Prepulating via URL parameters: what happens to field names when forms are modified?

Assuming I've created a URL with querystring parameters to prepopulate a form based on its existing fields.

When I modify the form, what happens to the existing field names in the form? Will my existing URL with querystring parameters still work?

Apart from deletion of existing fields, what kinds of modifications to the form will break the existing URL?

Thanks.

No, they might not work, because the unique name for those field will change if you change their labels. So, you will need to update parameters.

So, the only modifications that will stop your existing URL with parameters from working, will be the ones(name changes, or field deletion) that affect those fields that are being prepopulated.

Let us know if you have more questions.

Thank you, that's clear.
