How do I trigger on an inbound Twilio call?

Short answer: Drop the "TwilioCall Received" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in Twilio, not on a polling schedule.

FAQ

Questions about Call Received.

How does the Call Received trigger work in Twilio?
Fires when a phone call is received on your Twilio number. Use it to log calls into your CRM, route via IVR, or kick off a callback workflow.
Is the Call Received trigger real-time?
Yes. Call Received uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Twilio.
What data does Call Received return?
The full event payload from Twilio. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.
Can I filter Call Received so only some events start a workflow?
Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.
Do I need Twilio admin permissions to use Call Received?
For most Twilio accounts a standard user can authorize the trigger. Some Twilio plans require an admin to enable third-party webhooks. Check Twilio's docs if the trigger fails to register.
