I install invoice ninja on my website, download the mobile app to login and it request that I enter the API_SECRET. I went through the document http://docs.invoiceninja.com/en/latest/mobile_apps.html and i can find the ” .env file”. Pleased I need the file name where the (.env file) so i can work on it. steps, name and location of the file to access (.env file) will be appreciated December 17, 2018 at 5:39 am #17563 Hillel CorenKeymaster The.env file is in the root folder of the project, on some systems files starting with a period are hidden. If you’re talking about the new mobile app the secret is now optional, it’s only needed if you’ve set a value in the .env file.
