Official Meta API, managed infrastructure, first message in under 5 minutes. For devs who build products, not servers.
No credit card. No 14-day trial. One connection free forever.
Unofficial APIs like Evolution and Z-API use WhatsApp Web — which Meta bans. Accounts get banned without warning, without appeal. Always at the worst possible time.
Existing official APIs are built for enterprise. Days of onboarding, 3-digit prices, support that responds in weeks. Not built for you.
Self-hosted means you manage servers, updates, reconnections and incidents. You have a product to build — this can't be your responsibility.
One package. Zero config. TypeScript types included.
$ npm install @wapper/sdk One method call. No payload guessing, no token juggling.
const msg = await client.messages.sendText({ to: "+5511999999999", text: "Your order has been confirmed!", }); // msg.status → "queued"
Signature verified automatically. Retry on failure. You never have to think about this.
import { verifyWebhookSignature } from "@wapper/sdk"; const valid = verifyWebhookSignature( body, req.headers["x-wapper-signature"], secret ); // events: "message_status" | "message_received" | "message_failed"
Connection dropped? We reconnect. You never find out.
Webhook failed? We retry 3 times with exponential backoff. Full log in the dashboard.
One product, multiple numbers. Each isolated, each monitored.
Connection quality dropping? You hear about it before your client does.
Create keys with specific permissions. Rotate without downtime.
Status for every connection, message volume, errors — all on the first screen. Nothing to click.
No credit card. No manual approval. No sales call. Create an account and go.
