Frequently Asked Questions

How long does it take to integrate?
Most developers integrate Zavu in under 30 minutes. We provide SDKs for Python, Node.js, Go, Ruby, and Java, plus a simple REST API. If you're migrating from Twilio, our API is similar so the switch is straightforward.
Do you support 10DLC?
Yes, we fully support 10DLC (10-digit long code) for US messaging. We handle the carrier registration process and provide guidance on campaign approval.
