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.
More about WhatsApp API (in Spanish)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.
Reaching new customers without waiting for them to make the first move.
You can also reach out, reactivate, and follow up at scale using WhatsApp API with Leadsales.
| WhatsApp Business App | WhatsApp API on | |
|---|---|---|
| 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 person with their own access. |
| Can I send whatever I want? | Any message, with no review. But if Meta detects spam behavior, it blocks you. | Messages with templates that Meta reviews and approves. We give you the resources and guide you as you create them. |
| How do I organize conversations? | Basic labels. No assignment, no funnels. | A CRM with funnels, assignment by agent and follow-up on each contact. |
| Will I get blocked? | If you send bulk commercial messages from the App, the risk of getting blocked is high. There’s no way to see it coming. | Leadsales applies Meta’s policies on its platform. You send while Leadsales guides you. |
| How much does it cost? | There’s no cost. | Monthly investment: platform + cost per conversation. We’ll help you estimate it in your demo. |
No WhatsApp API provider can unblock numbers. But here we explain the most common causes and how to avoid them.

New accounts start with a limit of 250 conversations per day. This limit increases automatically to 1,000 → 10,000 → 100,000 as you maintain good practices and your account quality stays high.
No. You can keep your current number. There’s a mode called Coexistence that lets you keep using the WhatsApp Business app while operating with the API through Leadsales. Learn how it works here (in Spanish).
