- Interactive Feedback: Users can press keys to confirm or reject options instantly.
- Fraud Reduction: Harder for bots to bypass voice-based verification steps automatically.

FAQ
Frequently Asked Questions
Everything you need to know about integrating reliable voice calling into your application architecture.
What is a Voice API?
A Voice API acts as a communication bridge, allowing developers to programmatically launch and listen to voice calls directly from their backend systems using standard webhooks and HTTP commands.
Is Voice OTP more reliable than SMS?
Yes, drastically so. SMS traffic is often subject to aggregator delays, filtering, or network outages. Voice calls are prioritized by telecom networks and provide an immediate, synchronous notification directly to the user.
Do you support interactive IVR (Input gathering)?
Acore feature of our voice stack is gathering DTMF input. We can playback a prompt, capture the keys the user pressed (e.g. "1 to confirm order"), and immediately send that payload securely to your webhook endpoint to process.
How hard is it to integrate?
Integration is straightforward. If you have experience consuming basic REST APIs like Stripe or Twilio, you'll feel right at home. We support any popular language (Node.js, PHP, Python, Java, etc.).
Can we use this for Order Confirmation and COD verification?
Absolutely. Automated voice calls can contact customers to confirm their orders by asking them to press 1 to confirm or 2 to cancel. This dramatically reduces fake orders and Cash-on-Delivery return logistics costs.
