversations and history; archive, pin, mute, mark unread, and set disappearing timers.
• WhatsApp identity done right: on-WhatsApp checks, LID ↔ phone resolution, block / unblock, presence, and profile reads.
• Full group and community administration: roster, invite links, icons, admin settings, join-request review, linked subgroups.
• Channels and Business labels: create, follow, post, react, and label chats and messages.

Webhooks & events

• Multiple endpoints per tenant and per session.
• Every event HMAC-signed over the raw body, with a timestamp and a delivery id.
• At-least-once delivery, retried on a backoff, then dead-lettered, with event history and one-click redelivery.
• One tenant's slow endpoint never delays anyone else's events.

Warmup, trust & pacing

• Automatic warmup stages raise a new number's limits only as it earns trust.
• A per-number trust score, exposed on the session object.
• Human-like pacing with jittered gaps and typing simulation, never a robotic fixed interval.

Groups, channels & communities

• Create groups and manage them programmatically: add and remove members, promote admins, rotate invite links.
• Publish to channels and newsletters and reach followers straight from your backend.
• React to join, leave and group-update events as they happen, and drive backend workflows from group messages.
• No separate feature charge: groups, communities and channels come with the connected number.

Reliability & security

• Postgres is the source of truth; messages are never lost to a queue flush or a worker crash.
• Strict single-owner sessions prevent the credential corruption that forces re-pairing.
• Multi-device: keep using WhatsApp on your phone and in WhatsApp Web while the API drives the number.
• Per-tenant isolation enforced in code; session credentials are encrypted and unreadable by the API tier.

Team, billing & tooling

• Roles (owner / admin / developer / agent), invitations, and an audit log.
• Per-session subscription tiers, usage metering, trials with hard caps.
• OpenAPI spec, typed SDKs with webhook verification built in, and no-code nodes for n8n, Make and Zapier.
