官方 API 还是 Chrome 扩展？用 WAWCD，两者兼得。

Yes. The extension has Meta's official WhatsApp Business API fully implemented inside it, alongside WhatsApp Web sending. You can run approved template campaigns through the official API and low-cost web campaigns from the same tool.

No. Installing the extension gives you both sending channels, and you can switch per campaign. The official API is also available as a standalone dashboard at business.wawcd.com if you prefer working outside the browser.

Use the official API when deliverability matters: approved templates, zero blocking risk, verified business messaging, and API access. Use web sending when cost matters most and you accept a higher risk of number restrictions.

For official API messages you pay Meta's standard per-conversation rates, which vary by country and message category. Web sending through the extension has no per-message Meta fee, which is why it is the low-cost channel.

Automating WhatsApp Web carries a real risk of number restrictions — that is why WAWCD is transparent about it and includes the official API in the same extension. For business-critical messaging, we recommend the official API channel.
