DNS Lookup API + Twilio Integration

Why connect them

The DNS Lookup API in Twilio.

Twilio enables programmable communications. Integrating APIs with Twilio enables intelligent SMS workflows, validated calling, and data-rich messaging. Build smart communication systems that respond with context.

What you can build

Workflows worth wiring.

Validate phone numbers before sending SMS campaigns

Send personalized messages with data from external APIs

Create intelligent auto-responses based on message content analysis

Route calls based on caller data from lookup APIs

Templates

Ready-made ideas.

Scheduled check detects change Lookup DNS → send SMS if records changed

SMS alert on DNS changes

Monitor critical domains and send an SMS via Twilio whenever records.A or records.NS change unexpectedly from the expected configuration.

New contact added Lookup DNS → verify domain → trigger SMS

Verify domain before sending SMS

Before sending a welcome SMS, verify the contact's email domain has valid records.MX. Only send to contacts with healthy domain DNS.

Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with Twilio as the trigger app and "New SMS received" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the DNS Lookup API, and map your trigger data to the request.
3
Send it back. Add a second Twilio action for "Send SMS" and map the returned fields (like domain) into it.
4
Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.

Set up with Make

1
Add the trigger. Create a scenario and add a Twilio module set to "New SMS received". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/dnslookup with your x-api-key header. Pass the trigger's data as the input.
3
Parse & map. Add a JSON module to read the response, then a Twilio module for "Send SMS". Map fields like data.domain into place.
4
Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.

Set up with n8n

1
Add the trigger node. Start a workflow with a Twilio trigger node for "New SMS received" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/dnslookup using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a Twilio node for "Send SMS" and reference the response with expressions such as {{ $json.data.domain }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.
