Frequently Asked Questions - WhatsApp API
You ask, we answer! Here are the most common questions about our WhatsApp API service.
-
You can get started quickly. After you place your order and your account details are verified, we help you set up WhatsApp Business Platform and connect your number. You’ll receive step-by-step guidance from HetaCloud.
-
In many cases, yes. You can connect a new number or migrate an existing one, depending on its current status. If the number is currently active on the WhatsApp/WhatsApp Business app, it may need to be disconnected or migrated before it can be used with the API. Our team will guide you through the correct process.
-
Yes—this is an official WhatsApp Business Platform solution. To avoid restrictions, you should follow WhatsApp’s policies: collect user consent (opt-in), send relevant content, and stop messaging users who request it. We share best practices to help you maintain a healthy quality rating.
-
Session messages are used when a customer has recently messaged you, allowing free-form replies within the active conversation window. Template messages are pre-approved message formats used to start conversations or send notifications like OTP, order updates, and reminders. We can help you write and submit Templates to improve approval chances.
-
Yes. You can track message status such as Sent, Delivered, and Read. If you integrate with your CRM, you can also display these statuses directly inside your system via webhooks and API events.
-
Absolutely. We provide clear API documentation and webhook examples to receive inbound messages and send replies. If you need a custom integration (CRM, ERP, or internal tools), HetaCloud can guide you to the best approach.
-
Yes. WhatsApp applies messaging limits that depend on your account quality and messaging history. As you maintain good engagement (low blocks/reports, relevant content), your limits can increase over time. We recommend a gradual warm-up plan to keep quality high.
-
Yes. WhatsApp API is ideal for OTP, shipping updates, order confirmations, appointment reminders, and customer support. Most outbound notifications require approved Templates, especially if the customer hasn’t started a chat recently.
-
Pricing typically includes a service plan (depending on your package) plus WhatsApp conversation-based charges, which can vary by country and message type. We’ll help you choose the right plan and estimate your expected costs based on your use case.
-
Yes. You can send images, documents, video, location, and links. You can also use interactive message features such as buttons and list menus to improve customer experience and increase response rates.
