WhatsApp in your own systems
Order updates, reminders, OTPs and bulk sends from your website, shop or software, on WhatsApp's official Cloud API.
The API, webhooks and the WooCommerce plugin need a plan with API access. Compare plans

- Send templates, text, images and documents
- Bulk sends: one template to 1,000 numbers per request, each with its own values (amounts, dates, order numbers)
- Contacts, tags and consent; deals in your sales pipeline; campaigns
- API keys that only do what you allow, rate limits per key, and Idempotency-Key so retries never send twice
Webhooks
- Get a request when a customer writes, a message is delivered or read, a template is approved, a deal is won…
- Every request is signed (HMAC-SHA256), retried for a day when your server is down, and logged so you can send it again
- Workflows can call your systems too, signed the same way
WooCommerce
- Order confirmations, payment, shipping and cancellation updates on WhatsApp
- A WhatsApp alert to your team for every new order
- A “Send me order updates on WhatsApp” box at checkout; customers who tick it become subscribed contacts
