Sending

Start sending messages with the API

Our API enables you to programmatically send WhatsApp messages, facilitating seamless communication with your users. This functionality is ideal for trigger-based events such as appointment confirmations or customer re-engagement notifications.​

Rate limiting

To comply with WhatsApp's API rate limits and ensure reliable message delivery, our system implements the following measures:​

  • Per-Sender Limit: Each individual sender number (e.g., +1234567890) is restricted to sending one message every 10 seconds. This rate limiting helps prevent exceeding WhatsApp's API constraints and maintains optimal delivery performance.​

  • Message Queueing: While you can initiate multiple messages simultaneously, our system queues these messages and dispatches (fifo) them sequentially, adhering to the 10-second interval per sender number. This approach ensures compliance with rate limits while allowing for high-volume messaging.​

Implementing these controls helps prevent exceeding WhatsApp's thresholds, which could result in temporary restrictions or errors.​

Use cases

This API is particularly useful for:​

  • Appointment Confirmations: Automatically notify users of upcoming appointments, reducing no-show rates.​

  • Customer Re-Engagement: Send timely reminders or promotional messages to encourage user interaction and retention.​

By integrating this API into your application, you can enhance communication efficiency and improve user engagement through automated WhatsApp messaging.​
