Using Firebase API

Autenticate a new User

Open Sign In Example.vi and update the "API_KEY" and "Firebase URL" with the ones obtained in the previous steps

This Example will add your USER to the autenticated Users list

Post to Real Time DB

Open Log in and Post.vi Example, use your "API_KEY", "Firebase URL" and your Authenticated user to POST something to your Real Time Database, in this example we published a cluster called data, data is the endPoint name

Editing your Rules

Until this point your Real Time Database is open to any autenticated user, we can create rules to match our neads, for example, if this database is meant to be used by a company we can create rules to allow reading and/or writting for an specific domain

Rules Example 1, allow writting and reading from specific domain users:

{
  "rules": {
    ".read": "auth.token.email.endsWith('@domain.com')",  
    ".write": "auth.token.email.endsWith('@domain.com')",  
  }
}

Rules Example 2, allow writting and reading from specific domain and filtering enabled to search under data/date

{
  "rules": {
    "data" : {
                ".indexOn": ["date"]
            },
     ".read": "auth.token.email.endsWith('@domain.com')",  
     ".write": "auth.token.email.endsWith('@domain.com')",  
    
  }
}

After you instal the VIPM Package there is an example provided for you, just drag it into your Block diagram and test it after setup your Firebase Database.
