Verify Inbound Callers Automatically via Webhooks
When your phone system sends a webhook about an incoming call, Notis instantly verifies the caller's phone reputation.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Phone Number Information
Tool to retrieve detailed information about a specific phone number, including reputation, business and carrier details, and ftc complaints. use when the number is in e.164 format and set hlr=true to include hlr data (adds 1-3 seconds to response).
Why this helps
External phone systems send webhooks about incoming calls but you don't verify caller legitimacy before answering
- Screen callers before answering
- Verify inbound call legitimacy
- Integrate phone verification into call flow
- Reduce spam calls
Setup
Build it in a few focused steps.
- 1Connect Callerapi to Notis and configure a webhook trigger in your phone system
- 2In Notis, tell your phone system: 'When an incoming call webhook arrives with a phone number, get phone number reputation from Callerapi'
- 3Select 'Webhook' as your trigger type and route caller verification data to your call-handling channel
- 4Test by sending a test webhook from your phone system and confirming caller reputation data appears
- 5Incoming calls will now be pre-screened with phone reputation data before your team answers
Questions about this workflow
How do I connect my phone system to Notis?
Notis provides a webhook URL. Configure your phone system to send incoming call details to that URL. Setup takes minutes.
What if the webhook doesn't include a phone number?
Tell Notis which field in the webhook contains the caller phone number. Notis will parse and validate it.
Can I use this to screen calls before they ring through?
Notis returns data quickly. You can use reputation scores to route high-risk calls to voicemail.
