Connect it in a few steps.

Set up with Zapier
  1. 1
    Set the trigger. Create a Zap with Twilio as the trigger app and "New SMS received" as the event. Connect your account.
  2. 2
    Add the API action. Add APIVerve as the action, select the Number to Words API, and map your trigger data to the request.
  3. 3
    Send it back. Add a second Twilio action for "Send SMS" and map the returned fields (like number) into it.
  4. 4
    Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.
Set up with Make
  1. 1
    Add the trigger. Create a scenario and add a Twilio module set to "New SMS received". Authenticate your account.
  2. 2
    Call the API. Add an HTTP module pointing at api.apiverve.com/v1/numbertowords with your x-api-key header. Pass the trigger's data as the input.
  3. 3
    Parse & map. Add a JSON module to read the response, then a Twilio module for "Send SMS". Map fields like data.number into place.
  4. 4
    Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.
Set up with n8n
  1. 1
    Add the trigger node. Start a workflow with a Twilio trigger node for "New SMS received" and connect your credentials.
  2. 2
    Add an HTTP Request node. Point it at api.apiverve.com/v1/numbertowords using Header Auth (x-api-key). Feed in the trigger data.
  3. 3
    Map with expressions. Add a Twilio node for "Send SMS" and reference the response with expressions such as {{ $json.data.number }}.
  4. 4
    Execute & activate. Execute manually to verify, then activate the workflow for production.

Twilio + Number to Words API FAQ

How do I validate phone numbers before sending SMS?
Before sending via Twilio, call phone validation APIs to verify numbers are valid, mobile (for SMS), and not on do-not-call lists.
Can I personalize Twilio messages with API data?
Yes. Before sending messages, call APIs to fetch personalized data (weather, account status, etc.) and include it in your SMS or voice content.
How do I route incoming calls based on caller data?
When calls arrive, look up caller information using APIs, then use Twilio Studio or automation platforms to route based on the lookup results.
