I don’t think we have a built-in way of achieving this. What I’ve seen in signups that require phone verification, is that they verify the number as part of signup flow, and not once the full form has been submitted. Usually this is achieved by doing something like this:
- Having a
phone numberfield, where you input the number, and a “Send code” button next to it - Then, using a SMS API, like Twilio, you deliver a message with the code
- You also show a
verification codefield with aVerifybutton next to it - When the user inputs the code they received via SMS, you use the same API to validate the phone number
- With the validation in place, you now allow your user to submit the signup form
