Automate Google Forms Send Registration OTP with Zapier

Instantly send a registration OTP to new form respondents with a no-code Zapier workflow connecting Google Forms to D7 Messaging. Use form verification OTP to validate phone numbers and ensure secure signups, without manual steps or custom code.

This integration links Google Forms to D7 Messaging through Zapier so every time a respondent submits a form, an OTP is sent to their phone number for quick verification. It helps verify ownership of a mobile number, reduce spam entries, and protect user onboarding flows with secure signups. Whether you’re qualifying leads, approving event registrations, or authenticating new accounts, OTP automation keeps your data clean and your users trusted.

1. Trigger App: Google Forms
2. Trigger Event: Form Submitted a respondent completes your Google Form.
3. Zapier captures the submission and maps the phone number field.
4. Action (D7 Messaging): Send registration OTP an SMS with a one-time passcode is delivered to the respondent.

What do I need to set this up?
A Google account (for Google Forms), a Zapier account, and a D7 Messaging account. Create your form with a phone number field, then build a Zap that maps the phone number to the D7 Messaging action.

How is the OTP generated?
You can generate a one-time code using Zapier (e.g., Formatter/Code step) or your own backend. Pass the code into the D7 Messaging SMS template and store it in your system for verification. Alternatively, use your preferred verification logic to match the code entered by the user.

Can I limit or throttle OTP sends?
Yes. Add Zapier Filters or Delay steps to prevent repeated sends within a timeframe, or check for duplicates before sending. You can also create re-send rules based on user requests or delivery status.

Does this work internationally?
Yes. D7 Messaging supports global delivery. Be sure to collect phone numbers in international format (E.164) for best results and compliant routing.

How long should an OTP remain valid?
Most teams choose 2–10 minutes. Define your expiration and verification logic in your app or workflow and communicate it in the SMS content so users know what to expect.

What are the costs?
Standard D7 Messaging SMS pricing applies, plus any Zapier task usage based on your plan. You only pay for messages sent and the automation tasks you use.
