From account to first message.

Quick start

1. Open the dashboard and select Create account.
2. Enter your name, email, and an 8+ character password.
3. Click Create workspace and give your WhatsApp line a name.
4. Scan the QR displayed in step 2 using WhatsApp → Linked devices → Link a device.
5. When status changes to connected, click Generate API key.
6. Copy the key immediately. It is only displayed once.

Account & dashboard

Your user account is isolated to your own customer workspace. The dashboard shows your plan, expiry time, WhatsApp workspace status, QR linking area, API keys, and a ready-to-copy API example. You can sign out at any time; session cookies are HTTP-only and secure in production.

{
  "name": "Acme Support",
  "email": "you@example.com",
  "password": "a-strong-password"
}

After sign-up, the server creates a customer, assigns the Starter plan, starts a user session, and opens the dashboard.

Connect WhatsApp

In the dashboard, create a workspace such as Support line. Wait for its QR code, then scan it only from a WhatsApp account you own or are authorized to operate. The QR is refreshed while the device is connecting. A linked device appears as connected.

API keys

API keys are scoped to one WhatsApp workspace, stored as hashes, and shown once. If you lose a key, revoke it and create another. If a payment is pending, failed, disputed, refunded, or unverified, the key is locked and no API action runs.

Send a message

Use the key from your dashboard after the workspace is connected.

curl -X POST https://your-domain.example/api/send-message \
  -H "Authorization: Bearer wa_your_key" \
  -H "Content-Type: application/json" \
  -d '{"to":"919876543210","message":"Hello from WasenderCRM"}'
