How it works

Event in. WhatsApp out.

Hook FlareSend into payment gateways, CRMs, and order systems. Send clear transactional messages customers actually open.

Order, shipping, and appointment notifications
Works with any backend that can call HTTP
Optional inbound webhooks for replies
Schedule reminders ahead of time
Designed for African SME workflows

How FlareSend connects: You link your own WhatsApp number by scanning a QR code, then call a simple REST API. Setup is fast and does not require Meta Cloud API business verification. For very large official-template campaigns, Meta’s Cloud API may still be a better fit — see the comparison.

FAQ

Quick answers

Is this only for marketing?

No. Transactional notifications usually convert better and are safer when customers expect them.

Can I personalize messages?

Yes. Build the message string in your app with customer name, order id, amounts, and links.

What about quiet hours?

Use FlareSend scheduling or your own queue to avoid late-night sends.
