You'd like to allow your users to create a prefilled file, with data you already have, for the procedure « une démarche a préremplir ».
To do this, select the fields below that you want to prefill.
You will then find a prefill link at the bottom of this page, which you will just need to copy, adapt by replacing the default values, and share.
In the same way, you will find an example of a cURL request at the bottom of the page to adapt if you want to prefill the folders via API.
