Every time someone completes a typeform, they have to tap the Submit button, at which point the answers are sent to your account.
This article explains how it behaves and how to edit it.
Where does the Submit button appear?
Respondents will see the Submit button right after the last question or field of your typeform. Tapping the button sends their answers to your Typeform account, and then shows respondents an Ending screen.
Can I change the text of the Submit button?
Yes! Go to Settings by clicking on the gear icon in the right-hand sidebar, then click Messages:
Scroll down until you see Button to send typeform. Click on the text to edit it:
Payment and Statement question behavior with the Submit button
Because the Submit button appears at the end of your last question, it will replace the standard button on Statement and Payment questions.
If your typeform is going to end on a Statement or Payment question, and you want to change the text in the button, you must change the Submit button text, as detailed above.
Simply changing the Button text on the question itself will have no effect. For example, in the Statement question shown below, the user has changed the question Button text from "Continue" to "Fantastic!". However, if the Statement question is the last question in the typeform, this customized button text will not appear. Instead, the button will say "Submit" unless the user changes the Submit button text to say "Fantastic!" as well, following the steps shown above.
