FAQ

Common questions

What is NinzaWP?
NinzaWP is a WhatsApp API Gateway that lets you send and receive WhatsApp messages programmatically via a simple REST API. You link your own WhatsApp number, then use HTTP requests to send notifications, OTPs, reminders, and more.
Do I need a WhatsApp Business account?
No. NinzaWP works with a regular WhatsApp account. You scan a QR code — just like WhatsApp Web — to link your number to your instance.
Is there a free plan?
Yes. The free plan lets you send up to 100 messages per day with 1 instance and full API access. No credit card required.
Which programming languages are supported?
Any language that can make HTTP requests. We have ready-made examples for cURL, Python, JavaScript, PHP, Go, and Ruby. If your language can call a REST API, it works with NinzaWP.
Can I receive incoming messages?
Yes. On Starter and Pro plans you can configure a webhook URL to receive incoming messages and delivery receipts in real time.
What happens if I exceed my daily message limit?
Requests beyond your plan's daily limit will receive a 429 rate-limit error. You can upgrade your plan at any time, and limits reset at midnight UTC.
