Handling Webhook Retries and Idempotency in WhatsApp Integrations

The Webhook Storm

If you blast 100,000 messages, Meta will generate 300,000 webhooks (Sent, Delivered, Read). If your server goes down, 5MinutesAPI will queue these webhooks and retry them. This means you might receive the same payload twice.

Implementing Idempotency

Your database logic must be idempotent. This means processing the same webhook twice should not change the result.

// Example pseudo-code
const processWebhook = async (messageId, status) => {
const exists = await db.query("SELECT id FROM receipts WHERE message_id = ?", [messageId]);

if (exists && exists.status === status) {
return; // Already processed, ignore safely
}

await db.query("UPDATE receipts SET status = ? WHERE message_id = ?", [status, messageId]);
};

By leveraging the unique message_id provided by 5MinutesAPI in every webhook payload, you can ensure your analytics and CRM dashboards remain 100% accurate regardless of network hiccups.
