The form can be set to submit automatically by adding the parameter system_submit=true. However, if some fields are missing, the form’s validation will trigger an error and the user will be asked to complete the missing fields. (Feature Auto submit must be enabled).
Use case
Auto Submit is especially useful when monetizing a lead generation database. Since you already have all the required user information, the lead can be sent directly into the cascade (e.g., after the user clicks a button in an email).
Optional confirmation step
If you want to add an additional confirmation from the user, you can create a dedicated internal page that the user visits before the form is submitted automatically.
You might also want to check out the Pre-filling fields feature, which automatically prefills the form with values to have it ready to be auto-submitted.
