Scale your WhatsApp sales. The official way.
With specialized guidance, connect your business number to WhatsApp API in minutes, without losing your conversations.
What is WhatsApp API?
WhatsApp API is Meta’s official connection for businesses that need to communicate at scale. It’s not an app you download, it’s an integration you connect to a platform like Leadsales. Unlike WhatsApp Business App, it lets you send bulk messages using templates that Meta reviews and approves.
Your customers are looking for you. Many don't get a response in time.
Your team grew, your customers did too — but WhatsApp Business stayed the same. While you're managing the chaos in your inbox, your competition is already:
- Closing the leads that went cold in your queue.
- Following up with customers who didn't buy from you.
- Sending bulk messages in one click, while you're still forwarding them one by one.
You can also reach out, reactivate, and follow up at scale using WhatsApp API with Leadsales.
What WhatsApp Business App can't do for you (and WhatsApp API can)
| WhatsApp Business App | WhatsApp API with Leadsales | |
|---|---|---|
| How many contacts can I message at once? | Broadcast lists of up to 256 contacts. One by one. | Campaigns to thousands of contacts from a single platform. |
| Can my team use it? | 1 number, 1 phone (up to 4 linked devices). | Your whole team works from the same number, each with their own access. |
| Can I send whatever I want? | Any message, no review. But if Meta detects spam behavior, you get blocked. | Messages using templates that Meta reviews and approves. We give you the resources and guidance to create them. |
| How do I organize conversations? | Basic labels. No assignment, no pipelines. | CRM with pipelines, agent assignment, and per-contact tracking. |
| Will I get blocked? | If you send bulk commercial messages from the App, the blocking risk is high. There's no way to anticipate it. | Leadsales applies Meta's policies within its platform. You send, while Leadsales guides you. |
| How much does it cost? | No cost. | Monthly investment: platform + cost per conversation. We will help you estimate this in your demo. |
