Securing Your WhatsApp Integration: API Keys, Webhooks, and Data Privacy
Messaging data is sensitive. This checklist covers token handling, webhook verification, and privacy practices for production integrations.
Your WhatsApp integration touches customer conversations, so treat it like any other critical system.
Protect your API tokens
- Store tokens in environment variables or a secrets manager, never in source control.
- Rotate tokens regularly and immediately after any suspected leak.
- Use separate tokens for development and production.
Verify webhooks
Confirm every incoming webhook is genuinely from Whatspie by validating its signature before processing the payload.
Limit what you store
Keep only the data you need, and define a retention period. Delete message content you no longer require.
Use HTTPS everywhere
Webhook endpoints must be served over TLS. Reject plain HTTP traffic.
Audit and monitor
Log API usage and alert on unusual patterns such as sudden volume spikes or requests from unfamiliar IPs.
