The unofficial messaging API. Built for teams that don’t have a quarter to wait.
The messaging essentials most teams reach for — send, receive, chats, groups and channels — without business verification, template pre-approval or per-message invoices.
Enterprise-level delivery · Flat monthly rate · Unlimited messages
Side by side
WaAPI vs. the official Business API
Both paths get messages out. One of them costs you a quarter of paperwork and a per-conversation bill.

You need a messaging primitive to plug into existing tooling — not a compliance program or a provider onboarding.

FAQ: unofficial, explained
The trust and compliance questions people ask before switching from the official API.
-
No. WaAPI is not affiliated with, endorsed by or sponsored by the messaging platform or its operators.
-
WaAPI is a tool. How you use it is your responsibility — respect opt-outs, obey anti-spam laws, and follow the platform’s Terms of Service. The same principles apply to any messaging integration, official or not.
-
Follow our best-practice guide: respect 15-second send intervals, warm up new numbers slowly, never blast cold lists. Bans overwhelmingly come from spammy patterns — not from using an API.
-
Your code stays mostly the same: send-message, receive-webhook, manage chats. We built WaAPI around the same primitives the official API exposes, so migration is a reconnect, not a rewrite.
-
The same service already powers thousands of active developers in production, with resilient delivery built in.
-
Yes. Outbound webhooks are signed with your secret, retried with exponential backoff, include a request ID for idempotency, and can be filtered per event.
-
Yes. One subscription, many accounts — each exposed as a separate instance with its own webhook, token scope and API surface.
