How to connect to mobile with an online subdomain

Hello,

I hosted Invoice Ninja with Softaculous on my subdomains.

Everything works fine, but how do you connect with the mobile application? I’ve tried everything and nothing’s going well.

He asks me “email + pass mode + url + secret”.
Am I to understand that the secret key is to create an API in API tokens, because I see no other alternative.

Thank you for enlightening me:-)
Thanks

The secret value is optional, you only need to set it if you have it configured in the .env file.
