Frequently asked questions

Is my data secure?

All data is encrypted in transit and at rest. Webhook payloads are signed so you can verify they came from Nexus.

How quickly does data sync?

Webhooks fire within seconds of registration. API pulls are available immediately.

What if my webhook fails?

Nexus retries failed webhooks 3 times with increasing delays. You can also manually retry from your integration dashboard.
