Know who called before you call back
Send an incoming caller number to Notis and get a quick Callerapi screening in your WhatsApp conversation.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send message
Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.
Why this helps
Unknown callers interrupt focused work, and checking each one later can mean missed context or risky callbacks.
- See Callerapi spam results alongside the incoming number.
- Give your team a quick callback decision point.
- Keep screening summaries in a familiar channel.
Setup
Build it in a few focused steps.
- 1Connect Callerapi and Whatsapp once in the Notis portal.
- 2Create an automation and name it for incoming caller screening.
- 3Tell Notis to check each webhook's caller number with Callerapi and send the number and returned spam assessment to your team in WhatsApp.
- 4Pick the Notis webhook trigger and choose where run reports should go.
- 5Test with one real caller number that has texted your WhatsApp number.
